Hey Guys, I know 99 percent Alcohol is safe and very affective to clean pcb's and flux. For acetone however I have heard mixed opinions. Since in my opinion acetone is cheaper, is it safe to use it to clean off corrosion and or flux off of old pcb's.

P.S. This acetone is the glue remover type and not the weak nail polish remover.

Thanks, Kuljot Dhami

Acetone works OK but leaves the aroma behind. Since acetone is a little oily, it can also affect contacts and get into some things and make a mess. Many plastics do not handle it either. The best stuff I can think of for cleaning PC boards is a fluorocarbon that can be an issue with the EPA. (R-11 freon). Unless you have a way of capturing it and re-condensing it, I wouldn't recommend it.

The canned electronics cleaners that contain 1.1.1 trichloroethane (or TCE) works well. It also attacks some plastics but it does nicely on boards.
