removing rust from a vintage painted cast iron doorstop
Hi Margo. Check out your local auto-parts store and look for a rust remover/polish made specifically for chrome parts. Because chrome is a really thin plating over metal, it requires a very gentle polish, which should make it safe to use on a painted surface as well (if the correct type of paint was used on the doorstop). Of course, you should test an inconspicuous area first to make sure it doesn't damage the paint. Best of luck!
