How to stop black mold on leather in humid closet?« Back to Previous Page

My bedroom closet on the outside wall has started getting these black speckles on my leather bags and shoes. I first spotted it a couple of weeks ago and wiped it away, but it’s already coming back even though I keep the AC running. I’m really worried it’s going to ruin my stuff and spread. What’s the most effective way to treat this and stop it for good, especially with our humid weather here?

That black speckling is almost certainly mold, and it's a common issue in Dubai's climate. The problem isn't your leather items themselves, but the humid micro-climate inside that closet, especially if it's on an outside wall which can be warmer.

First, move your affected items to a dry, well-ventilated area immediately. For the leather, wipe it down with a soft cloth lightly dampened with a 50/50 mix of water and white vinegar or a leather-safe disinfectant. Let items dry completely away from sunlight before storing again.

To stop it from returning, you must address the humidity source. The closet is likely a condensation hotspot. Ensure the room's AC vent isn't blocked and that cold air can circulate into the closet; leaving the closet door ajar can help significantly. A standalone dehumidifier or moisture-absorbing products like silica gel packs placed inside the closet can also help reduce the dampness that mold thrives on.

For a persistent problem, a professional inspection is wise. They can use a moisture meter to identify hidden dampness in the wall or check if a leaking AC pipe inside the wall is the culprit. In many cases, the most effective long-term solution is installing a small duct to channel dry, cooled air from your AC directly into the closet space, creating an environment where mold cannot survive.
