Solder on gold LCD pads | 5 October, 2001

I have had an issue where solder has contaminated gold plated pads (fingers) where it is not acceptable. The pads must remain perfectly coplaniar for a LCD zebra strip to lay accross them. Does anyone know of a way to remove the marriage level of solder (tin/led) from the pads without damaging the circuits on the PCBA? I have looked into reverse electroplating, but I have concerns about pumping current into the board.
