Toilet bowls are constantly filled with standing water. When you have a hard water supply, this standing water contains minerals which settle onto the surface of the toilet bowl. These typically dry a dirty brown shade, quickly making your toilet appear unclean. To clean the hard water stains, forget the expensive toilet bowl cleaning products and make your own homemade cleaning solution.
Pour 1 cup of baking soda into the toilet bowl with 1 cup white vinegar. Place the lid down on the toilet bowl
Let the solution sit for 10 minutes. The combination of these ingredients will loosen the hard water stains.
Scrub the toilet bowl with a toilet brush until all stains are removed.
Flush the toilet to rinse the bowl clean.
