How to Get Black or Gray Water Marks Out of the Toilet
Water marks are unattractive but removable from your bathroom's toilet. (Jupiterimages/Photos.com/Getty Images)

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.

Instructions

  1. 1

    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.

  2. 2

    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.

  3. 3

    Wet the cloth or rag with warm water. Scrub the paste thoroughly into the marks, using the wet cloth or rag.

  4. 4

    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.

  5. 5

    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.
