Put tart pan in dishwasher- aarrgh!

[ochound]

don't ask me why, but I did- now it's all rusty/cruddy. It has the removable bottom, both parts were affected. Imagine they were pretty cheap (part of a set of 3 sizes)- just toss it? Any way to get the rust off? I tried an SOS pad, but no luck-

They are probably tinned steel tart pan and the tin just get wash off and needless to say the steel rust. I think you can try Bar keeper's friend if the rust is not too deep. Bar keeper's friend has a somewhat rust removal ability to it. You can always use more specific rust removal solutions.
