Bathroom mold is often caused by excess moisture on the walls and ceiling. To prevent mold from reoccurring, the first step is to eliminate the factors that contribute to moisture buildup and mold formation. Addressing these issues is crucial for maintaining a clean, healthy bathroom. Mold in bathrooms can be harmful to health. Below are some of the most effective methods to remove mold and prevent it from coming back.
How to Remove Bathroom Mold
1-Find and Eliminate the Source of Mold
Before cleaning bathroom mold, ensure that it won’t return. The moisture causing the mold often comes from water droplets that collect on the walls and ceiling after a shower. To combat this, ventilate the bathroom after each use. You can also use a bathroom exhaust fan to help expel moisture. Another cause of mold is plumbing leaks. Faulty pipes can create moisture on the walls, which leads to mold growth. Make sure to repair any plumbing issues before removing the mold. “Related article: Bathroom ceiling leaking water.”
2-Scrape the Mold Away
If the mold has already spread on the bathroom ceiling or walls, you may need to scrape it off. If the mold has penetrated deep into the surface, you might need to use a more aggressive sanding or scraping method. After completely removing the mold, use wall repair paste or plaster to fill in any gaps or uneven areas. Once dry, repaint the area.
3-Wipe Mold with Bleach
Mix one part bleach with three parts water. Apply this solution to the moldy area using a cloth or a spray bottle. Let the mixture sit for 20 minutes, then scrub the area to remove the mold. If the mold isn’t fully removed, repeat the process.
Tip: If the mold hasn’t penetrated deep into the walls, this method will work effectively. Be cautious not to increase the bleach concentration too much, as it can cause damage to the paint over time. “Related article: How to fix peeling bathroom paint?”
4-Use White Vinegar
Another great option to remove mold from bathroom walls and ceilings is white vinegar. Vinegar kills mold spores and helps prevent further mold growth. Pour vinegar into a spray bottle and apply directly to the moldy areas. Let it sit for about an hour, then clean the surface. If necessary, repeat the application.
5-Use Mold and Mildew Removers
Mold removers are one of the easiest ways to eliminate bathroom mold. Simply spray the product on the affected areas and wait 15-20 minutes, then wipe the surface clean. If mold remains, repeat the process. Tip: For mold that has penetrated the walls, it’s recommended to sand the area before using mold remover.
6-Use Mildew-Resistant Paint
After successfully removing mold from bathroom ceilings and walls, consider painting the area with mildew-resistant paint. These paints help prevent mold growth in the future. However, make sure not to apply the paint directly onto the moldy surface—first, thoroughly clean the area. Applying mildew-resistant paint on an untreated surface could lead to mold returning.
Other Tips
- Ensure Proper Ventilation: Make sure the bathroom is well-ventilated and that moisture doesn’t linger on the walls.
- Avoid Silicone-Based Paints: Do not use silicone-based paints on bathroom walls and ceilings, as they can reduce air circulation and promote mold growth.
- Choose Special Ceiling Paints: Use paints specially designed for ceilings, as they don’t contain materials like silicone and Teflon, which can restrict airflow. “Related article: Best paint for ceilings.”
