Universal Game Cartridge Cleaner 3 Card Pack by 1UPCard

These are an absolute must have for old school gamers and game consoles-games etc.Extremely hard to find but truly worth paying for them if you can get any. These and the cartridge cleaner are highly recommended

As a retro gamer and collector I always need something to clean my cartridges with and even though a Q-tip and alcohol works just fine some games just need something a little better and thats where these come in handy, price wise they are a little pricey for what they are but could be used many times before being tossed out. Highly recommend these.

Excellent cleaning felt on these cards, works great with 99% isopropyl, and the dry side buffs the pins on cartridges very good.

Terrible product cleaning pads peeled off after a couple of uses. Over rated product

There are 3 cards per pack. Each one is a credit card-like piece of plastic with two strips of plastic scrub pad. Soak one strip with alcohol, then scrub at the contact pins of the cartridge. Then buff with the dry strip. Wait a while for the alcohol to evaporate. Simple, and it works great for cleaning stubborn carts.

I am cleaning up the contacts on my son's (almost) forty year old NES game cartridges before boxing everything up and sending it to him. Most of the game cartridges will not work after years in storage. With a little scrubbing of the contacts using one of these cleaner cards and some 90% isopropyl alcohol, they work great!!
