Every toilet has the perfect conditions for mold growth moisture, nutrients , and a suitable place to grow.

Several reasons can make your toilet become a breeding ground for mold. If your toilet has been left unused for a couple of days, then dont be surprised to see mold growing in it. Likewise, your toilet bowl and tank can grow mold because they are often dark and humid.

Cleaning Inside The Tank

You can easily clean mold that collects above the water line inside the toilet tank and underneath the lid with a chlorine bleach solution. Wear rubber gloves while working with chlorine bleach and avoid inhaling the fumes. After shutting off the toilet supply and flushing, fill the tank about halfway with the bleach solution and scrub the sides of the tank above the water line and the underside of the lid with a kitchen scrubby. After rinsing the sides and the lid with clear water, turn on the water and flush several times to clear the tank of residual bleach.

Vinegar And Baking Soda Method

  • Pour 1 cup of vinegar into the toilet. This is the vinegar I use.
  • Sprinkle baking soda around the inside of the bowl and into the vinegar water in the bowl. Be sure to get some up under the rim.
  • Sit back and watch the volcano of fizz erupt!
  • Let the vinegar/baking soda sit in the toilet for an hour or more with the lid closed.
  • After an hour, scrub the mold with a toilet brush or similar non-abrasive material. You want to move the vinegar water around the bowl and brush really well under the rim.
  • Let the toilet sit again for about 15 minutes with the lid closed.
  • Flush the toilet.
  • Still see some mold? Scrub any remaining mold stains with a toilet brush or similar non-abrasive material.
  • Still see some mold? Repeat this entire process a second time.
  • After you are mold free, let the toilet sit with the lid closed for 3-5 hours before using it again.

    Mold Vs Manganese Black Spots In A Toilet Bowl

    Mold spores are always present in our homes. They however thrive in dark, warm and damp surfaces like the toilet bowl or even inside the toilet tank. Apart from black, mold can also be green, grey, orange, purple, pink or even even red.

    To prevent mold from growing in your toilet bowl or other fixtures, clean them regularly using baking soda and vinegar. The vinegar penetrates through surfaces thereby killing their roots.

    Since molds need oxygen to grow, they will be found above the toilet bowls waterline where there is an ample supply of air. Constant flushing of the toilet supplies them with the moisture they need to thrive.

    If you live in an area with hard water, it will be manifested in your fixtures like toilets, tubs and sinks. The minerals found in hard water in large concentrations are iron, manganese and calcium.

    Iron forms reddish brown spots in a toilet bowl and in most causes a red a ring around the waterline called a toilet ring. Calcium forms a whitish or creamy accumulation in the bowl.

    The best way to get rid of hard water stains in toilets and other fixtures is by installing a water softener. A water soften removes the hard water minerals before the water enters your house, which also prevents clogging of pipes and appliances.

    Another option for removing manganese from water before it stains your toilets and other fixtures is by installing an iron filter. This is because manganese and iron are almost chemically identical hence the same removal process.

    Health Risk Of Black Mold

    Mold is gross to look at but what is the real risk? It turns out that mildew and mold growth in the bathroom does not pose a serious health crisis unless the mold spores begin to spreadthrough the rest of the house.

    Some types of mold become a danger when allowed to spread on surfaces with cellulose, which is found in wood and wood-derived materials such as paper and fiberboard.

    If the mold penetrates the walls, floorboards, and rafters, the toxic mold may develop.

    In bathrooms, the mold is more likely to cause minor respiratory issues in some individuals. Potential symptoms include:

    • Itchy eyes
    • Rashes
    • Skin irritation

    During a severe reaction, you may also find it difficult to take deep breaths. If you detect these signs, remove mold and consider having your property inspected for the spread of moldthrough other areas.

    While mold is rarely a danger, remove it before it has the chance to spread. It can easily travel through air ducts and settle in rooms throughout the house.

    Mold Under The Toilet Rim


    The shade and humidity in the underside of the toilet bowl are an ideal place for mold fungus to thrive. Even when using a disinfectant, you may still find it difficult to clean the brown or black discolorations under the rim. It could be that the tank is feeding mineral deposits or organisms into the bowl.

    What you will need: Undiluted white vinegar in a spray bottle, some bleach and a soft brush.

    1: Spray white vinegar onto the affected areas and scrub with a brush until all the fungi comes off.

    2: Wipe all areas of the seat down on top, sides and underneath with bleach on an old cloth. The bleach will disinfect and kill any remaining spores.

    3: Wipe the bleach from the seat with warm soapy water and dry it off completely.

    If Its Growing In The Toilet Tank

    Mold which is growing in the toilet water tank may be due to the following causes

    • Infrequent flushing if the toilet in question is not used very often this can lead to mold or mildew. The water turns stagnant and mold spores enter and feed on nutrients and algae which tend to be present in the water supply. Also, the stagnant water will gradually lose the effectiveness of the chlorine which helps prevent mold formation and the temperature may warm to room temperature, making it even more attractive for mold to make a home.
    • Contaminated water supply see above.
    • Infrequent cleaning most people do not think to clean here often, if ever, and so there may be mineral deposits on the sides which can gather and feed any mold spores that manage to get in. It is also dark which mold loves.

    The Problem With Mold

    While mold doesn’t have the same effect on everyone, the Institute of Medicine found in 2004 that there is enough evidence to link mold with upper respiratory ailments and coughs, reports the Centers for Disease Control and Prevention. Moreover, it can induce symptoms of asthma in people with that disease.

    Researchers have suggested links with other adverse health effects, such as memory loss and lethargy, but no causal connection has been proven. In short, if you are sensitive to it, mold can cause considerable respiratory discomfort. Even if you aren’t particularly sensitive, mold creates an environment in which it is easier for you to contract lung infections.

    How To Remove Black Mold From Toilet Tank

    Have you opened your toilet tank and discovered that black mold is growing inside? If so, keep reading because Im going to show you how to remove black mold from your toilet tank easily and effectively.

    When we first moved to Japan, we did a lot of research on what we needed to know about the country.

    We thought we had it pretty well covered, but one thing we hadnt accounted for was mold growth inside our house.

    Japan can get very humid in the summer. The combination of high humidity and darkness is the perfect breeding ground for black mold which is why I was shocked and disgusted to open my toilet tank after six months of living in Japan and discover that it was covered in black mold.

    Fortunately, a small amount of black mold like this is easy to remove and doesnt generally require you to call in a professional mold removal company.

    What Causes Mold In Toilet

    Mold is a type of fungus that can grow on many kinds of surfaces, and most often appears when the surface is allowed to become damp. Any room of the house can develop a mold problem as long as there has been some contact with moisture, whether that moisture comes from the outside, from plumbing problems, or through high levels of air humidity. Bathrooms are particularly susceptible to the growth of mold because there are so many ways and places for moisture to collect.

    Toilets are by definition, moist environments: both the bowl and tank are partly full of water at all times except during the act of flushing. Theyre also dark areas, especially when the lid is closed, and are naturally at room temperature. These conditions are perfect for mold to thrive.

    Toilets that are used infrequently and not flushed often are more likely to develop a mold problem than those that are flushed many times a day. All toilets need to be cleaned regularly to prevent mold spores from growing and expanding into a larger problem.
