GETTING READY
First, do all the cleaning inside the machine--the built up lint, thread bits, etc. Clean up dried oil on the works.
Second, remove the plated parts: the end cap, balance wheel, slide plate and needle plate, and so on. These don't have a shellac finish, so getting shellac on them will not help. Take off the bobbin winder and belt cover, to get them out of the way.
Then go over the machine lightly with a rag dampened (not soaked) with the naptha. This will remove dust and dirt. Some damaged spots in the finish may turn white in this step.
Do any paint touchup needed with a Testors paint pen, as mentioned before. Let dry.
Things to avoid: GoJo or other hand cleaners, kerosene, paint thinner, rubbing alcohol--these can damage the decals.
