Potassium permanganate is a strong oxidizing bleach. Potassium permanganate sold in stores is usually a purple liquid or crystalline substance. Many decontaminators know that this type of bleach should be used with caution as it can cause dangerous reactions to fabrics and pigments. But in practice, the bleach is no more dangerous than sodium hypochlorite, titanium sulfate and sodium sulfite. This means that if potassium permanganate is used in the right way, risks can be avoided and good results obtained. Of course, you need to test it before you use it.

Potassium permanganate, which removes residual streaks of color, ink stains, stains and mold stains, can replace sodium hypochlorite, which cannot be used on wool or silk fabrics. However, like other strong bleaches, potassium permanganate can react with fluorescent dyes, so even white fabrics need to be tested.
