SNES and N64 Preservation

[Joelius]

I am new to the classic gaming industry, and i was wondering what would be the best way to preserve my SNES and N64 games and systems. I know the games for the SNES at one time came with plastic covers for the carts, but is there something out there to do or use to keep them in top notch shape?

Keep em dust free, clean the connectors with oxidizer solver and dont leave the games in the machines if your not playing.
