I thought about trying the acetone when I read about that. I've gotten sidetracked with the foil thing in the front, and the oil gunk under the stitch length knob covering the decal. I've been working on it for two hours today. It looks a lot better, but I'm not finished with it yet. When I get back to that area I'm going to try that acetone. I see where part of the decal on the front has a perfect line like someone shielded that part from spray.
I'm also working on a completely rusted up White Rotary. Parts are soaking in Evaporust. I can't get some screws off yet, but Mr. Wrench is doing his thing.
Thanks for the reply! How's your machine coming along?
