careful. I've never used it on PC boards before, but it can't be beaten

So what can you do with accumulated mineal salts around component
legs? Looks like tin "rust". I tried firm-but-gentle with a stiff
toothbrush, and didn't get anywhere.
I have that MV3100-90 board that I think just needs the corrosion,
which I suspect is conductive, removed.
