SHTFriday: Potassium Permanganate

I finish up Blue Collar Prepping's first ever theme week (water purification) with a discussion about one of the many uses of Potassium Permanganate.  Seriously guys, this is like the Swiss Army Knife of chemicals.


Actually, just read the entire week, especially if you live in Ohio or Michigan. Or Utah, for that matter.
