Aloe oil and denatured alcohol is a formula I found on the net. Rubbing alcohol is the same thing but with water added. You can look up the proportions or experiment (strength) to fit your taste. I haven't figured out if it's cheaper yet but I'm betting it is.
Anyway, here it is if you wish to make your own.
Wow. That stuff seems a tad strong. Hydrochloric acid may be a better choice. The formula I found also mentioned glycerin but the aloe may be better on your hands.. maybe a little of both.
The vodka would be good to drink... right before you die, I suppose.
