Hey guys, I've got a small set of about 500 CPC chips that are in dire need of a good cleaning. I've never cleaned or oiled chips before and quite frankly have no idea what I'm doing. Should I invest in a cheap ultrasonic (if so any recommendations)? If not what's the quickest and easiest ways to get my nasty looking 1s back to new?? Thanks again for all the help! I'm planning to start collecting finally. So here goes nothing!!
