Acetone... You exagerate!
Nope! I know it's quite harsh, and I wouldn't recommend anyone use it without knowing what's on the board, but I've found that SMD chip components and the hard plastic semiconductors are quite resilient to it. I wouldn't soak the board, but a quick splash doesn't harm anything, and I've done it loads of times with good results. I do keep it well away from "open" items like trimmers and soft plastic like connectors.
Pink alcool is the one you found in every supermarket, the one for clean stuff...
I've never seen that. Is it actually dyed pink?? All the alcohol I see is clear.
Oh, acetone dissolve some mark on resistor...
Not in my experience. TBH, I wouldn't care if it did. I can hardly read them at that size anyway...
