How to Clean Mold from Bathroom Ceiling

When faced with mold spreading across your bathroom ceiling, there are two crucial steps to take. Firstly, it is essential to identify the source of the mold. If there is a leak from above, it is necessary to fix it before attempting to clean the mold from the bathroom ceiling.

In cases where moisture in the bathroom is the cause of the mold growth, installing an exhaust fan or running a dehumidifier can help to reduce heat and dampness in the room.

Once the source of the mold has been eliminated, the next step is to clean the mold from the bathroom ceiling. Begin by spraying the affected area with a solution of vinegar. If the ceiling is covered with a finish that can be scrubbed, apply the vinegar directly on the ceiling and wipe with a clean cloth.

However, if the finish does not allow for scrubbing, it may be necessary to remove and replace the affected ceiling area. Removing mold from a textured ceiling is best left to mold removal specialists who possess the proper ventilation masks and protective clothing to handle the task safely.

How to Clean Mold off Bathroom Walls

Much like cleaning mold from bathroom ceilings, removing mold from walls can be accomplished using soap and water or vinegar in a spray bottle.

If your walls have a scrubbable paint finish, applying vinegar directly onto the mold and scrubbing it away is an option. After cleaning, allow the area to dry completely, and then cover it with a paint that contains a stain-blocking additive.

However, if you have tiled bathroom walls, follow the cleaning instructions that we have provided in the following section.

In cases where the mold has infiltrated the drywall or has spread across the entire wall, it can be challenging to remove it on your own. It is recommended that you hire a professional to handle the mold removal process.

Attempting to remove that much mold by yourself can pose a health hazard and may cause the mold to spread to other areas of your home.

How to Clean Mold from Bathroom Tiles

One effective way to clean mold from bathroom tiles is by using either vinegar or a borax solution. For smaller areas, mix 2 tablespoons of borax into 2 cups of warm water and transfer the solution into a spray bottle. Spray the solution on the affected tiles and leave it for a few minutes.

As mentioned earlier, you can also create a larger cleaning solution by mixing 1 cup of borax with 1 gallon of warm water. Use a mop or sponge to scrub the mold away from the tiles. Whether you use vinegar or borax, there is no need to rinse the solution.

However, it is crucial to dry the floor completely to prevent moisture from encouraging the mold to return.

To remove mold from bathroom tile grout, you can also use the same borax or vinegar solution. Apply the solution directly to the grout lines and allow it to sit for a while. Use a small-bristled brush, such as a toothbrush, to scrub the mold away from the grout.

For stubborn stains, you can mix two parts of baking soda with one part vinegar to create a paste. Apply the paste to the grout and leave it for a few minutes before scrubbing away the mold. Alternatively, you can use a commercial grout cleaner if desired.

Editor’s Tip: It is essential to check your tile material before using either of these solutions. Vinegar can be harmful to certain tile materials, such as marble, slate, granite, or stone tiles. It is advisable to avoid using vinegar if you have any of these tile types in your bathroom.
