Pour a quarter cup of bleach directly into the water inside the toilet bowl. Hold the measuring cup close to the water when pouring to prevent any bleach from splashing. Maintain a safe distance from the interior of the bowl to prevent the inhalation of bleach fumes.
Distribute the bleach and water solution throughout the bowl using a toilet brush. Include the underside of the rim and the entrance to the drain hole.
Allow the bleach to remain in the water for 10 minutes.
Flush the toilet. Scrub the inside of the bowl thoroughly with the toilet bowl brush
Combine 1 ounce of bleach with 7 ounces of water in a liquid measuring cup.
Set the bleach solution aside long enough to remove the lid covering your toilet tank. Set the lid out of the way.
Locate the overflow pipe inside your tank. The pipe stands vertically and contains an opening at the top.
Pour the bleach solution into the opening at the top of the overflow pipe.
Allow the bleach solution to work for two minutes before flushing the toilet.
