How to make a defoamer for a vacuum cleaner with your own hands? How to replace defoamer for a Karcher vacuum cleaner?

The defoamer performs an important function - it prevents excessive foaming, thereby preserving the engine and filter. Typically, professional products are used for these purposes. But if you don’t have them on hand, you can make a defoamer for a vacuum cleaner with your own hands. Proven recipes are described in this article.

Purpose of the defoamer

The defoamer is a liquid composition or a product in powder form. It contains substances that destroy the foam that forms when the vacuum cleaner operates in wet mode. During operation, small dust particles fall into the soap solution, which causes the foam to significantly increase in volume and interfere with cleaning.

To prevent this from happening, use special means of 2 types:

• with silicone base;
• with organic oils.

The former are cheaper and they are more popular; the latter are more expensive. Therefore, the problem arises of how to replace the defoamer for a vacuum cleaner. Instead of special preparations, it is quite possible to use improvised means that effectively prevent excessive foaming.

3 ways to make your own defoamer

It is clear what a defoamer is and what functions it performs. This composition inhibits the formation of foam and thereby protects the filter and engine.In addition, it provides stable power with which the device operates. In practice, 3 recipes are used that allow you to prepare the defoamer yourself.

Salt

To prevent the formation of excessive foam, you can use regular salt. It really interferes with these processes, which was tested using the example of Fairy dishwashing detergent. Just add a little salt to the water in the container and stir. This is a good analogue of the defoamer for Karcher vacuum cleaners and other brands.

Sunflower oil and soda

Instead of salt, you can use sunflower oil and baking soda (a tablespoon each). This is a very effective method, but after cleaning you will have to clean the container from grease. This can be done using regular dishwashing detergent.

Vinegar

Another do-it-yourself defoamer is regular food vinegar with a concentration of 9%. It is enough to take half a tablespoon and pour it into a container. You can also use vinegar essence 70% - a few drops are enough. Be careful when doing this, as the solution has a pungent odor.

Preventive measures

Now it’s clear how to replace the defoamer for a Karcher vacuum cleaner or other models. At the same time, you can follow a few simple rules that will prevent excessive foam formation:

1. It is enough to change the water in the container quite often - this method is suitable only for small rooms that do not require large-scale cleaning.
2. Carry out cleaning at minimum power, while opening the cap on the handle. After dust collection is completed, further work can be carried out at maximum power.
3. Fill the container with a small volume of water - a maximum of one third.However, you will have to constantly monitor the level and add water if necessary to ensure stable operation.

Thus, it is better to carry out cleaning using a defoamer. Professional products are added to a container of water in small quantities according to the instructions. If they are not there, you can use any of the described recipes.
