Try to never allow potassium permanganate to soak into the clothes and dry it. Immediately after the formation of stains liberally fill it with curd or whey. Give the contaminated clothing to soak in this liquid for about 4-5 hours. Make sure that the stain of potassium permanganate was constantly in the serum.

Arrange home chemical mini-lab, if you bring the stain of potassium permanganate listed methods, you failed. Chemists or photographers get not only sodium thiosulfate but also a little sulfuric acid, or potassium metabisulfite. Your task is to slightly acidify the fixer.
