I know this is an old thread, but David (or anyone else?) would the potassium permanganate be effective enough on its own to sterilize tools? (with the dip in the 70% rubbing alcohol to destroy the P.P. so as to not stain everything ~as David C. mentioned~)
I'm looking for something that travels (8 hours in a car) better than a blow-torch (at least for this coming summer... After that, I have an acetylene blow torch that I'm perfectly comfortable using)
