How To Kill Brown Mold in a Toilet

The presence of mold in your home can be hazardous to your health, causing infections, allergic reactions, and respiratory complications.  Unfortunately the warmth and moisture of bathrooms provides the perfect breeding ground for various types of mold.  Although many types of mold are brown, there are common strains that grow in toilets and compromise the air quality in your home.  Before brown mold spreads to other areas of the bathroom, take steps to banish it for good.

  1. If you fail to kill toilet mold completely the first time, it will likely appear again and eventually spread.  A quick cleaning is sure to leave room for new spores to attach to the toilet, so start by setting aside a lengthy period of time for a pre-treatment.  Pour a sizeable amount of bleach into the toilet basin, along the walls, and over the reservoir.  Allow the cleaner to sit for at least 8 hours to loosen the brown mold spores from the porous surface of the toilet.  You should close the lid, but do not flush the toilet.
  2. Keep the bathroom well-ventilated, making sure that children and pets are not exposed to the chemicals.  Since mold spores can float into the air and reattach to other surfaces, it is important to keep the brown mold contained to one area.  If the toilet has no lid, close the bathroom door and, instead, use an open window and a fan to push the fumes out.
  3. Before you are ready to clean the toilet, you may want to buy additional supplies, such as disposable rags or scrubbers, specialized mold cleaner, and rubber gloves.  You should also find a scarf or another type of covering that you can put over your mouth and nose to prevent the inhalation of brown mold spores.
  4. When you are ready, you can begin cleaning the toilet.  Use the store-bought cleaner or a bleach solution to scrub the inside of the toilet bowl, even spots that do not appear to be affected.  When the mold is removed, you can flush the toilet.  You may need to do this more than once to clear away all of the toilet mold.  Use more cleaning solution and scrub the toilet again as needed to be sure that all remaining spores have been killed.  To be thorough, repeat the treatment and cleaning process.
  5. If possible, throw out the rags, gloves, and face covering after you are finished cleaning to prevent the spread of spores.
  6. Avoid the frustrating buildup of brown mold in the future by checking your toilet on a regular basis and find an inexpensive automatic cleaner, such as 2000 Flushes or Clorox Toilet Cleaner.  In the future, try to improve ventilation in the bathroom in order to limit the amount of moisture collecting on the sides of the toilet.
