How to properly choose a detergent for molds in order to effectively clean them from mortar

Molds used for the manufacture of various concrete products, despite being lubricated before pouring to prevent the mixture from sticking to the inner walls, still need to be cleaned of concrete residues after several cycles of use.

Hardened mortar can be removed mechanically using tools, but it is best to do this using a special detergent for molds presented in our online store. Thanks to it, molds made of any material (metal, plastic, polyurethane, fiberglass, etc.) can be effectively cleaned of lime, concrete, and cement plaque.

Since STROYTEKHNIK specializes in the sale of plastic molds, let us consider how best to restore them to their original appearance using a cleaner for plastic molds.

Chemical composition of cleaning solutions

The composition of any mold detergent contains chemical components. These can be solutions of:

1. sulfuric acid;
2. hydrochloric acid;
3. special solvents.

The choice of a detergent for plastic molds depends on the task at hand:

• removal of old deposits;
• cleaning of fresh plaque;
• the type of remaining mortar (cement, lime, or other).

Pros and cons of detergent for plastic molds

The advantages of cleaning agents include the following qualities and properties:

1. fire safety;
2. does not damage the mold surface;
3. short time required for effective cleaning;
4. rapid evaporation from the mold surface.

The disadvantages include the chemical aggressiveness inherent in concentrated acids, so it is necessary to take precautions when working with cleaners – use protective gloves, carry out the process in the fresh air, and know how to act if the product gets on the skin.

How to use detergent for plastic molds

The principle of operation of the wash is the gradual penetration of the product into each layer of mortar hardened on the mold, which destroys its structure, thanks to which the mixture residues gradually peel away from the mold.

The detergent is available in two forms – concentrated and diluted.

Concentrated wash is better because it allows you to independently dilute the cleaning solution to the required concentration depending on the level of mold contamination.

The cleaner for plastic molds prepared in the required proportions for use is applied to the surface with a brush, sponge, or spray bottle.

If you need to clean a large number of molds, it is recommended to use containers (baths) resistant to chemical reagents for washing, into which the detergent is poured and the molds are placed.

The contaminated mold is pre-cleaned (if possible) of debris and large fragments of the hardened mixture mechanically and only then poured over with the solution.

After the time specified in the instructions for use of the specific detergent has elapsed, the foam formed as a result of a chemical reaction is washed off abundantly with a stream of water, preferably from a hose.

In case of heavy contamination, when it is not possible to clean the mold the first time, the procedure is repeated.

The online store "Stroytekhnik" sells detergents for molds in 50-liter plastic barrels.
