Picture of How to Clean your GameBoy Game Cartridges
So eventually you will go down to your basement, and look through all those boxes full of old electronic gadgets and gizmos. And eventually you will find your old, brick GameBoy. Boy, was that thing fun to play! Killing time while waiting in in line for the dentist, in the bathroom, grocery lines, commercials on TV, what ever it was. You pop in a game into the old brick in your hands, and slide the power switch to on. BOOM! ....... I said BOOM! ........... A pixelated Nintendo Logo comes scrolling down from the top of the monochrome screen. Now thats why you need this Instructable!

(Please remember that I take no responsibility if you screw up your Game Cartridge!)

For this quick & easy project, you will need the following:

- Nintendo GameBoy Cartridges (Any kind will work. I am using Original GameBoy Games for this demonstration) 
- 1 to 2 Q-Tips
- A Cup of Water 

Step 2: Prepare the Q-Tips

After you are done gathering all your supplies, dip one side of your Q-Tip into the cup of water. Repeat this process 2 to 4 times. Make sure your Q-Tip is only slightly damp, or the water will damage the contact pins on your Game Cartride

Step 3: Clean, Clean & Clean

Once you completed Step 2, take one tip of your Q-Tip and dip it into your Cartridge. Make sure the tip reaches all the way till the end of the plastic. Now evenly "spread" the tip throughout the whole cartridge, till you reach the end. Repeat this process 5 to 7 times.

Step 4: TEST!
