If you search, 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. :-) Len Anderson retired (from regular hours) electronic engineer person |
