Now that I got the pin working properly and I am replacing bumper skirts, I thought it is a good time to clean the playfield. So, in the pic you can see dirt streaks or dirt after using/trying Naptha, alcohol, ME, Novus #2. I just can get this any cleaner. It's a lot better now than when I started, but is this the best I would get or am I missing another cleaning method.
Thanks
Steve
