I have been using rubbing alcohol and q-tips to clean the contacts on my game cartridges for a while now. I just wanted to make sure that this method is safe and will not harm the cartridges over time?
The way that I clean a disc is to wipe it with a microfiber cloth slightly dampened with water. Is this a good/safe way to clean discs? I used to use one of those rotary cleaners where you spray a solution on the disc and then turn the crank on the rotary unit which rubs the disc with a pad. Is that a safe method?
