The best way to clean your carts is to open them up so you can really go to town on the connector blade. The tricky bit is getting your hands on a tool that’ll let you open your cartridge so you can give the connectors a serious scrubbing. The tool you’re looking for is a 3.8mm security bit that’ll work with the special screws on your NES games. It’s sometimes called a gamebit, and you can easily find one on sites like eBay and Amazon.com for about $6.00.

If you get your hands on a security bit, open your cartridge and take the game board out. Then, just give the connector blade a rub with a pencil eraser. It’s that simple. Wipe off the eraser bits when you’re done. You can also go over the connector with a Q-tip dipped in rubbing alcohol. Wipe off any remaining residue with your cloth rag.

If you can’t get your hands on a security bit, it’s tough to clean the connector blade with a simple pencil eraser. However, you can still clean the blades with some Q-tips, Brasso metal polish, and isopropyl alcohol. Apply the Brasso to your Q-tip and apply the polish to both sides of the blade. Continue swabbing the blade on both sides. Next, go over the blade and surrounding area within the lip of the cart with a Q-tip dipped in alcohol several times to remove any residue from the Brasso. Finally, just go over it one last time with a dry Q-tip to remove any residue from the alcohol.

Cleaning your carts is only the first step in getting your NES to play games properly again. It doesn’t matter how clean your carts are if the inside of your NES is full of dust bunnies and cat hair. Also, the 72-pin connector, the part that connects with the blade in your games, is notorious for wearing out. So we’re going to walk you through the process of opening upthe console so you can clean it up and replace the 72-pin connector.
