The motive: Traditional formulas work for a bit, but this solution’s polymers coat the surface for six months, keeping it slick so nothing sticks.
The method: Clean the toilet to remove existing stains, then back the water out. This is easy: Shut off the water valve by turning it all the way to the right; flush the toilet, holding down the handle until most of the water flows from the tank; and pour a bucket of water into the bowl. Dry the interior with a cotton cloth, and use a separate cloth to apply the protectant. (Try 3M Performance Finish Synthetic Wax; $20, amazon.com.) Make sure to open a window for ventilation. Let sit for 10 minutes, then replenish the water by turning the valve left to open. For upkeep, every three months pour ½ cup distilled white vinegar into the bowl to prevent water rings from forming.
