Noticed black spots or mold in your toilet? Mold in toilets is a common problem that many homeowners face, especially in areas with high humidity or poor ventilation. Left untreated, mold can spread, damage surfaces, and pose health risks to your household. Fortunately, with the right remediation tips and prevention strategies, you can get rid of toilet mold and keep it from coming back. In this guide, we’ll cover how to remove mold from your toilet safely, why it forms, and what you can do to stop it from growing again. If mold persists or spreads to other areas, consider calling Citywide Mold Mitigation for professional remediation services.

Why Does Mold Grow in Toilets?

Toilets provide the perfect environment for mold growth due to the constant presence of water and moisture. Mold spores thrive in damp, dark areas, and toilets — especially those not used often — can become a breeding ground for mold. Additionally, mineral deposits in the water or organic matter can contribute to the growth of mold, particularly around the bowl and under the rim.

Common reasons for mold growth in toilets include:

  • Standing water: Mold thrives in stagnant water, making toilets with poor flushing mechanisms or those left unused for long periods susceptible to mold buildup.
  • High humidity: Bathrooms with high humidity levels are more likely to develop mold, especially in areas that are not properly ventilated.
  • Lack of cleaning: Mold can form in toilets if they are not regularly cleaned, particularly in hidden areas like under the rim where mold spores can accumulate.

How to Remove Mold from Your Toilet: Step-by-Step Guide

Getting rid of mold in your toilet may seem daunting, but with the right cleaning methods, it can be done safely and effectively. Follow these steps to eliminate mold and restore your toilet to a clean, mold-free state:

Step How to Do It
1. Wear Protective Gear Mold can cause allergic reactions and respiratory issues, so it’s important to wear protective gloves and a mask while cleaning. This will protect you from mold spores that may become airborne during the cleaning process.
2. Use White Vinegar White vinegar is a natural mold killer and an effective cleaning solution for toilets. Pour one cup of white vinegar into the toilet bowl, making sure to cover the moldy areas. Let it sit for 30 minutes to break down the mold before scrubbing.
3. Scrub with a Toilet Brush After letting the vinegar sit, use a toilet brush to scrub the bowl thoroughly. Pay extra attention to the areas under the rim, as mold often grows in these hidden spots. For stubborn stains, use a pumice stone to gently scrub the mold without damaging the porcelain.
4. Flush and Repeat After scrubbing, flush the toilet to remove the mold and vinegar. If any mold remains, repeat the process until the toilet is clean and free of mold stains. For extra cleaning power, you can add baking soda to the bowl along with the vinegar.
5. Clean the Tank Mold can also grow in the toilet tank, leading to recurring mold issues in the bowl. Pour a cup of white vinegar into the tank, let it sit for 30 minutes, and then scrub the inside of the tank with a brush. Flush the toilet to rinse out the tank.
6. Disinfect with Bleach If the mold is particularly stubborn, you can use bleach to disinfect the toilet. Pour half a cup of bleach into the toilet bowl and scrub thoroughly. Be sure to use bleach sparingly, as it can be harsh on your plumbing system and the environment. For more eco-friendly alternatives, see Good Housekeeping’s cleaning guide.

If the mold in your toilet persists or if you notice mold spreading to other areas of your bathroom, it may be time to call in the professionals like Citywide Mold Mitigation for a thorough mold inspection and remediation.

Natural Solutions for Removing Mold from Toilets

If you prefer natural cleaning solutions, there are several eco-friendly options that can effectively remove mold from your toilet without the need for harsh chemicals. Here are a few natural alternatives:

1. White Vinegar and Baking Soda

As mentioned earlier, white vinegar is an excellent natural mold killer. For added cleaning power, mix white vinegar with baking soda to create a fizzy reaction that helps break down mold and stains. Sprinkle baking soda into the toilet bowl and pour vinegar over it. Let the mixture sit for a few minutes before scrubbing with a toilet brush.

2. Tea Tree Oil

Tea tree oil is known for its antifungal properties, making it a great natural solution for removing mold. Add 10-15 drops of tea tree oil to a spray bottle filled with water and spray it onto the moldy areas of the toilet. Let it sit for 10-15 minutes before scrubbing with a brush.

3. Lemon Juice

Lemon juice is a natural disinfectant and can help remove mold stains while leaving your bathroom smelling fresh. Apply lemon juice directly to the moldy areas and scrub with a brush. This method works particularly well for lighter mold stains and regular maintenance.

How to Prevent Mold from Growing in Your Toilet

Once you’ve removed mold from your toilet, it’s important to take steps to prevent it from returning. Here are some effective ways to keep mold out of your bathroom:

1. Flush Toilets Regularly

Mold often forms in toilets that aren’t used or flushed regularly, as stagnant water provides the perfect environment for mold growth. Be sure to flush toilets at least once a day, especially in bathrooms that don’t see regular use.

2. Lower Bathroom Humidity

High humidity is one of the biggest factors contributing to mold growth in bathrooms. Use an exhaust fan or open windows after showers to improve ventilation and reduce humidity levels. You can also place a dehumidifier in the bathroom to keep moisture levels under control. Learn more about controlling bathroom humidity at HGTV’s dehumidifier tips.

3. Clean Toilets Weekly

Regular cleaning is key to preventing mold from growing in your toilet. Clean the toilet bowl and under the rim at least once a week using a disinfectant or a natural cleaner like vinegar. Don’t forget to clean the toilet tank as well, as mold can grow inside the tank and spread to the bowl.

4. Use Vinegar as a Preventative Solution

To keep mold at bay, pour a cup of white vinegar into your toilet bowl once a week and let it sit for 30 minutes before scrubbing and flushing. This simple routine will help prevent mold from forming and keep your toilet smelling fresh.
