Every 2 months and it has made a big difference in the washing machine. Firstly, it removes that damp smell that a washing machine can have, as well as the dirt that accumulates in the pipes. The difference is immediately noticeable in the clothes

I used it exactly as the instructions said (which you needed a magnifying glass to read). As soon as the washing was finished, the washing machine smelled even worse. It was as if I had unwashed clothes inside for a month. I would enter the bathroom and the whole bathroom smelled bad. And the clothes I washed afterwards didn't smell fresh. Then I followed the classic method with baking soda and vinegar and the washing machine returned to normal. I definitely do not recommend it.

Unbelievable product! After each use, it makes the washing machine shine with cleanliness in the drum and on the door seal. The seal itself needs to be wiped with a dry and clean cloth after each wash, not letting it darken first and then waiting for dettol to work miracles!

Using it for the first cleaning that the application requested (Hoover washing machine via the hOn app), it created incredible odors on the clothes. After drying, they smelled like mold, as if they had been forgotten inside the washing machine for days. Stay away.

The best thing for washing machine cleaning instead of "playing" with vinegar and baking soda. It cleans AND disinfects. Just make sure to find it around 3.5 euros and not buy it for around 5 euros.

Personally, I also use it in a water air cleaning device (VENTA) in a minimal dosage so that the water that cleans the air doesn't have any suspicion of bacteria after a few days.

In the washing machine, it works well for about 40 uses. They say once every 2 months if you use the washing machine EVERY day.

The other person says that in a 10-year-old washing machine it did nothing, if you have never cleaned a liquid it will not work miracles, the washing machine needs regular cleaning and from us in the door seals, in the filter, etc.
The product is excellent and does a very good job.

Wonderful lemon scent, easy to use, you simply empty it into the detergent drawer and run the washing machine at 60 degrees without clothes, of course, and the washing machine smells clean. I will definitely buy it again!

Application in 2 washes in a washing machine without any particular smell, the result was that the whole bathroom smelled like rotten eggs and mold, wasted money. The best disinfection from odors and bacteria is done with baking soda and white vinegar
