From cascading down your toilet bowl to collecting around the top of the bowl, black or grey water marks only increase in time if not removed on a regular basis. The marks are due to build-ups of manganese and other minerals in your well, city or town's water supply. Don't use a chemical or solution that will damage your toilet's finish or just mask the marks. Instead, use a combination of cleaning tools and natural solutions.

Things you need
- Cream of tartar
- Hydrogen peroxide
- Latex gloves
- Old spoon
- Soft cloth or rag
- Warm water
- Disinfectant/detergent cleaner
- Pumice stone (optional)
Mix 1 cup of cream of tartar and 1 cup of hydrogen peroxide in a bucket. Wear latex gloves to keep your hands clean and dry. Use an old spoon to stir the mixture into a paste.
Apply the paste to the black or grey marks, using a soft cloth or rag. Let the paste stand on the marks until the paste dries.
Wet the cloth or rag with warm water. Scrub the paste thoroughly into the marks, using the wet cloth or rag.
Fill the bucket with warm water and 1/2 cup of disinfectant or detergent cleaner. Pour the solution slowly into the toilet, then scrub the entire toilet with the cloth or rag.
Flush the toilet and repeat steps if one or more black or grey water marks are present.
Tips and warnings
- If your toilet is made out of vitreous china or is not coloured, plastic or enamel, you can use a pumice stone to remove the black or grey marks. Wet the pumice stone first, then scrub the mark until it is gone. Complete steps 4 and 5 to finish cleaning your toilet.
