Isopropyl alcohol removes oils, adhesives, fingerprints, soldering flux and other contaminants, making it ideal for cleaning electronics.

For externals – such as disinfecting your smartphone or TV remote – 60-70 percent will do a better job.Not all electronic components are compatible with isopropyl alcohol cleaning, however.

Is 91% rubbing alcohol conductive : Isopropyl alcohol itself is not conductive. A 99% or even 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.

Will alcohol damage the CPU : Yes, that should be fine. Really it's more important to not use something like a paper-towel, or napkin to clean it because those can tear and leave little pieces of paper residue on the CPU.
