Hi Andy4707 I have always used oxalic acid to remove iron rust from bottles. Will also work on porcelain. Same as I use for removing iron rust from mineral specimens. It is also used to bleach wooden decks on sailboats. No way near as corrosive as Muriatic or hydrocloric acid. Can be neutralized with baking soda. Use eye protection and don't heat and breath in fumes. Comes as powder,dissolve in warm water in plastic or glass container. Recommend rubber gloves to take items out of acid solution then rinse with water. I have taken stuff out with bare hands but it stings if you have any open cuts, about like vinegar. My suggestion.
