Using a small area of the board where you could correct any damage
that this substance might cause, try a little CLR... it's a mixture
sold throughout the midwest (U.S.) that dissolves Calcium, Lime, and
Rust deposits. Phosphoric acid is one of its components... so be real
careful. I've never used it on PC boards before, but it can't be beaten
for removing corrosion off metal parts.
