99% isopropyl alcohol is ideal as a solvent or cleaning agent for industries that produce water sensitive items, therefore rapid evaporation and low water content is favorable. 99% USP IPA provides the lowest presence of water and in some forms is free from denaturants. Computer technicians, medical device manufacturers, printed circuit board manufacturers, and soldering and rework technicians prefer immediate evaporation for work with sensitive devices such as integrated circuit adapters, computer chips, and circuit boards. 99% IPA evaporates cleanly and minimizes residual substances. Rapid evaporation reduces shelf life but is more effective against sticky residues, grease, and grime than 70% concentrations. Because isopropanol is hygroscopic, acetone may yield better grime fighting results for inks or oils.
The URL you shared recommends using 99% IPA for electronics.

Okay. This isn’t about disinfecting. This is about electronics safety. The higher the better

I was almost surprised at the ridiculous reply, then I realized it was from a moderator, and it made a lot more sense.
