Acetone nail polish for cleaning crud
I know, I know it sounds risky but I was desperate! I was working on the grungiest, most disgusting 401 and after much soaking, etc. with the usual kerosene, Krud Kutter, etc., in desperation I tried nail polish remover containing acetone. I could not believe how the gunk and grime wiped off with just a light touch! I was very cautious at first thinking I might damage the paint but the only thing I removed was crud! I would never try this on a black shellac finish but cheap dollar store remover worked like a charm for me on my "newer" 401.
