Being new to country living I didn't know how to get hard water deposits off of toilet bowl with out damage to surface. Nothing worked and it just got worse. Finally put in softner but rings still there. Had a real hard water expert (retired aircraft carrier captain) visiting and he told me answer. PUMICE - works great. Not found in any stores I frequent, finally found pumice sticks on ebay. Bought two which turns out to a lifetime plus supply. Cheep and effective!
