any idea what my vintage sink find is made of and how to restore?
Hello! I just purchased a vintage sink that will be perfect for our kitchen remodel. I am not sure what material it is made of, however. It is some kind of metal underneath, but is white on top. Not cast iron, as it is fairly light to lift. Not acrylic on top. I'm wondering how to clean it and if anyone has tips on restoring it? Just a bit of rust on the white surface and on the underside of the sink. A couple of chips that I may just leave alone if it is too costly to repair. Thoughts?
