I live in CA and it's 2018 and for some unknown reason here in California are government without voter approval decided drinking anything stronger then 120 proof is a NO NO so this just happened a couple months ago all the vodka stronger then 120 proof was pulled off the shelves. Here is the problem, in order to clean a coil and actually get it clean you need at least 75% by vol alcohol which means you need 150 proof vodka or stronger well you can't get that here in the golden state anymore and I no you need 150 proof because I used it before and it works great and I've tried 120 proof and it doesn't work very good at all it hardly removes anything. So my dilemma is should I try 91% rubbing alcohol which is the strongest alcohol you can get for drinking or rubbing. What I would like to know is what's so dangerous about using it to clean coils. I know it will kill you if you drink it but I'm not drinking it, I'm cleaning a coil and rinsing most if not all of it off and out of the cotton
