Cleaning small sections of boards from flux


New member
Hello guys, usually after a successful repair I drop my board into the ultrasonic and clean away all the shit.But what about small repairs or quick ones? What is the best way to clean the board from the flux?
I usually use alcohol/Butanone with ear cotton picks and... a glorified toothbrush....

What would be the best way to clean away that shit? Thank you


In most cases I just leave it on there. But acetone and a toothbrush works fine for me. Alcohol is just too mild and takes a lot of effort to get flux off.
