Prevent Toilet Bowl Rings
Pour a cup of white vinegar into the toilet once a month to prevent hard water rings from forming. Let that set overnight then scrub with baking soda the next morning. Note: Vinegar will not prevent the rings caused by the iron in well water nor is it a deterrent against rust.
After cleaning the toilet, back the water out by turning off the valve at the back and flush. Dry the bowl then apply Advantage to the bowl. The polymers in Advantage that do such a great job shining and protecting your car leave a slick coating on the surface. When the surface is slick - nothing sticks!
Clean your toilet weekly by spraying diluted CleanEz into the toilet and sprinkle in a bit of baking soda. Scrub with a toilet bowl brush that does not have metal parts. Those scratch the bowl.
