I have a mirror that I think is framed in tin or aluminum that I got in San Antonio, TXWhile being stored it rustedWill anything take that off?
Try toothpaste, preferably not gel.
It would be tin, not aluminum since aluminum doesn't rustNavel Jelly will damage the paint on the back of the mirror if any leaks behind the frame so I suggest you use graduating steel wool to burnish away the rustYour final finish could be made shiney with a polishing rouge if you want or leave it matte finished once you complete the removalI have 35 years experience in antique restoration.
