I used alcohol to clean board, and then before reasembly used a small amount of armorall on a soft cloth to make the board not be chalky white looking. not that the appearance is the issue I just assumed it probably would not have any possible oxidization with the use of this. and this was done on a portable dvd player, which had been outside in the rain and snow of the winter months without my knowledge of it being there. the board actually had rust around the volume wheel and couple other places but worked perfect after little tlc, I have fixed many things since this one with the same products. : ) Not sure if anyone will even read this being year since last post but heck I suppose I am here reading the previous so chances are possible.
