I can always find 90% isopropyl alcohol at my local Walgreens drug
emporium or
at the Safeway supermarket. I'm quite sure that this material is widely
available.
A 16oz bottle is worth about a dollar.
The stuff is water clear with no additives. I also see on the shelves a
"Rubbing Alcohol" that is tinted green and it contains some other
ingredients, perhaps wintergreen or some such.
I've been using 90% isopropyl for many years as a general purpose
cleaner.
It is relatively safe, although flammable, and the fumes are
not too nasty.
