Is it also safe to use on the top of the board? Is 91% good enough?The standard solvent used for cleaning PCB is 100% (or close to it) isopropyl alcohol.

Isopropyl alcohol is used for cleaning flux residue after soldering. It is safe to use on top of the board.Is it also safe to use on the top of the board?
Isopropyl alcohol is usually specified as 99.x% and not 100% because it is hygroscopic. I think it's best to get the "100%" kind. With a 91% solution, the other 9% might not evaporate and leave residue instead.Is 91% good enough?

Isopropyl alcohol is made without water, only alcohol. But we are in planet Earth and the air has water in suspension (% relative humidity) so you use it in the air and the alcohol takes the water from the air, open the bottle and use asap . Can not have 100% alcohol in air in planet earth.
