You have a wonderful product in Super Iron Out, I don't know what your product is made of, but it instantly dissolved the rust stains in both of our toilet bowls caused from a continuous water leak. One rust stain was quite bad, as we had gone away on vacation for 2.5 weeks!!! It worked much better than CLR as you don't have to do any scrubbing to remove the stain, just pour the powder and on, it seems to magically cling to the side of the toilet bowl and erase the stain. So glad I found out about Super Iron Out, which I found by doing an internet search on how to remove rust stains from toilet bowls. I think I saw it on eHow.
