Clean hard rust off toilet and tubs?

Question

I have hard rust stains on my toilet and tub, none of the regular cleaning products will take it off. The only thing that will is a little bitty bottle that is expensive. Does anyone know of an old remedy for that that doesn't cost an arm and a leg?

Answer 1

In our toilet we use a bath block......... it's a pumice stone type cleaner about the size of a bar of soap, it scrubs the rust stains right off.  It's only a couple dollars at most hardware type stores.  

Answer 2

Try Brake Cleaner from a car accessory shop. Spray lightly onto a cloth. Regards. UK

Answer 3

Have you tried a product called CLR (Calcium Lime Rust)?
