This. Also methanol, but I’d much rather use isopropanol. I know higher proof (>70 %/140 proof) ethanol also works.
But isopropyl is the best/easiest. Just don’t drink it…or methanol at that.
Also anhydrous ethanol ~99 % ethanol, as it contains benzene or other things you don’t want to consume.
That’s how the ancient knowledge of the lab gets passed down. Well, ideally before you leave. Gotta teach the new generation.
