Starla, I don't know of any "stain" for metal although there might be one out there. However, there are many products available that will make your metal cabinets look like anything from wood to marble. Removing the paint is as simple as using a paint stripper or sanding. I'd suggest that you visit a paint store, not Wally World, but a real paint store and tell them what you have and see what they've got. They'll have literature on almost anything that they sell and will be happy to give you instructions.
