I also use the 99% rubbing alcohol followed by ProGold contact cleanner. A friend uses model railroad track cleanning solution on his copper audio contacts. Don't forget to clean the the power cord contacts. Skip the ones in the electical out let unless you are qualified to play with the AC. Don't use the 99% pure rubbing alcohol on skin, it dries it out. Don't crush red chile pods with your fingers, run your fingers through your hair, and then take a shower. It's REAL PINFULL!
