How to remove closet mold and prevent moisture?« Back to Previous Page

Our master bedroom closet, which is on an interior wall, has started getting these black speckles on the leather bags and shoes I have stored in there. It’s been really humid the last few weeks and even though the AC is always on, that closet feels damp and has a weird, earthy smell. What’s the best way to get rid of this mold for good and what can I put in there to stop the moisture from building up again?

Based on your description, that's classic mold growth, almost certainly caused by the high humidity we've been experiencing here in the UAE. The earthy smell is a dead giveaway. For a closet on an interior wall, the issue is likely insufficient air circulation, allowing moist air from the room to become trapped and condense on cooler surfaces.

For DIY removal on those leather goods, first take them outside. Use a soft brush to gently remove the dry spores. Then, wipe them down with a cloth slightly dampened with a leather-safe cleaner or a solution of equal parts water and 70% isopropyl alcohol, testing on an inconspicuous area first. Allow them to dry completely in a well-ventilated area, not back in that closet.

For the closet itself, you need to address the source. Thoroughly clean all interior surfaces with a detergent solution. Do NOT use bleach, as it doesn't kill roots and can worsen indoor air quality. The critical step is moisture control. You must improve air flow. Leave the closet doors open and consider installing a small battery-operated dehumidifier or a renewable desiccant like silica gel packs. Ensure your AC unit is serviced and draining properly, as a faulty unit can actually contribute to humidity.

However, surface cleaning doesn't address potential hidden growth inside the wall. Given the persistent dampness and smell, this is a case where a professional inspection is highly recommended. We use thermal imaging and moisture meters to find the exact source of the moisture intrusion, which is essential for a permanent fix. Improper handling can aerosolize spores and spread the problem.

For a proper assessment and remediation plan, feel free to give us a call at 800-MOLDS or email hello@saniservice.com. We can determine if this is a simple ventilation issue or something more serious.
