APPLICATION
Add about 200 g of washing powder to a bucket of hot water.
Dissolve a small amount of potassium permanganate in a glass of water. The water should turn out slightly pink.
Stir until the crystals are completely dissolved. Potassium permanganate should not be added directly to the bucket so that undissolved crystals do not leave stains on clothes. Pour potassium permanganate from the jar into a bucket.

Place already washed white items in the bucket.
Cover the bucket with plastic as tightly as possible and wait until the water cools completely. Then rinse the clothes thoroughly
