Best way to clean iPhone XS Max logic board?
I recently purchased an exploded iPhone XS Max and managed to remove the logic board. Unfortunately it was covered in carbon particles so I put it in some 99.9% isopropyl alcohol for about 20 mins and used a toothbrush to try and clean it. It hardly worked at all and now I’m kind of at a loss for what to do. Do I keep trying the same thing over and over again? Is the board already beyond repair? Thanks for the help!
