Is Isopropyl Alcohol Electrically Conductive?

Alcohol (isopropyl alcohol, ethanol and isopropanol) is a polar solvent (very conductive) and is potentially corrosive (contains water).

Is isopropyl alcohol safe for electronics?

IPA 99% is safe and effective for consumer use to clean personal computers and electronic devices. Isopropyl Alcohol 99% is the best substance to use for this purpose. Isopropyl Rubbing Alcohol 91% may also be effective, but it is best to use the purest IPA available.

Can I Use It to Clean My Devices? It’s best to avoid using any isopropyl mixture below 90% on circuit boards and other electrical bits. If you’re simply cleaning the adhesive off something metal or plastic, 70% might do in a pinch, but you’ll want to be sure not to spill it onto circuits or wires.

Why is isopropyl alcohol not conductive?

Pure Isopropanol does not conduct electricity because it contains covalent bonds and does not ionize to lose free electrons to conduct electricity. However, a solution of 70% alcohol/water can be electrically conductive as water portion. So, pure alcohol does not conduct electricity.

Isopropyl alcohol itself is not conductive. A 70% alcohol/water solution will only be as conductive as the water portion, inhibited somewhat by the alcohol. It is conductive enough to worry about, though, so don’t run the electronics involved until they’re completely dry.
