I simply use products from Kontakt Chemie.
Kontakt LR = Kontakt PCC for chemical and mechanical cleaning (flux
residuals, water, dirt), afterwards Plastik 70 for sealing to avoid
corrosion, oxydation, leakage currents.
Good ventilation during application is important for all solvents, which
have a good cleaning effect.
They all are poisonous and evaporate easily.
To my experience, propyl alcohol is not strong enough, and acetone may
harm PCB and components.
The additional mechanical cleaning by a brusch helps a lot.
