Remembering the old way to clean a NES cartridge versus the modern fix
Back in the day, when my NES would flash that gray screen, the fix was to blow into the cartridge. We all did it, even though we knew deep down it was bad. The moisture from your breath could speed up corrosion on those gold pins. A few years ago, my old console from 1987 started acting up again, and I decided to try the proper method I'd read about. I opened a cartridge, got some 91% isopropyl alcohol and a cotton swab, and gently cleaned the contacts. The difference was night and day. The game booted up first try, no wiggling, no blowing. It was a simple, dry clean versus a wet, damaging one. Has anyone else made the switch and noticed their games work more reliably now?
