Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning method and a cleaning material for an automobile body, which can easily remove iron powder, pitch, tar, etc. adhering to the automobile body, for example, so as not to damage the coating after waxing. With regard to the above, in particular, a conventional cleaning tool of this type kneads the dirty surface inward when dirt adheres to the surface, but the present invention recovers to a clean clay layer surface with a cleaner liquid and cleans it. The present invention relates to a cleaning method capable of continuing work and a cleaning material for an automobile body.

[0002]

2. Description of the Related Art Conventionally, iron powder scattered around factories and railroads and brake dust adhere to the body of a vehicle during running. Therefore, waxing without removing these powders makes up the painted surface that makes up the body of the vehicle. Iron powder, etc. attached to (coating film) may pierce deeper, scratch the painted surface, or cause rust. Therefore, conventionally, a method of using lumpy clay as a cleaning tool is known. That is, this cleaning tool (clay) is in the form of a lump having a size that can be grasped with one hand, and by sliding the clay onto the car body while running water, iron powder etc. adhered to the painted surface can be removed. The method is to transfer it to the clay side and remove it from the painted surface.
Then, when the soil of the clay becomes large to some extent, the soiled surface is kneaded inward to form a clean surface, and the cleaning work is continued.

[0003]

However, since the conventional cleaning tool (clay) is heavy in itself, the work of sliding the surface to be cleaned causes a great deal of fatigue to the worker having a comparatively weak force. Met. In addition, the work of directly grasping the clay and sliding the surface to be cleaned is a work that gives a significant discomfort because the hands, fingertips, and nails may become soiled or stickiness may remain on the fingertips. In particular, when this clay is repeatedly used, stains previously kneaded inward appear again on the surface, and the stains may adhere to the hands and fingertips, which further increases the discomfort.

Further, as described above, the conventional cleaning tool (clay)
Since it needs to be kneaded when the stain becomes large, it causes a great deal of fatigue especially to the fingertips, and it is also a pain for an operator having a comparatively weak force. Moreover, since clay in the winter and the like is harder than in the summer, this kneading work was even more difficult in the winter. Furthermore, when this clay is repeatedly used, stains that have been previously kneaded inside may partially reappear on the surface, making it difficult to form a clean surface and making kneading work more difficult. . If you do not notice that the solid material kneaded before appears again on the surface, if you perform the cleaning work, you will press the solid material against the painted surface, which may cause scratches or rust on the painted surface. There were times when it happened. By softening the clay, the above kneading work becomes relatively easy,
When the clay is made soft, problems such as the shape of the clay being changed by the gripping pressure of the hand during the work of pressing the clay against the automobile body and rubbing it occur. Further, since the work of kneading clay is carried out by directly touching the clay with the hand as in the work of sliding the surface to be cleaned, it is a work which gives a significant discomfort similar to or more than the above. In particular, when this clay is used repeatedly, stains that have been kneaded inward will appear again on the surface, so the stains may adhere to the hands and fingertips, or the solid matter may scratch the fingertips, causing more discomfort. Was increased.

On the other hand, a space is formed on one surface of a sponge,
There is also proposed a product in which clay is inserted (played loosely) into the space and slid on the automobile body. This product has the advantage that the operator can grasp the sponge and remove iron powder etc. without directly touching the clay, and that relatively soft clay can be used. When dirt is accumulated, it is necessary to knead as described above to form a clean surface, so that the above-mentioned problem has not been solved at all.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and provides a cleaning tool in which a clay layer having a thickness of 2 to 10 mm is provided on at least one surface of a foamed resin molding, and the surface of the clay layer is By sliding on the surface to be cleaned so as to come into contact with the surface to be cleaned while interposing a lubricating liquid, after transferring the solid matter or liquid dirt attached to the surface to be cleaned to the clay layer, The present invention relates to a cleaning method characterized by recovering a clean clay layer surface by removing solids and liquid stains transferred to the surface of a clay layer using a cleaner liquid. still,
The "cleaning" in the cleaning method of the present invention refers to a primary cleaning for removing solids and liquid stains adhered to the surface to be cleaned, basically removing liquid stains firmly adhered to the surface to be cleaned. Carry out before the included secondary cleaning.

The present invention also provides a cleaning tool comprising a foamed resin molded body provided with a clay layer having a thickness of 2 to 10 mm on at least one surface thereof,
A cleaning material for an automobile body is also proposed, which is composed of a cleaner liquid for removing solid matter and liquid stains transferred to the surface of the clay layer.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The cleaning method of the present invention will be described by taking cleaning of an automobile body as an example. In this case, the surface to be cleaned is an automobile body, the clay layer is oil-based such as oily putty, the lubricating liquid is water-based (lubricating water), and the cleaner liquid is oil-based such as an oily solvent.

The cleaning tool comprises a foamed resin molded body and a clay layer having a thickness of 2 to 10 mm formed on at least one surface thereof. The foamed resin molded body is a grip portion for an operator to hold the cleaning tool in his / her hand.The foamed resin molded body is normally formed to have a thickness of about several cm, but it can be stably gripped, and when it is gripped, the clay layer is manually held. The material composition and the shape composition are not particularly limited as long as they are not touched by a finger. A sponge-like molded body that has elasticity and has continuous voids can be stably held so that the fingertip will bite when gripped, and since it can hold lubricating water and the like inside, It is desirable that the dirt can be removed while replenishing the lubricating water when the cleaning tool is gripped and slid on the automobile body in the dirt removal work.

For the clay layer, as the material composition, the agglomerated clay (clay-like composition) used as a cleaning tool of this kind, that is, various proposals as an oily putty or a plastic soft whetstone can be used. It has water resistance such that it does not dissolve or swell with lubricating water or the like. As described above, the thickness of the clay layer is 2 to 10 mm, which is thin. If the thickness is more than 10 mm, the clay layer is easily deformed into distorted parts and the entire cleaning tool becomes heavy. on the other hand,
If the thickness is less than 2 mm, it is possible to transfer the solid matter such as iron powder at first, but in the present invention, the surface of the clay layer is recovered cleanly by the cleaning operation described below and repeatedly used. Since the purpose is to do so, the number of times of use and the period of use are extremely short, which makes the product expensive for users.

The cleaning tool used in the present invention is one in which a thin clay layer containing the required minimum amount of clay is integrally fixed to at least one surface of the foamed resin molded body. It is extremely light in weight as compared with the cleaning tool used as it is, and therefore, the work of gripping the foamed resin molded body and sliding it on the automobile body can be performed very easily.

Lubricating water is intervened in the work of gripping the cleaning tool and sliding it on the automobile body. As the lubricating water, mere tap water is used to flow through a hose and various surface active agents are used. It may be performed while spraying the aqueous solution containing the agent. By using the lubricating water in this way, the wettability is improved and the transferability of solid matter or liquid dirt to the clay layer is improved. Furthermore, when lubricating water containing a surfactant is used, the action of washing the automobile body is significantly improved, and a more beautiful washing surface is obtained. The strongly adhered liquid stains may be left to the subsequent cleaning, or may be removed at the same time by using a cloth or a brush. In addition, such a lubricating water can produce the same effect as the above even if it is applied to the method in which the conventional lumpy clay is used as it is as a cleaning tool, but since the lumpy clay is directly gripped and worked. Occasionally, the hands and the lumpy clay become slippery and the workability deteriorates. But,
Since the cleaning tool of the present invention uses the foamed resin molded body as the grip portion, it is not necessary to touch the clay layer and the lubricating water.
Workability does not deteriorate even if lubricating water containing a surfactant is used.

After the dirt has been transferred to the clay layer to some extent by carrying out the above-described cleaning work, the dirt transferred to the clay layer is removed using a cleaner liquid. As the cleaner liquid used here, an oil-based, that is, an oil-based solvent is used for the oil-based clay layer as described above. For example, in the case of automobile bodies, a paraffin-based solvent such as kerosene is preferably used. That is, as the cleaner liquid, one having a high affinity for the clay layer (including solubility, swelling property, etc.) is used, but as the cleaner liquid for the car body, after cleaning the dirt, the car body (painted surface) is washed again. In some cases, the oily solvent that does not affect the coated surface and does not remain is preferable because it may continue. Then, a small amount of this cleaner liquid is applied to the surface of the clay layer on which dirt has been transferred and lightly rubbed with a brush or a spatula, so that solid matter or liquid dirt can be removed extremely easily. At that time, since the amount of the clay layer removed along with solids and liquid stains is extremely small, compared to the conventional type in which dirt is kneaded into the inside by directly using thick clay as a cleaning tool. Clay is efficiently used, and comparing the amounts of clay used, it is possible to carry out a large number of washing operations with a capacity of about 1/10 to 1/2 that of conventional lumpy clay.

As described above, according to the cleaning method of the present invention, the cleaning operation can be easily performed, and further, the work of kneading the dirt into the inside is not required as in the case of using the conventional lumpy clay as it is as a cleaning tool, and a small amount can be used. It is possible to recover a clean clay layer surface very easily using the above-mentioned cleaner liquid.

The cleaning method of the present invention is not limited to the automobile body, and can be applied to various kinds of surfaces to be cleaned to which solid matters and liquid stains are attached. It can be suitably used for applications that may damage the surface. For example, screens and water repellent glass surfaces as objects other than automobile bodies will be described below.

Generally, since the screen door is made of a plastic mesh, if the solid powder such as iron powder is washed with a general cleaning tool such as a brush and a detergent, the iron powder is removed by the brush. I was rubbing it on, and the plastic mesh was damaged or partially broken.
When applying the cleaning method of the present invention to such a screen door (mesh portion), as in the case of cleaning the automobile body,
The clay layer may be oil-based such as oily putty, the lubricating liquid may be water-based (lubricating water), and the cleaner liquid may be oil-based such as an oil solvent. Then, the lubricating water containing the surfactant is first sprayed with a mist, and subsequently, a solid substance such as iron powder is transferred to the clay layer of the cleaning tool. If necessary, a cloth, a brush or the like may be used to remove liquid stains firmly attached to the screen door. The subsequent work of removing dirt on the surface of the clay layer with the cleaner liquid may be performed in the same manner as in the case of cleaning the automobile body described above. Since the lubricating water to which the surfactant is added also performs the cleaning action, the subsequent cleaning can be reduced or omitted. In addition, when the clay layer is strongly pressed and slid on the mesh portion of the screen door, the clay layer may be scraped off. Therefore, the clay layer is relatively weakly pressed and slid. Further, it is also effective to strongly press the clay layer so as to bite into the mesh portion to transfer the dirt attached to the side portion of the mesh. At that time, grid-shaped recesses are formed in the clay layer due to the mesh, but after cleaning the dirt transferred to the clay layer with a cleaner solution to clean it, press it against a smooth surface to smooth it. All you have to do is to return it to a smooth surface. As described above, the surface to be cleaned applied to the present invention is not limited to the smooth surface and may be a surface having a groove or the like.

Since a large amount of dust and dirt in the air adheres to the glass surface of buildings in urban areas, it is regularly washed and water repellent treated, but conventionally it remains after washing with a water-based detergent. The water was wiped off and coated with various oil-based water repellents. When the cleaning method of the present invention is applied to such a glass surface, since an oil-based water repellent (oil-based water repellent) is used as the lubricating liquid, an aqueous one may be used as the clay layer and the cleaner liquid. . Then, first supply an appropriate amount of oily water repellent to the glass surface, then transfer solid matter such as dust and dust or liquid dirt to the water-based clay layer of the cleaning tool and apply the oily water repellent to the glass surface. (Thinly stretch). Liquid stains firmly adhered to the glass surface may be removed with a cloth or a brush. That is, the cleaning operation and the coating operation of the water repellent agent are performed at the same time, and the labor of the operation can be greatly reduced without using water, and the operation time can be shortened. Subsequent work for removing dirt on the surface of the clay layer with the cleaner liquid is the same as that for cleaning the automobile body described above, although there is a difference between the water system and the oil system.

In addition, the cleaning method of the present invention is applied to various kinds of surfaces to be cleaned by appropriately selecting the clay layer, the lubricating liquid and the cleaner liquid in consideration of the material of the surface to be cleaned and the like. be able to.

The cleaning material for automobile bodies of the present invention is
It is composed of a combination of the cleaning tool and the cleaner liquid having the above-mentioned configuration, and as described above, the clay layer constituting a part of the cleaning tool is extremely thin, and the amount of the cleaning liquid used at one time is extremely small. In addition, it is lighter than the conventional cleaning tools made of lumpy clay. For example, as described above, in the clay layer of the cleaning tool used in the present invention, the amount of clay used is 1/10 to 1 / compared with the conventional cleaning tool made of massive clay.
Since the weight is about 2, the weight is about 1/10 to 1/2 (the weight of the foamed resin molded body is extremely light). Furthermore, a set of cleaning materials may be combined with a removing tool such as a brush used when removing dirt using a cleaner liquid.

First, as shown in FIG. 3A, the foamed resin molded body 1 of the cleaning tool 3 with the protective film 4 removed is grasped by hand, and the clay layer 2 with the lubricating water (tap water) 9 interposed. Is the car body (cleaning surface)
Wash by sliding to contact 10. During this cleaning operation, iron powder, pitch, tar, etc. adhering to the automobile body (surface to be cleaned) 10 are transferred to the surface of the clay layer 2. Then, on the surface of the clay layer 2, a certain amount of dirt 1 such as solid matter
When the transfer of No. 1 is performed, a few drops of the cleaner liquid 5 are dropped as shown in FIG. 3B, and the dirt 11 is removed by the remover 8 (brush portion 6) as shown in FIG. 3C. . At that time, a part of the clay layer 2 is removed together with the dirt 11, but the amount is extremely small. Further, when the dirt 11 is a relatively large solid matter, it may be removed at the tip of the blade portion 7 of the removing tool 8 as shown in FIG. In this way, the beautiful clay layer 2 surface is restored by a simple operation, and the cleaning operation can be continued again.

The cleaning using the cleaning material for an automobile body according to the present invention, as described above, can completely soil the hands both during the cleaning operation of the surface to be cleaned 10 and the dirt removing operation (cleaning operation of the cleaning tool 3). Moreover, since the cleaning tool 3 is lightweight, any work can be performed very easily, and it was confirmed that the work can be performed extremely easily and efficiently as compared with the conventional cleaning tool using the lumpy clay. .

[0024]

As described above, the cleaning method of the present invention is one in which a thin clay layer is integrally fixed to at least one surface of a foamed resin molded body, and is used as a conventional cleaning tool in which lumpy clay is used as it is. Compared to this, it is extremely lightweight because it has a thin clay layer using the minimum required amount of clay, so it is extremely easy to grip the foamed resin molded body and slide it on the surface to be cleaned. it can. Further, when using conventional lumpy clay as it is as a cleaning tool, it was necessary to knead the dirt inward, but in the present invention, such a work is not required at all, and a small amount of cleaner liquid is used. It is very easy to recover a clean clay layer surface and a very large number of repeated washing operations can be carried out. Further, in the automobile body cleaning material of the present invention, a film or the like may be used to prevent drying, and the film or the like may be easily detached during use and storage. That is, in order to prevent drying with the conventional lumpy clay, it was necessary to enclose (close) the lumpy clay, which was extremely troublesome, but in the cleaning material for an automobile body of the present invention, only one side of the clay layer is exposed. The film can sufficiently prevent it from drying.
