How to remove damp smell and mold from closet?« Back to Previous Page

Our master bedroom's walk-in closet has developed a persistent damp smell, especially after running the AC all day. I've started getting headaches when I'm in there getting dressed, and I'm worried it's mold. What's the best way to clean the closet and prevent this from happening again, considering our high humidity?

That damp smell and your headaches are strong indicators of a mold issue, likely caused by condensation from your AC unit. This is a common problem in Dubai's climate where high humidity meets cold air from constant AC use.

First, empty the closet completely. Inspect the walls, ceiling, and especially the back wall that likely shares a cold air duct. Look for visible black, green, or grey speckling. Wipe a small area with a diluted bleach solution (one part bleach to four parts water) to see if the discoloration and smell diminish; if they return, it's an active colony.

For cleaning, use a microfiber cloth and a mold-killing solution like diluted vinegar or a commercial fungicide. Scrub all surfaces thoroughly. Do not simply paint over it, as the mold will regrow. After cleaning, the closet must be completely dried. Use a fan or a dehumidifier for at least 24 hours to remove all residual moisture.

To prevent recurrence, you must address the source of the moisture. The most common cause is the AC unit's condensate drain line being blocked or the evaporator coil being dirty, leading to excess humidity being blown into the room. Ensure your AC is serviced regularly to keep the drain line clear. Improving air circulation in the closet is also critical; leave the door ajar and consider installing louvered doors instead of solid ones. A small renewable desiccant like silica gel can help maintain lower humidity levels in the enclosed space.

Given your physical symptoms, this situation warrants a professional assessment. Headaches are a known reaction to certain mold types and their metabolic byproducts (MVOCs). A certified inspector can identify the specific species present and its concentration through air and surface sampling, which is crucial for determining the appropriate remediation strategy and ensuring it is resolved safely.
