I know everyone says to stay away from contact cleaners especially those that are flammable . I found something called LPS Electro Contact Cleaner. It actually has a picture of what looks like the same type of switches in a pinball machine. I was wondering if anyone here had tried it and if so, how did it work for you? I was thinking of trying it on an EM pin that is really gunked up. I asked a respected expert on pins and he didn’t have any experience with this particular product.
Thanks for the help!
