I am having a hard time with well water rings in some toilets. Is there anything out there, simple, to use. I've tried a can of coke, which gets out many other stains, but it didn't work on the well water.

If you find that your toilet is stained even after you’ve cleaned it, then you might need to enlist a stronger cleaning agent. If you decide to get rough, be sure to flush the toilet and turn off the water, getting out as much water from the bowl as possible. Having less water in the bowl means less dilution of the cleaning agents.

When you use these cleaners make sure to use an all-plastic scrub brush. Don’t use those toilet brushes with metal wires and plastic bristles poking out of them. The metal can scratch and permanently damage a toilet. Hope that helps! Evette
