which evaporates faster, 70% ethanol or 90% isopropyl?
Also, what happens if I mix acetone with either ingredient? I want to make my own homemade hand sanitizer, a mix between fast orange type solvent degreaser and regular germ killing alcohol based hand sanitizer. Acetone is the only off the shelf solvent that I can think of adding. I'll skip the pumice powder.
This is what I currently do. I use hand sanitizer to kill the germs, and then I used a solvent(pic related) to dissolve the oils on my hand, then I use a paper towel to wipe my hands dry. There's nothing I hate more than getting someone else's grease on me. Like touching a greasy doorknob or shaking a man's hand. I heard that oily substances are the number one way that germs are able to stick to your hand.
