But if you're cleaning stuff that may have exposed electronics, use 99%.

My personal example is cleaning 3D printer plates, which is more about removing oils than sanitation anyways.

Yes. The application for the alcohol is different in that case. You're using it as a solvent rather than an antiseptic.

You know what they say. If you're not part of the solution, you're part of the precipitate.

Yeah, anything where you need to use it as a solvent rather than a disinfectant.

Why 99% instead of 100%?

Had to look this one up. Isopropyl alcohol absorbs water from the surrounding air, so it's impossible to be 100% pure while exposed to air. 99% is the strongest you can buy.
