Last resort for destroyed card-edge fingers
If the fingers on a single-sided edge are ruined, drill 1/16" holes through them, push .110" Molex header pins through from the plain side at a right angle, glue the pin strip on and solder the pins to what is left of the fingers. Cleaning or replacing the connector is far better.
