Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car wash device for spraying water, detergent or the like on the car body as the car wash device body or the car runs, and bringing the rotary brush into contact with the car body surface to clean the car body surface. This is intended to improve the performance of a device that employs a brush made of the above-mentioned hair material as a cloth (hereinafter referred to as a cloth brush).

[0002]

2. Description of the Related Art Conventionally, a device using a cloth brush is already known, for example, in Japanese Utility Model Publication No. 50-30233. However, there is no known cloth brush that has been permanently waterproofed against its inherent water absorption and water content. That is, it is widely known that waterproofing is performed not only by brushes but also by spraying a water repellent agent on cloths, but such waterproofing is not permanent, and it continues particularly like car wash brushes. In a usage environment that receives relatively strong physical force, its waterproof effect disappears after several uses, and it is completely impractical, so it is serious to try to waterproof the cloth brush. It was never implemented.

[0003]

In the conventional cloth brush, the cloth as a raw material absorbs water, detergent, etc. sprayed at the time of car washing, and the following problems occur.

A. The cloth material of the brush absorbs water and the weight increases, which causes a strong impact by rotating contact with the vehicle body surface, resulting in car wash damage caused by sand, mud, etc. between the vehicle body and the brush. easy.

B. As the cloth material of the brush absorbs water, the gap between the fibers of the cloth material expands and dirt such as mud easily adheres,
In addition, since the dirt once taken in between the fibers does not easily fall off, the damage of the brush progresses quickly and the adhered dirt acts on the vehicle body surface to cause car wash damage.

C. In cold regions, the absorbed water material freezes and becomes unusable.To prevent this, high-cost equipment such as installing a car wash device indoors to keep warm and installing a defrosting facility such as a boiler is used. Will be required.

D. The cloth material of the brush absorbs even the detergent and wax that are sprayed with the car wash, the detergent and the wax are mixed in the cloth material, and the surfactant components of the detergent and the oil and fat components of the wax are combined, When waxing, the wax could not sufficiently act on the vehicle body. Further, the surface-active component of the detergent and the oil and fat content of the wax become a gel and stay in the cloth of the brush to promote the stain of the brush.

Therefore, a first object of the present invention is to provide a car wash device which is capable of preventing the stain of the brush by providing the cloth brush with a durable waterproof treatment and having a function of cleaning the brush. It is in.

A second object of the present invention is to provide a cloth brush with a durable waterproofing function and to have a function of draining the brush, so that the brush can be used without expensive equipment. It is to provide a car wash device that can prevent freezing.

A third object of the present invention is to provide a cloth brush with a durable waterproofing treatment, in which a rotating brush sprays a detergent for brushing and a wax sprays for waxing. It is an object of the present invention to provide a car wash device capable of effectively waxing even if it is also used as a vehicle.

[0011]

According to the present invention, there is provided a car wash apparatus for cleaning a vehicle body surface by spraying water, detergent or the like on the car as the car wash apparatus body or the car travels, and bringing a rotating brush into contact therewith. The rotating brush is made of cloth that is waterproofed by resin direct coating, and is characterized by being able to perform a brush cleaning operation that sprays water toward the rotating brush and rotates the brush at a higher speed than during car wash operation. That is, the first problem is solved.

Further, according to the present invention, in the car wash device for spraying water, detergent or the like on the car as the car wash device main body or the car runs, and contacting the rotary brush to clean the vehicle body surface, the rotary brush is made of resin. The second problem was solved by using a cloth that is waterproofed by direct coating as a bristle material and being able to appropriately perform a draining operation in which the rotating brush is idled at a higher speed than during a car washing operation. It is a thing.

Further, according to the present invention, in the car wash device for spraying water, detergent, wax or the like on the car as the car wash device main body or the car runs, and bringing the rotary brush into contact with the car body surface, the rotary brush is used. Is used for both brushing cleaning by spraying detergent and waxing by spraying wax, and the bristles of the brush are waterproofed by resin direct coating. This is intended to solve the problem of item 3.

[0014]

[Function] With the above structure, the cloth as the material of the cloth brush is
Waterproofing by resin direct coating is applied,
The amount of water, detergent, etc. sprayed during car washing is extremely small. Therefore, the increase in weight of the brush cloth material due to water absorption is small, and even if the brush cloth material is rotationally contacted with the vehicle body surface, an excessive impact force is not applied, so that car wash damage is prevented. In addition, since the cloth material of the brush hardly absorbs water, dirt does not adhere to the gaps of the fibers of the cloth due to water absorption, and the brush is less likely to be damaged. As a result, the adhered dirt acts on the vehicle body surface to wash the car. It also prevents scratches. Further, since the cloth material absorbs little water, it can be easily drained and dried, and even if the brush is frozen, it can be easily thawed, so that it can be used in cold regions without requiring specially expensive equipment.

The resin direct coating is
A coating agent made by mixing a water repellent component such as organopolysiloxane with a component having a fixing action on the fiber such as polyisocyanate compound is applied to the cloth material, allowed to penetrate, and then heat-treated for addition, polymerization or crosslinking reaction. This means that a water-repellent component such as an organopolysiloxane is bound to a fixing component such as an isocyanate group to firmly cover the cloth fiber and a permanent water-repellent effect is obtained.

Further, even if dirt is attached to the cloth brush by car washing, the cloth itself hardly absorbs water, so that the dirt does not enter into the gaps between the fibers, and water is jetted toward the cloth brush to make it more than the car washing operation. By making it possible to perform the brush cleaning operation of rotating the brush at a high speed, it is possible to almost completely wash off the attached dirt.

Further, since the cloth material of the brush hardly absorbs water, the water adhering to the brush due to the car wash can be easily idled by idling by making it possible to appropriately execute the water draining operation in which the rotating brush idles faster than the car washing operation. It can be scattered and dried.

Moreover, since the cloth brush is permanently waterproofed and does not absorb the detergent or wax sprinkled by the car wash, the detergent and wax are mixed and adhered to the brush. It does not reduce the effectiveness of the wax, nor does the brush become soiled by the mixture of detergent and wax. As a result, even if the cloth brush is used for both brushing cleaning using a detergent and waxing, a highly effective car wash can be performed.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view mainly showing a front external view of a car wash apparatus as an embodiment, and FIG. 2 is a side view explanatory view showing a constitutional arrangement of respective parts of the apparatus of the embodiment. Here, the car wash machine body 1 formed in a gate shape and traveling back and forth on the rails 2, 2 is
A so-called gate-type car washer is shown as an example, in which the car body is washed by running over a car A parked in between. In addition,
In addition to this, there is also known a car washing apparatus of a type in which a car washing machine main body is fixedly installed and a car is conveyed to the car washing machine by a conveyor or the like, and the car washing machine can be similarly implemented in this type of apparatus.

The car wash main body 1 includes an upper surface rotating brush 3 configured to be able to move up and down along the upper surface shape of the automobile A, and a pair of side surface rotating brushes which can be opened and closed along the side surface shape of the automobile A. 4, 4 and the nozzle 5 for injecting water or various liquid agents onto the automobile A or the rotating brushes 3, 4, 4.
6, 7, 8 are provided, and while the main body 1 travels, the rotating brushes 3, 4, 4 are brought into contact with the automobile A while appropriately spraying water, detergent, etc. from the nozzles to clean the vehicle body surface. An operation panel 9 is provided on the front surface of the car wash machine body 1. In addition to the rotating brush and the nozzle, a known blower device for drying the car body after car washing is provided, but the description thereof is omitted here.

The nozzle 5 is located on the most front side of the main body 1 (the left side is front in FIG. 2) and jets water exclusively toward the automobile A. The nozzle 6 is located immediately in front of each of the rotating brushes 3, 4, and 4, and mainly sprays detergent and wax toward the automobile A and the brushes 3, 4, and 4. The nozzle 7 is located at the rear of each of the rotating brushes 3, 4, 4 and
Water is mainly sprayed toward 4, 4. The nozzle 8 is located at the rearmost side of the main body 1 and sprays the foaming detergent and water toward the automobile A.

Each of the rotary brushes 3, 4, and 4 uses a cloth 10 waterproofed by a resin direct coating described later as a bristle material. The material of the cloth 10 is a woven cloth called tricot, and has a more preferable property as a material of the brush such as higher shape retention and excellent durability as compared with a non-woven fabric conventionally known as a brush bristle material.
The cloth used as the material is brushed on one side with a pin roller to improve the softness of the cloth, and the cushioning property due to the brushing is added to the cloth, which makes it extremely soft against the vehicle body.

Then, a resin direct coating is applied to the non-raised surface of this cloth which is not napped.
Resin direct coating will be described in detail later,
By directly coating the fibers that make up the fabric,
If you coat the raised surface, the raised fibers will adhere to the surrounding fibers, and the advantages such as cushioning due to raised corners will be lost.Therefore, the non-raised surface is coated, and the fabric is permanently waterproofed. And the advantages of brushing are compatible.

As shown in FIG. 3, the cloth used in this example is provided with a resin direct coating so that the cloth permeates from the non-raised surface to the base of the raised fibers on the raised surface.
As a result, the cloth itself exerts a permanent water-repellent effect by the coating, while the napped fiber retains the original hydrophilicity of the fiber and can effectively remove the dirt adhered to the vehicle body surface and swollen by water spray.

As shown in FIG. 4, the cloth 10 to be used as the bristle material is a long cloth cut into a predetermined width W, and cuts 11 are made at predetermined intervals L, and the tips of the cuts 11 are formed. A stop hole 11h for preventing the expansion of the cut is bored in the hole. The edge on the cut side is alternately repeated by mountain fold (dotted line portion in FIG. 4) and valley fold (dotted line portion in FIG. 4) between the cuts 11, and each is folded into a fan shape. The portion is riveted to the pipe 12 which is the core material of the brush as shown in FIG.

The cloth 10 has only one surface raised, and the raised surface has a preferable property for car washing as described above. Therefore, make sure that the raised surface of the cloth always contacts the vehicle body.
As shown in FIG. 6, the fabric is folded back to the back side so that the raised surface is the front side, and the edge portion is sewn by a predetermined width D on the non-incision side, that is, the side to be the bristle tip. As a result, a brushed surface appears on both the front and back of the bristle tip portion that comes into contact with the vehicle body, and highly effective cleaning can be performed.

The cloth 10 moves 90 times while it goes around the pipe 12.
It is riveted at four points at intervals, and the riveting points are spirally arranged with respect to the pipe 12 by shifting them up and down by a predetermined dimension, and as a result, a continuous long cloth is spirally attached to the pipe 12. It is wound into a shape and completed as shown in FIG. In this way, by making the cloth 10 spiral, when the brush rotates, the edge forming the brush outer circumference of the cloth 10 comes into contact with the vehicle body in a continuous trajectory, and brushing without washing residue is performed. It will be possible.

In the resin direct coating, a resin and necessary additives are mixed and dissolved in a solvent, a coating agent having an appropriate viscosity is applied to a cloth, which is dried and further heat-treated to form a fiber inside the cloth. And a waterproof drop that forms a resin film on the cloth. As a coating agent for this resin direct coating, an acrylic resin or urethane resin coating agent may be used, but a reactive organopolysiloxane having a hydroxyl group or a hydrogen group, an organopolysiloxane reaction catalyst, and a polyisocyanate. A mixture of the compound and an organic solvent is preferable.

The preferred coating agent will be further described. In this example, 100 parts by weight of a reactive organopolysiloxane having a hydroxyl group or a hydrogen group, 0.1 to 10 parts by weight of a reaction catalyst of the organopolysiloxane, and a polyisocyanate are used. 0.1 to 40 parts by weight of the compound and an appropriate amount of an organic solvent are mixed to obtain a viscosity of 1000 to 100000.
It is preferable to perform resin direct coating with a coating agent adjusted to Cp. When the coating agent is used in this way, it is formed by applying the coating agent, drying it, and further heat-treating it to complete the addition, polymerization or crosslinking reaction between the reactive organopolysiloxane and the polyisocyanate compound. The resin coating can be made stronger.

As the reactive organopolysiloxane, for example, "TBS-25ER" manufactured by Toupe Co. can be used. This product is a waterproofing agent for fibers containing 15% of solid content obtained by dissolving a reactive liquid organosilicone polymer having a hydroxyl group and a liquid organosilicone polymer having a reactive hydrogen group in trichlene.
As the reaction catalyst for this reactive organopolysiloxane, "Cat.TM." manufactured by the same company can be used, but in general, organic acid such as zinc, lead, zirconium, tin, or organic acid salt of an organic metal compound is used. Can be used.
By mixing "Cat TD" manufactured by the same company, the adhesiveness between the coating agent and the cloth surface can be improved.

As the polyisocyanate compound, diphenylmethane diisocyanate such as "Millionate HT" manufactured by Nippon Polyurethane Industry Co., Ltd. is used, but tolylene diisocyanate, hexamethylene diisocyanate and the like can also be used. If necessary, these polyisocyanate compounds may be used in combination, or a part of the isocyanate groups in the polyisocyanate compound may be blocked with a polyol for use.

The organic solvent is for facilitating the coating work on the cloth surface and for assisting the permeability to the cloth. For example, trichlorethylene, perchlorethylene,
1,1,1-trichloroethane, toluene, xylene,
Mineral spirit or the like can be used.

The composition ratio of the coating agent is preferably in the above-mentioned range. Particularly, when the polyisocyanate compound is excessively blended, the waterproof property of the resin coating is lowered, so that the polyisocyanate compound is contained in the total amount of the coating agent. It is desirable to mix in a weight ratio of 1: 3 to 1:15. Further, this preferable coating agent can be used in combination with an acrylic resin-based or urethane resin-based coating agent.

Waterproofing by resin direct coating can be performed based on the flow shown in FIG.
First, 100% of the above coating agent with an organic solvent.
Adjust the viscosity in the range of 0 to 100,000 Cp (St
1). The viscosity is appropriately adjusted according to the material of the cloth used and the performance of the coating device. Next, the above-mentioned viscosity-adjusted coating agent is directly applied (St3) onto the non-raised surface of the cloth cut into the predetermined shape and size (St2) using an application device such as a knife coater or a roll coater. The coating amount varies depending on the type of coating agent and the type of cloth, but is about 130 to 350 g / m ^{2 in the} wet state.

Then, the cloth coated with the coating agent
The resin film is dried by leaving it at a temperature of 0 to 100 ° C. for about 30 seconds to 5 minutes to evaporate the organic solvent (St.
4). After the completion of this drying process, the cloth covered with the resin coating,
Waterproofing is completed by performing heat treatment for 10 seconds to 5 minutes at a temperature of 120 to 180 ° C. to complete the addition, polymerization or crosslinking reaction between the reactive organopolysiloxane and the polyisocyanate compound ( St
5).

As described above, according to the preferred coating agent, not only the coating agent can be sufficiently permeated into the fibers and the cloth of the cloth to form the resin film, but also the addition, polymerization or cross-linking reaction is carried out thereafter, so that the resin film is formed. Adheres firmly to the texture. In addition, since the reactive organopolysiloxane that is the waterproof component is bound to the isocyanate group of the polyisocyanate compound by addition, polymerization or crosslinking reaction, compared to the waterproof treatment of simply spraying a water repellent on a conventionally known fabric. , Can be maintained waterproof for much longer. In addition, this waterproofing, since it penetrates into the cloth and coats the cloth and the fibers themselves, it is possible to improve the strength of the fibers and the shape retention of the cloth,
The durability and shape retention of the cloth can be greatly improved. If an antibacterial agent is added to the coating agent,
It is possible to more surely prevent the generation of mold.

For the rotating brushes 3, 4 and 4 constructed as described above, mainly to confirm the performance of waterproofing by resin direct coating, a rotating brush waterproofed by resin direct coating and a waterproofing A comparative experiment was performed with a rotating brush made of the same material that was not applied. The comparative experiment was carried out for each item of water content, adhesion amount of earth and sand, frozen state, shape retention state and dirt state when actually used for car washing under the same conditions.

In a comparative experiment, the water content was determined by subtracting the weight of the rotating brush before washing from the weight of the rotating brush immediately after washing. The amount of adhered soil is 10 cm ² after washing the car.
The number of sand grains and the like remaining per hit was observed and measured with a loupe.
As for the frozen state, the appearance of the frozen cloth 10 observed under the temperature of -4 ° C was visually observed. As for the shape-retaining state, the appearance of the shape-retaining state after 50 times of car washing was visually observed. As for the stain state, the degree of stain after 50 times of car washing was visually observed. Table 1 shows the results.

[0039]

[Table 1]

As is apparent from Table 1, the waterproof rotating brushes of the examples are waterproofed for all items including the water content, the adhered amount of earth and sand, the frozen state, the shape retention state and the soiled state. It was possible to obtain better results than the rotating brush which was not applied. Further, with respect to the rotating brush which is waterproofed in the example, the number of washings is 5 times and 10 times.
The water content was determined after washing the car 20 times, 30 times, 40 times, and 50 times. As shown in Table 2, it was found that the water content did not increase and the waterproofing effect remained unchanged. .

FIG. 9 is a block diagram showing the control system of the apparatus of the above embodiment. Reference numeral 13 denotes a control board incorporated in the car wash main body 1, which includes a microcomputer and outputs a signal to the drive board 14 in response to an operation input from the operation board 9 to give a predetermined car wash operation programmed. Drive board 1
4 carries out energization operation of each part in response to a signal from the control board 13, forward (forward) / reverse (reverse) / stop of the main body 1, low speed rotation / high speed rotation / stop / up of the upper surface rotating brush 3. / Descent, low speed rotation / high speed rotation / stop / open / close of the side rotary brushes 4,4, injection start / stop from each nozzle 5,6,7 / switching of liquid agent. As described above, the rotary brushes 3, 4, 4 can be driven to switch between low-speed rotation and high-speed rotation. Brushing cleaning is performed at low-speed rotation during normal car washing, and high-speed rotation is performed during brush cleaning operation and draining operation described later. It is what is done.

The operation board 9 is provided with a conventionally well-known car wash course selection key, a designation key for inputting a vehicle type, presence / absence of a protrusion, etc. (note that these well-known keys are not shown). A cleaning key 15 for providing a cleaning operation and a draining key 16 for providing a draining operation of the brush are provided.

When the cleaning key 15 is pressed, the rotary brushes 3, 4 and 4 are driven at high speed to drive the nozzles 6 and 7.
The water is sprayed from and the brush cleaning operation is executed for a predetermined time. The rotating brushes 3, 4, 4 first rotate forward in a fixed direction at a high speed for a fixed time, and then reversely rotate in a reverse direction at a high speed for a fixed time thereafter. During this time, the jetting of water from the nozzles 6 and 7 is continued, and the dirt attached to the brush is washed away together with the water jetted toward the brush. Finally, the jetting of water from the nozzles 6 and 7 is stopped, and only the rotating brush is normally rotated at high speed to drain water, and a series of brush cleaning operations is completed in about 1 to 3 minutes.

When the draining key 16 is pressed, the rotary brushes 3, 4, 4 are driven at high speed. Here, water is not sprayed from the nozzles at all, and the brush is simply idled. First, the rotating brushes 3, 4 and 4 idle at a high speed in a certain direction for a certain period of time, and then at a high speed in the opposite direction for a certain period of time, ending the operation. The required time is about 30 seconds to 2 minutes. Since the cloth 10 itself, which is the bristle material of the brush, absorbs almost no water due to the waterproofing process, this idle rotation causes the water droplets adhering to the raised surface to be quickly scattered to dry the brush.

The brush cleaning operation and the water draining operation described above can be carried out in a series of car washing operations. Hereinafter, the brush cleaning operation and the water draining operation performed at the same time as the car wash will be described based on the time chart of FIG. Here, a case will be described as an example where the car wash machine body 1 travels back and forth two times to perform operations of cleaning, waxing and drying the vehicle body.

First, as the car wash machine body 1 goes forward for the first time, water is jetted from the nozzles 5, 7 and 8 and detergent is jetted from the nozzle 6, and the rotary brushes 3, 4 and 4 are rotated at a low speed. Then, the first cleaning step of brushing and cleaning the vehicle body is performed. Here, the main focus is to quickly wash away dirt, such as sand and mud, that adheres to the vehicle body, which is likely to cause car wash damage, by using a relatively large amount of water. Water is constantly jetted from the nozzle 7 to the rotating brushes 3, 4, and 4,
Care is taken to prevent dirt from the vehicle body from adhering to the brush cloth 10.

Following the first return of the car wash machine body 1,
While spraying the detergent foamed from the nozzle 8 onto the vehicle body,
A second cleaning step is performed in which the rotating brushes 3, 4, 4 are rotated at a low speed to brush the vehicle body again. here,
The main focus is to remove stains, such as oil stains, that are difficult to remove with water only, by uniformly applying a detergent, which has been foamed to improve the adherence to the car body, with a brush.
Finally, water is sprayed from the nozzle 5 to wash away the detergent remaining on the vehicle body along with dirt.

After the completion of the second cleaning step by the first return, the traveling of the main body 1 is temporarily stopped and the brush cleaning operation is executed. Each of the rotating brushes 3, 4, 4 is driven at high speed to jet water from the nozzles 6, 7, 8. Here, the main purpose is to wash away the amount of detergent attached to the brush, and the work is completed in about 10 to 30 seconds. The purpose of spraying water from the nozzle 8 is to wash away the foaming detergent remaining in the nozzle 8 and prevent the nozzle 8 from being clogged by the residual detergent.

Following the second going of the car wash machine body 1,
A wax process is performed by jetting wax from the nozzle 6 and rotating the rotating brushes 3, 4, 4 at a low speed. The wax is sprayed on the surface of the vehicle body immediately before being brushed and brushed, and the wax is rubbed into the vehicle body with a brush to achieve a uniform and even wax finish. Finally, water is sprayed from the nozzle 8 to wash away excess wax remaining on the vehicle body.

After the completion of the wax process, the water draining operation is executed. Each of the rotating brushes 3, 4, 4 is driven at a high speed to rotate freely, and the purpose is to easily shake off water and wax adhering to the brush.
It is completed in a short time of about 0 seconds, and is executed while the main body 1 is switched from forward to reverse, and it is not necessary to particularly stop the traveling of the main body 1 for draining work. After that, the car wash main body drives the blower device (not shown) to dry the vehicle body along with the second backward travel, and the series of car wash operations is completed.

This embodiment operates as described above, and the brush cleaning operation can be executed as necessary to keep the rotary brushes 3, 4, 4 in a clean state. In particular, the cloth 10 of the brush does not absorb water due to the above-described waterproofing, and the fibers swell due to the absorption of water to expand the gap between the fibers,
No dirt will get in here. For this reason,
Even if the cloth 10 is contaminated, it is often adhered to the raised fiber portion through water as an intermediary, and the adhered dirt can be easily removed by the brush cleaning operation. Further, since the cloth 10 is waterproofed, the water adhering to the brush can be easily scattered and removed by performing the water draining operation, and even if the cloth 10 is used in cold regions, the brush freezes and is completely removed. There is no possibility of becoming unusable.

[0053]

The present invention is constructed as described above, and the rotating brush uses a cloth cloth waterproofed by resin direct coating as a bristle material, and absorbs water, detergent, etc. sprayed during car washing. Very little
The weight increase of the brush cloth material due to water absorption is small, and an excessive impact force is not applied even when the brush cloth material is rotationally contacted with the vehicle body surface, so that car wash damage is prevented. In addition, since the cloth material of the brush hardly absorbs water, dirt does not adhere to the gaps of the fibers of the cloth due to water absorption, and the brush is less likely to be damaged. As a result, the adhered dirt acts on the vehicle body surface to wash the car. It also prevents scratches.
Furthermore, since the cloth material absorbs little water, it is easy to drain and dry,
Moreover, even if the brush freezes, it can be easily thawed and can be used in cold regions without requiring specially expensive equipment.

Further, even if dirt is attached to the cloth brush by car washing, the cloth itself hardly absorbs water, so that the dirt does not enter into the gaps between the fibers, and water is jetted toward the cloth brush from the time of car washing operation. By making it possible to perform the brush cleaning operation of rotating the brush at a high speed, it is possible to almost completely wash off the attached dirt.

Further, since the cloth material of the brush hardly absorbs water, the water adhering to the brush by the car wash can be easily rotated by idling by making it possible to appropriately execute the water draining operation for idling the rotating brush at a higher speed than the car washing operation. It can be scattered on the surface for drying, and there is no concern that the brush will freeze even in cold regions.

Moreover, since the rotating brush is permanently waterproofed and does not absorb the detergent or wax even if it is sprinkled with a car wash, the detergent and wax are mixed and adhered on the brush. It does not reduce the effectiveness of the wax, nor does the brush become soiled by the mixture of detergent and wax. As a result, even if the cloth brush is used for both the brushing cleaning using a detergent and the waxing, a highly effective car washing can be performed.
