Ordinary rubbing alcohol has 70% alcohol and 30% water in it. If you

some drug stores carry 90% isopropyl rubbing alcohol.

This stuff is getting pretty rare, but it would be preferable if you can
find it. I used to see 99% isopropyl alcohol but haven't found any for
years. I keep looking, though.
If you want high-proof isopropyl alcohol, you need "reagent grade"
stuff which is available from chemical supply businesses. Clean
room assembly places buy the stuff in bulk. Some medical supply
places have it, too.
When using isopropyl the next thing needed is cotton swabs...lots
of them (on wooden sticks), another expense item. :-)
