How to safely clean mold without worsening cough?« Back to Previous Page

My kids have been coughing and I suspect it’s from the black spots I just found behind the wardrobe in our master bedroom. It's on the wall facing the outer corridor, which is always colder, and we’ve been running the AC non-stop for months. What's the safest way to clean this without making their coughs worse?

Based on the symptoms you're describing, especially with young children involved, it is critical to proceed with extreme caution. That persistent cough is a classic indicator of mold spore exposure, and improper cleaning can aerosolize those spores, making the situation significantly worse.

First, understand that the black spots behind the wardrobe are a symptom of a condensation issue, very common here in Dubai due to the constant AC use creating a thermal bridge on that cold outer wall. You are right to be concerned.

For a very small area (less than 1 square foot), you can attempt to clean it safely. However, this is a temporary measure and the root cause must be addressed.

Safety Protocol for DIY Cleaning:

1. Isolate & Protect: Keep the kids and anyone with respiratory issues completely away from the area. Seal the room by closing the door and placing a wet towel at the base. Wear an N95 respirator (not a simple dust mask), goggles, and disposable gloves.

2. Suppress Spores: NEVER dry brush or vacuum the mold, as this will blast spores into the air. Lightly mist the area with water from a spray bottle to dampen the spores and prevent them from becoming airborne during cleaning.

3. Clean: Use a solution of diluted detergent (like a few drops of dish soap in water) or a specialized, non-bleach-based mold cleaner. Gently scrub the area with a disposable cloth. Avoid bleach; it only bleaches the color but does not kill the root structure, and its fumes are a severe respiratory irritant.

4. Dispose & Dry: Place all used cleaning materials in a sealed plastic bag and dispose of it immediately outside your home. Use a dehumidifier or increase AC cooling to thoroughly dry the wall afterwards.

Given that your children are already symptomatic, this indicates a potential airborne contamination issue that DIY cleaning cannot resolve. The safest course of action is a professional inspection. We use thermal imaging to identify the exact moisture source and air testing to determine spore counts and species, which is crucial for health. Remediation then involves advanced containment and air scrubbing to ensure the environment is truly safe.

For your family's health, I strongly recommend you get a certified assessment. Call our team at 800-MOLDS (800-66537) or email hello@saniservice.com for a consultation.
