i may be confused, but is potassium permanganate the main active compound in some of the powdered, industrial strength drain-clog products? i was having a hard time remembering the exact name of the chemical, but thought i had found it next to the draino at home depot. IIRC it was a green powder. i had no use for a 5 gallon supply, and because i wasnt 100% it was the right stuff i didnt buy it. any ideas?
