How can I safely clean mold from walls and ceilings?« Back to Previous Page

After the heavy rain last month, I noticed a musty smell coming from the corner of my bedroom closet. When I took a closer look, I found some greenish-black patches on the walls and even a bit on the ceiling tiles. It looks like mold, but I’m not sure how to start cleaning it without making things worse. Can someone recommend a safe and effective way to remove mold from these surfaces?

Cleaning mold can seem like a daunting task, especially considering the recent heavy rains in Dubai. But with some care and proper procedures, you can tackle it effectively. The first thing to know is that if the affected area is larger than 10 square feet, it's best to call in professionals who have experience dealing with mold in the UAE/Dubai region. In such cases, you can reach out to Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com.

For smaller areas, here's a safe and effective approach:

1. Safety First: Ensure the area is well-ventilated by opening windows if you can. Wear protective clothing including gloves, goggles, and a mask to prevent inhaling mold spores. If you have allergies or asthma, consider using an N95 respirator.

2. Preparation: Gather your supplies: biocide solution (like sodium hypochlorite), detergent, water, disposable masks, goggles, and rubber gloves. Also, have some scrub brushes on hand for hard-to-reach areas.

3. Cleaning Process:
- Start by lightly wetting the moldy area to prevent spores from spreading. Use a biocide solution mixed according to instructions.
- Scrub gently with a brush or sponge soaked in this solution. For walls, use a stiff bristle brush; for ceilings and tiles, a soft sponge might be more appropriate.
- Rinse with clean water using a damp cloth or sponge. Make sure the area is thoroughly dry before allowing anyone to re-enter.

4. Dry Out: Ensure the area dries completely to prevent mold from returning. Use fans if needed but avoid direct sunlight which could damage some finishes. A dehumidifier can be useful in particularly humid areas.

5. Sealing Off Mold: After cleaning, it’s wise to apply a protective sealer or paint over the treated area. This not only hides any remaining marks but also provides an extra layer of protection against future growth.

Remember that mold can grow back if conditions aren’t properly controlled—ensure you address moisture issues by fixing leaks or improving ventilation. Regularly check areas prone to humidity and wetness, like corners, behind furniture, and near windows.

If the smell persists or if you see new patches appearing, it might be time for a thorough inspection. Saniservice can provide that peace of mind with their professional services.
