Be careful using isopropyl alcohol. You don't want the dissolved Flux flowing
inside switches and under components. Then the alcohol evaporates and the Flux
stays inside. .not good.
This is why the industry has largely switched to no clean flux. Just leave it
alone.
Of course you have to know what you're using.

99% Isopropyl alcohol is the approved solvent for getting flux, et al
off boards... It evaps rapidly and is water soluble...
