My A button was requiring a harder press for the input to be registered than normal, so I opened up my GBC and noticed this transfer on the PCB. I guess years as a child hard holding A to improve pokemon catch rates had caught up. What’s the best way to remove this? Isopropyl alcohol and cotton bud?
It’s not straight up water. It’s water and other chemicals. These chemicals leave a residue that can be corrosive.
Pure 99% IPA shouldn’t leave white traces on the board.
