It’s ethanol. The same denatured alcohol my grandma used to do the final step of window-cleaning with. I have Isopropyl as well, but I use that sparingly since I can’t just grab another bottle of that at the supermarket. So for me it’s simple ethanol for the cleaning and I’ll dump it in the windscreen wiper tank of the car (mixed with water). And the Isopropyl is for cleaning electronics and PCBs. And I’d have to look it up, but I think it’s way more pure than 70%… It evaporates from the PCBs after a few seconds with no residue… The ethanol from the supermarket doesn’t do that. And I wouldn’t expect 30% of water to evaporate that quickly either.
Isopropyl really is a godsend, though. Someone will dump a glass of apple juice or Coca Cola into my TV remote control… And after 15 minutes of ranting about how no engineer uses screws anymore, I’ll somehow get the thing open, and thanks to the alcohol it’s good as new a few minutes later.
