So Im finishing up getting the 72 Sears Coldspot back together after repaint. The handles have some spots of crusty dried on gunk. If they were solid chrome or plastic Id try soaking in soapy water. The handles are chromed pot metal with a wood grain insert in the face. The insert is metal but Im not sure if the wood grain is painted or a decal. If I had to guess Id say not a decal because there is no wear showing which I think a decal would show after 45 years. It looks as though the inserts snap into place as it's possible to push the edge away from the handle base. I got a small screwdriver under the edge of the insert and lightly pried thinking it might pop off but it didn't seem like it wanted to come off at the top or bottom which is where it seems to be the most secure. One of the handles has a spot of gunk directly on the wood grain. Soaking would probably work to loosen the dirt but I'm hesitant to take a chance on ruining the wood grain by doing that. Any thoughts?
