How to Get Rid of Mold in Your Bathroom

Mold is a type of unavoidable fungus that occurs everywhere. It propagates by spreading lightweight spores through the air and fulfills an indispensable role in our ecosystem by decomposing dead leaves, plants, and trees in nature. No matter if they’re black, green, orange, green, or purple, mold organisms thrive in places with moisture, darkness, and stagnant air.

Humidity present in the basements, laundry rooms, and bathrooms renders the ideal environment for mold growth in homes. If you’re struggling with black mold in the bathroom, then be sure to follow our preventative tactics and cleaning tips. From mold on bathrooms ceilings to walls and in between grouting, we’ll show you how to eradicate this fungus from your home.

Best Black Mold Removal Products for Bathrooms

Black mold removal products like DIY remedies and shelf-bought cleaners can tackle growing spores in your bathroom. As soon as you discover mold, you should remove it, along with the stains it leaves behind. Below are some of the best bathroom ceiling mold removal products that can be applied throughout your home.


Using bleach to kill mold is only effective on hard, impermeable tub and tile surfaces. The chlorine in bleach can’t penetrate porous surfaces like drywall or wood. So, when the porous material absorbs the water component of the bleach, it achieves the opposite of what’s intended and merely provides additional moisture for mold roots to feed on.

This causes a cycle of continuous bleaching, where in some cases, the bleach drains the mold of its color, misleading homeowners to believe they have solved the problem. If you want to bleach mold, you should only do so if it’s absolutely necessary on small surface areas, as it’s not endorsed by the United States Environmental Protection Agency (EPA). If the mold in the bathroom returns, then rather use borax or vinegar.


Also called Sodium Tetraborate, Borax is a natural white mineral and salt powder compound used to kill mold. Mixed with water, this fungicide is effective on all surfaces, including wood and metal. While toxic if ingested, Borax doesn’t emit any harmful chemicals or fumes like other chemical mold killers.

Mold tends to grow in acidic environments with a pH range of 3.5 - 8.0. Borax contains a pH level of 9.13, which completely kills mold and prevents the germination of its spores. You can purchase borax for mold removal for a few dollars at the laundry section in most supermarkets.


The antifungal and antibacterial properties of white vinegar make it an effective black mold killer on nonporous surfaces. However, using vinegar for mold eradication on soft surfaces will likely be ineffective. Applying vinegar to clean mold that’s persistent on floor coverings or other malleable surfaces is almost impossible — it’s safer and more effective to replace the surface.

Both white distilled vinegar with 5% acidity and cleaning vinegar with 6% acidity are equally effective black mold removal products. When using vinegar to kill mold, it’s advisable to avoid natural stone, waxed wood, aluminum, and cast iron as its acidity can damage these surfaces.

Before cleaning mold, it’s important to address the source of moisture that enabled growth to occur, otherwise, it will return again. Any mold in your bathroom traversing an area of 10 square feet or larger should be removed by a specialist, especially if it has penetrated your heating, air conditioning, or ventilation system.

How to Get Rid of Mold on the Bathroom Ceiling?

To successfully get rid of mold in your bathroom, you need to have the right tools, equipment and follow the correct procedures.

Tools and Materials

  • Mold removers like Borax or vinegar
  • Painters tape
  • Plastic garbage bags
  • Plastic sheeting
  • Oil-based primer or shellac
  • Dish soap
  • Rubber gloves
  • Safety goggles
  • Safety mask

Safety Precautions for Removing Mold from Bathroom Walls

Mold contains harmful toxins. For maximum health and safety, we recommend:

  • Wearing old clothes you can throw away or deeply wash afterward
  • Wearing an N-95 respirator, as well as gloves and eye goggles
  • Wrap and tape moldy carpeting in plastic, then double bag it before throwing it away
  • Use an old fan as a ventilator while you’re working. You will need to throw this fan out once you’re done to avoid circulating mold spores
  • Moisten the mold with a sprayer before removing, as this helps control airborne spores
  • Switch off HVAC systems and furnaces, and be sure to cover their ducts before mold removal

Steps on How to Remove Mold from Your Bathroom Ceiling

Seal off the Moldy Area

When killing mold, you want to seal off affected areas to prevent spores from spreading.

  • Keep the bathroom sealed off from the rest of the house
  • Cover doorways with plastic sheets and tape from the wall to the floor
  • Cover all air ducts with plastic and secure them with tape

Removing the Mold from the Ceiling

Depending on the severity of the mold, you may need to set one hour or two aside to complete the job. Here’s how to clean mold from your bathroom ceiling:

  1. Once you have selected your cleaner, close doors leading to the rest of the house.
  2. Put on gloves, goggles, and a face mask. While this may seem excessive, black mold, known as Stachybotrys, can be harmful to your health causing flu-like symptoms like diarrhea, headaches, memory loss, and respiratory damage.
  3. Scrape away paint in the moldy area to expose fungus growing beneath the surface.
  4. Apply your chosen cleaner. Make sure you scrub the cleaner into the surface, regularly rinsing your brush or scourer.
  5. Dry the area thoroughly when finished. Leaving a wet surface will just encourage more mold to grow.
  6. Repaint if necessary

Clean Up After Mold Removal

The cleanup process is just as important to prevent spores from spreading throughout your house. We recommend:

  • Double bag and seal mold materials, like carpets.
  • Bag and seal all rags used for mold removal and throw them away
  • Immediately wash hands and skin
  • Deeply wash clothes using hot water or dispose of them

Tips to Remove Mold from the Bathroom Ceiling

  • Direct a UV lamp at the affected area for 24 hours after you have eliminated the mold. It will kill off any stubborn spores clinging to areas you may have overlooked, as well as remove leftover moisture.
  • Fans can be used to circulate the air and rid the room of any odors from the cleaners or mold.
  • Inspect exterior bathroom walls to ensure there’s no mold growing on the outside wall.
  • Never combine bleach and vinegar because it transforms into Chlorine Gas, which is fatal in high concentrations.

How to Remove Mold From Bathroom Walls?

Mold in bathroom walls can be tricky to remove because homeowners don’t always notice it until it discolors paint. If your home produces a persistent earthy, musty odor, and stains or dampness on the wall, then you may have mold. And if this mold is inside the walls, you will likely have to get professionals to remove it, otherwise, you can follow the same removal process for getting rid of ceiling mold.

In some cases, when mold attaches itself to drywall, it’s best to take down the entire wall or a section of it to prevent spores from multiplying, especially if the wall is damp. If your drywall feels soft, it’s almost impossible to salvage. Then it’s no longer a question of how to clean mold in bathroom walls, but rather when to replace the section of wall.

If you have mold on wallpaper, then you should spray the area and immediately scrub it with a clean cloth or brush to remove the surface layer of mold. Lightly respray the area afterward, wait for ten minutes and then wipe it clean. Let it dry overnight without rinsing to kill lingering mold.

How to Prevent Mold in The Bathroom?

Mold thrives in damp environments, so controlling moisture in the following ways keeps it at bay from your bathroom:

  • Always leave the bathroom door and window open once you’ve finished showering or bathing for at least twenty minutes to allow humidity to diminish. If you have a ventilation fan, then keep it running for the same amount of time.
  • Fix plumbing leaks as soon as possible.
  • Place a moisture-absorbing desiccant in the corner of your bathroom, or run a dehumidifier if you live in a humid climate.
  • Always spread towels out to dry or hang them on the line.
  • Use mold-resistant paint.
  • Clean your bathroom weekly with a strong disinfectant product.


Mold removal is an intricate process, but vital for your health and your home’s longevity. Using the right materials and methods to remove mold in your bathroom is paramount to ensure it doesn’t return and cause further damage. An important step in preventing mold accumulation is to make sure it's thoroughly cleaned on a regular basis. Our experienced team at Euro Maids is happy to help keep your home spic and span.
