I was recently introduced to this great product created by Adam Stephey called the 1 UP Card. This is a great and easy product that can work on NES, SNES, Genesis, Atari 2600, N64 cartridges and more.
Here’s how it works:
Moisten end of card that reads “Fluid”.
Scrub game board with now moistened end.
That’s it! The 1 UP Card is also great for removing stickers and permanent marker.
So check out the 1 UP Card to keep your games clean and help extend the life of your cartridges. The 1 Up Card is available at: http://www.1upcard.com.
