Today I made a major break through with the high iron, hard water toilet bowl situation. I turned off the water to the toilet, flushed it until it was almost empty, then poured a whole gallon of distilled (white) vinegar into the toilet and left for my 3 hour water color painting class. When I got back I turned on the water, rubbed the bowl briefly with a toilet brush, and voila! My toilet looks brand new! This sure beats scrubbing it with a pumice stone.
