I've frequently passed on the advice to check the capacitors in the hand held 80xx meters (8020, 8060, 8024 et al) both "A" and "B" versions, but, embarrassingly, I've found some that I neglected to check. (Most of my meters had capacitors that weren't leaking yet, or were so far gone I didn't bother repairing them.)
I got one meter in time, but there is some electrolyte on the board that has discolored the tinned traces. Forgive me if this was mentioned before and I missed it, but what should I used to clean this electrolyte and ensure that the residue won't continue to corrode the traces? I've used ethanol on cotton swabs and the dreaded fiberglas pen. (which I understand some swear by, some swear at)
I don't want to replace the capacitors and still have a problem, so if anyone has any advice, I'd appreciate it.
