The cleaning products according to the invention have the following advantages:

- through their modular structure, there is the possibility to manufacture a large variety of 25 solutions, for universal cleaning, in the household and in the professional field, as well as for specific cleaning, by simply combining the respective modules in different proportions; 30

- the small number of substances in these modules makes the manufacture of products much simpler than the known ones, with many components;

- the substances used are well tolerated by the environment, being disintegrable in proportion of at least 90% and not harmful;

- the cleaning is effective and fast, and in the case of metal cleaning the products 4 are more efficient than the known ones, they can be used in cold, hot and high pressure, as well as in all the processes of combined metal cleaning;

- reduce the pollution level at the wastewater treatment plants.

The following are four examples of making the products according to the invention.

Example 1. Dissolve 5 to 5 or 15 parts by weight of a (C1 2) benzenesulfonate alkyl (preferably sodium) in 95 to 85 parts by weight of demineralized water by mixing at 30 ... 40 ° C until the solution it becomes clear. The anionic module is thus obtained. Separately, they are introduced into demineralized water O up to 0.2 parts by weight, generating complexes, preferably ethylenediaminetetraacetic acid (EDTA), nitriltriacetic acid (NTA), (o-carboxymethyl) -malic acid (CMOS) or poly (tetramethylene) acid. 1,2-dicarboxylic acid (EMA), 10 to 20 parts by weight of ethoxylated fatty alcohol preferably C10 and having 5 ethoxy groups, or 3 ... 7 ethoxy groups, 5 to 10 parts by weight of 10 alkoxylated fatty alcohol ... 18 C and preferably with 2 ethoxy groups, 2 propoxy groups and 1 butoxy group. The amount of water is such that the mixture is 100 parts by weight. Stir until the solution becomes clear. It represents the nonionic module.

Mix 1 to 55 wt. Weight of diethanolamine in 99 to 45 wt. Of propylene glycol until the solution becomes clear. It represents the module to facilitate solubilization, but can only be represented by 100 parts by weight propylene glycol.

To achieve a universal cleansing concentrate, mix 26 to 27.5 parts by weight anionic mode solution with 60 parts by weight nonionic mode, 10 parts by weight how to facilitate solubilization and 2.5 to 4 parts by weight of aromatic oil, all in water (preferably demineralized) added up to 100 parts by weight solution. This is used to remove dirt, oil and grease residues, in the case of daily cleaning problems that occur in household and production. It cleans doors, containers and shapes for baking, faience and tiles, lacquered surfaces, tools, refrigeration rooms, cars, scales, bathtubs, pots and the like.

The universal concentrate is added in an amount of 5 to a maximum of 10 ml per liter of washing water in case of normal cleaning problems. If using a carrier (cloth or fur coat), put 2 to 3

RO 112759 Droplets on it, wetting the carrier with a little water and cleaning. It is then rubbed to dry.

Example 2. Prepare the solutions representing the anionic, non-ionic and solubilization module as described in Example 1. Mix 27 to 35 parts by weight anionic mode with 55 to 63 parts by weight nonlinear mode, 9.8 to 9 , 95 parts by weight and one solubilization mode and with 0.05 to 0.2 parts by weight anti-corrosive substance in water (preferably demineralized) added up to 100 parts by weight concentrated solution. 15 This is used for cleaning metals, including aluminum. Due to the corrosion inhibitor it can be used in the case of hot metal baths (neutral pH).

Preparation of cleaning solution 20 depends on the conditions of use. Thus, when used cold, mix one part of concentrated solution prepared as above in 1, 2 or 4 parts water (in the case of dirt containing 25 oil or fat the concentration depends on the degree of dirt). When used hot, mix 1 part concentrated with 4 ... 19 parts water. The solution thus prepared is applied to the metal surface 30 to be cleaned (ie sprayed) or the parts to be cleaned are introduced into the cleaning solution. After leaving time for its action (depending on the degree of dirt and how it is applied cold or hot), it is cleared with water.

In case of use for high pressure cleaning, mix one part concentrated with 19 ... 49 parts water. For single-phase cleaning, the cleaning solution is introduced and applied according to the high pressure cleaning instructions given by the manufacturer of the cleaning product. For cleaning in 45 two phases, the cold cleaning solution is applied on the surface to be cleaned. After an action time (depending on the degree of contamination), continue with the high pressure cleaning solution 50 (a concentration of 1:49 being sufficient) as with one phase cleaning, according to the pressure cleaning instructions given by manufacturer.

Example 3. Prepare the solutions representing the anionic, nonionic and solubilization module as described in Example 1. Mix 10 parts by weight the anionic mode with 10 parts by weight the nonionic mode, 10 parts by weight the solubilization mode and with 0.4 up to 1 part by weight of aromatic oil in water (preferably demineralized) added up to 100 parts by weight concentrated solution, which is used for special cleaning of computer cases, for removing dirt, oil and grease residues from the polymer layer of computers, monitors, printers and other peripheral devices in the electronics industry.

Spray the cleaning solution on the surface to be cleaned with a regular spray, or use a cotton cloth moistened with solution and apply it on the surface to be cleaned, in both cases taking care to cover it as fully as possible. After a short time of action (usually 6 to 10 seconds at normal dirt), in the second stage of the process the surface is wiped until it dries. No other cleaning steps are required.

Example 4. Prepare the solutions representing the anionic, nonionic and solubilization module as described in Example 1. The preparation is done in usual containers. Then mix 10 parts by weight anionic mode with 10 parts by weight nonionic mode, 10 parts by weight the solubilization mode, 0.02 parts by weight anti-corrosive substance and 0.4 to 1 part by weight aromatic oil in water, preferably demineralized, added in such an amount as to result in 100 parts by weight solution. This is a special cleaning product for jewelry and jewelry that removes dirt and grease residue from them. It also cleans the metal bracelets of the watches (at watches) and is used as a load in the ultrasonic baths of the jewelers.
