For rubbing alcohol that is. It is hard to find at the store. And when they do have it, it is 50% alcohol. I'm not sure that would kill anything. I looked at ebay for it and nearly fell over. I used to buy the 91% alcohol, (because they quit selling the 99% stuff) and it cost me under $2.00 at walmart for a 16oz bottle. On ebay I seen the stuff going for around $20.00 a bottle.
I tried to buy some denatured alcohol at walmart. Thinking "denatured" meant they removed something from it. It turned out to be the opposite. When I got it home, I smelled it and it didn't smell right. So I looked it up and found out that "denatured" was corporate lingo for "poison added." I guess "denatured" just sounded better. Apparently they add methanol to make it poisonous to drink. So I took the crap back.
