Green corrosion on atari cartridge contact pins

Its the result of copper oxidation. Copper is used to form the tracks on the PCB and is gold coated for the cart's contacts. Try removing it with ultra fine grit sandpaper e.g. 800 or 1000 grit.

 

In some cases I've seen the green stuff in powder form. And it takes nothing more than some toilet paper to remove it.

Well there's different grit for nail files also.Yeah, i'm going to stop using any type of sandpaper and just scrub away with alcohol.I think repeated sanding with any grit number paper will chew away the contacts and make loose connections?, that's what i figure.
