I used it for washing machine cleaning and it did a good job. I had tried before with chlorine and the usual vinegar with baking soda, but this removed an unpleasant odor from the washing machine in one go.

After several tests on various products, I concluded that this is by far the best. It eliminated all the odors from the washing machine, while previous detergents I used persisted. Amazing product from the very first use. The manufacturer recommends two uses that the product has, but from the very first use, it eliminated the odors and cleaned my washing machine, making it shine. I mention "washing machine" in parentheses because the product itself is promoted by the English for cleaning kettles.
