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?

    Even 91% seems quite impure, it will leave a lot of residues on the board. Best to go with 99% IPA

      Alcohol is so hydroscopic that your 99% will be 91% pretty quickly after opening. 91% is fine, even 70% will do, it just takes a bit longer to evaporate.

      The “impurity” is straight up water.

        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.
