Black Mold in Bathroom   What Should I Do About It

Any health professional would tell you that having black mold in your bathroom even for a short period is potentially dangerous. Research has shown that prolonged exposure to toxic varieties of black mold in living environments can trigger or exacerbate lung-related health conditions such as asthma. It may also affect household pets.

Here are some of the possible dangers of being exposed to toxic black mold for long periods in your bathroom:

  • Mold poisoning- mycotoxicosis
  • Allergies and asthma
  • Bronchitis
  • Respiratory infections-
  • Chronic coughing and sneezing
  • Lung cancers, etc.

There is evidence that exposure to toxic black mold(Stachybotrys chartarum) can cause immediate reactions in humans. You will most likely experience symptoms such as sneezing, headaches, and skin rashes if you are exposed. Children, people with existing lung conditions, and older people are more likely to have worse reactions.

The best cause of action if you have been exposed to black mold is to seek advice from your doctor. At the same time, you should also see to it that the mold has been removed.

Is Black Bathroom Mold Dangerous cleaning

Removing black mold and preventing further growth requires careful planning and proper cleaning. Generally, it is recommended that you have a professional do an inspection and remove it safely. They could also do other tests to see if the mold had spread to other areas of your home such as attics and basements.

That said, you can still remove small patches of black mold by following these steps:


You need the following items while removing the mold:

  • Gloves-
  • Face mask or respirator.
  • Goggles
  • Disposable coveralls
  • Garbage bag
  • Mold removal reagents/chemicals

Step 1- Identifying and Isolating Affected Areas

The first thing you should do is to identify the affected surfaces in your bathroom and shower. Sometimes small patches in exposed surfaces such as shower curtains could be a sign of a bigger problem. Black mold tends to thrive in dark, damp, and hidden areas.

Inspect the following areas and note areas that have the mold to be cleaned as a priority:

  • Shower screen or shower curtain
  • Behind sinks and toilet seats
  • Shower surfaces
  • Bathroom doors
  • Window surfaces
  • Hidden surfaces
  • Inside the shower ceiling
  • The external wall directly behind the shower.
  • Shower fixtures such as lights

You should ideally have the entire washroom or shower thoroughly inspected and cleaned to ensure that all the mold has been removed. Use a flashlight or infrared light to identify mold particles in dark or hidden areas.

Step 2: Preparation

After identifying the areas affected by the mold, the next step is to prepare for cleaning up.

  1. Start by sealing off the bathroom so that airborne mold particles do not float to other areas such as corridors. You can use duct tape or heavy plastic or any material of your choice to ensure that there is an airtight seal on doorways, ventilation, and windows.
  2. Removable items such as shower curtains, carpets, and towels should be bagged and cleaned separately using hot water and normal cleaning products or replaced.
  3. Keep the external windows or ventilation open and if possible, have an exhaust fan or vacuum to suck off all the mold away from the bathroom as you clean.
  4. Wear your protective equipment (mask, gloves, and goggles) before you start removing the mold so that you do not inhale disturbed mold particles. Black mold spores tend to break off and become airborne at the slightest touch.
  5. Prepare your mold cleaning chemicals and reagents. You can purchase off-the-shelf mold removal products and mold bombs if you have a mild mold problem.

Here are some of the reagents and chemicals you can use to clean off mold from your bathroom:

  • Concentrated bleach
  • Dissolved baking soda mixed with white vinegar. Mixing baking soda with white vinegar and water may be more effective in some cases.
  • Borax
  • Ammonia- effective at removing mold from tiles and glass in your bathroom. Mix it with water and spray it with a spray bottle.
  • Laundry detergents
  • Hydrogen peroxide
  • Mold removal compounds- there are a variety of special-purpose mold removal compounds you can purchase. Make sure the one you purchase is rated for black mold removal.

Step 3 Removing the Mold

After mixing your cleaning reagents, it is now time to start removing the black mold from your bathroom. Depending on the surface you will be cleaning, you will need to use the appropriate cleaning tool to remove the mold. For instance, use a scrubbing brush and sponge to remove mold from tiles and wall surfaces.

  1. Start by applying the cleaning chemical or compound of your choice on the surface with mold. You can also use a spray bottle or spray can for vertical surfaces and hard-to-reach areas.
  2. Scrub off the mold carefully using a brush making sure you cover every inch.
  3. Rinse off the area with a rough cloth and hot water to make sure all mold spores have been eliminated.
  4. For some chemicals such as borax and vinegar, you may need to saturate the area and wait until the mold has been killed by the chemical before you brush and rinse the area.
  5. Ensure that the entire bathroom or shower has been cleaned off and that all the identified mold has been eliminated.
  6. Dispose of the cleaned mold particles in an airtight garbage bag clearly labeled that it contains toxic substances. Alternatively, you can discard the mold by flushing it down the toilet.
  7. Clean your PPEs and make sure all mold particles have been removed.
  8. Some items such as shower curtains and carpets affected by black mold are better replaced with new items after the cleanup as it can be difficult to eliminate tiny black mold particles from porous materials such as cotton.

Step 4: Post-Removal Inspection

It’s not enough to remove black mold and start using the bathroom immediately. Black mold tends to spread quite quickly meaning any remnants could be a problem in the future. It is best to do a thorough inspection after the cleanup and test surfaces for traces of black mold particles. Professional inspectors use a series of tests to check that mold has been properly removed.

As part of the post-inspection, you should check that the root causes of black mold are identified and fixed. For instance, check that there are no leaking pipes and that there is proper ventilation. This will prevent further mold formation in your bathroom and other areas.
