So Ive been a user of 91% Isopropyl (rubbing) Alcohol for various purposes for several years now and recently made the mistake of purchasing 70%. I had forgotten how weak this variety was and was disappointed when a strong aroma did not pierce of air when I opened the bottle. Furthermore, Im afraid that because it wont leave extremely dry skin behind that it is in fact not really "working". I have to see it to believe it! And I want to see the bodies of dead germs everywhere including collateral damage to supple skin surface. Does it matter to you either way what type of alcohol you use? Or are you an indifferent middle of the road type, just going through life in a happy-go-lucky fashion not really caring if the job was done or not?
