Try Comet

You need something containing oxalic acid. "Bartenders Friend" or
"Stainless Steel Cleaner" work fairly well. Dump a bucket of water down
the toilet to empty the bowl so it will dry before you work on it.
Another easy to use cleaner is plain old dishwasher detergent. Keep it
clean with a couple of denture cleaners once in a while. Do not use
cleanser or pumice.
