i have a quick question about electronics
i have a pcb that suffered corroded traces /components mixed with dust
i used isoprophil alcohol many times with a toothbrush and the corrosion is still there acumulated on the small soldering of the small components
then used rice vinegar for some minutes and wash after that with alcohol, and corrosion is still there.
the only way I managed to clean some of the small smd components like resistors and smd capacitors was scratching slowly with a needle. but that cleans it but not fully and its a very slow process.
is there any other way to clean corrosion left on soldering?
( green stuff is minimal but sometimes you cant remove it fully and..im talking about what corrision does to soldered components when the soldering is not shiny..and looks pale and acumulates a lot of god knows what..dust or whatever it is that if you scratch with a needle on the soldering it starts to clean
see a toothbrush does nothing when i use it on an smd resistor...the two sides of the soldered resistor never gets fully cleaned
