Black Rings Inside a Toilet Bowl

Black rings around the toilet not only look disgusting, but they may be a buildup of toxic materials that smell bad and can potentially put your health at risk. A constant shift between wet and dry conditions inside a toilet bowl makes the perfect breeding grounds for dirt and mold. Knowing what type of stain you are trying to remove will help determine the proper cleaning solution.

What Creates Black Rings Inside a Toilet Bowl?
Hard Water Deposits: Anytime a surface that comes in contact with your home’s water supply on a regular basis such as faucets, shower heads, and toilet bowls, it becomes susceptible to an accumulation of residue. Water flows from the toilet tank and into the bowl through series of small holes or ports located under the rim. Over a period of time, hard water deposits will begin building not only in the ports but also around the port openings and the rim of the toilet. When this happens, residue provides a non-slick coating for waste and other grime to collect where it will not wash down the drain after each flush.

Mold and Mildew: Your toilet is its own enemy when it comes fighting off mold and mildew. Both fungi require a moist environment to stay alive. Because water deposits build-up under a toilet’s rim, it can take only 24-48 hours for colonies to start breeding. As it grows, you will see what looks like black debris or rings inside the bowl. This can cause respiratory problems for people as the mold and mildew release tiny spores into the air.

Sewer Organisms: These are living things, not visible to the naked eye that feed off waste in sewer systems and drain pipes. During hot and humid weather, they may pass through a toilet’s trap and make their way into the bowl. Once this happens, they will live under the rim and release a smell similar to a sewer after each flush.

Get Rid of those Rings!
Commercial cleaners and bowl scrubbers alone will not entirely get rid of the black ring in your toilet. For hard water deposits, add ½ cup of vinegar into bowl. Let it sit for a few minutes before adding ½ cup of baking soda. You will notice the ingredients in the water will begin to fizz. When this happens, oxygen is being released and starts to breakdown the stain. Use brush to remove leftover residue. To clean, sanitize, and eliminate mold/mildew stains or sewer organisms use bleach. Flush toilet before cleaning. Apply 6 oz. under and around rim to coat the inside of bowl. Scrub entire surface and allow solution to sit for 5 minutes for sanitizing; then flush. Do not allow anyone or pets to access the toilet during this time. Because your safety is our top priority, please use proper safety measures when addressing these stains! Use rubber gloves and safety glasses when cleaning.

NOTE: Never mix cleaning solutions! When certain chemicals are combined, they will release a toxic gas that is extremely dangerous or fatal when inhaled.
