So, I've cleaned it with a toothbrush and then alcohol next, and tested the resistances. The resistances are just a bit lower than what they should be. Is this bad?Swooshes like that definitely make for a possibility between shorting of multiple layers, best thing you can do right now is check your resistances as per this guide:
I'd also recommend using a dry toothbrush to clean up the board a bit, then use some IPA and a paper towel to finish it off.
In my 3 trims, the resistance values were different than the values on the post, even I saw two different values between 2 trims of the same board revision.So, I've cleaned it with a toothbrush and then alcohol next, and tested the resistances.
