    Try Barkeepers Friend. Helped me remove stubborn rust stain on tub when nothing else worked. Took a couple tries but finally got the job done.

    Unless you want to keep removing the stain you should figure out what is corroding in your water supply system that is producing this stain. I would start with the water heater. When was the last time that it was drained?

    All the household pads and products may help the surface, but if the stain is in the porcelain, in the end, you will end up using muratic acid. But I agree, you should get to the source and see if it cannot be simply fix so it is not a constant maintenance issue.

    If you can get it in NZ try a "Pumie" brand scouring stick. We get them here in California at our 99 cent Only store, but I've seen them online too at somewhat inflated prices.

    You can have the mineral content checked. You may have to put some type of particle filter on your water lines. You didn't mention if you have the stains in any other area. If it is just in the bath, you could check the connectors on those pipes. You may have to replace them. We are on a well and have iron deposits, so we are constantly fighting them...

    This might be a sign that it is time to have your water heater flushed and the dip tube and anode rod replaced.
