Instructions
Mix equal parts isopropyl alcohol and water in a small container. Dip a cotton swab into the alcohol solution, squeezing out any excess.
Clean the contacts on the bottom of the cartridge with the cotton swab. Clean the metal and the plastic on the inside, using new swabs until they come out clean.
Dampen a cloth with warm water and 1/4 tsp. dish soap. Wipe the outside of the cartridge with the cloth to remove any dirt or residue. Use the alcohol solution to remove glue from stickers or labels. Rinse the cartridge with a clean, damp cloth.
Dry the outside of the cartridge with a clean cloth. Allow the contacts to dry for 10 to 15 minutes before playing.
