Hi. I have old toilets in home we bought 3 years ago, probably the original American Standard. The house is 40 years old. There are very stubborn stains and calcium deposits on all 3 toilets. I have tried using CLR, Lime Away, and Bar Keepers Friend with a Dobie Pad to try and get these off, no luck. My last try is pumice stone. Before I go and try this, will the pumice harm the porcelain, or is it safe to use to try and get these stains off? Thanks.
