I LOVE NES games, and there were some cheap ones that I've thought about picking up on eBay. However, one of the people that I live with is definitely high-risk, and I don't want to bring COVID germs into our house from buying a used game on eBay. I do have a container of 70% isopropyl alcohol wipes, and I wonder if wiping down a cartridge with those would work, or if leaving the game outside (inside our garage) for a certain length of time would work. Any suggestions?
