Can I fix closet mold with vinegar and a dehumidifier?« Back to Previous Page

My walk-in closet in our Jumeirah apartment has started to feel damp, and I’ve just found a few small black spots on a couple of leather bags in the back corner. It's been insanely humid the past few weeks and I’m worried it’s spreading. Is this something I can tackle with a vinegar spray and a dehumidifier, or do I need to call in a professional cleaning service before it gets worse?

Good question. This is a very common issue here in Jumeirah, especially with the recent spike in humidity we've been having.

While vinegar (distilled white, 5-10% acidity) is a mild fungistatic agent and a dehumidifier is absolutely essential for prevention, your approach may not be sufficient for a few key reasons. The visible spots on the surface are just the reproductive structure of the mold; the root system (hyphae) is likely embedded deep within the porous leather and any underlying drywall or backing. Vinegar will only superficially clean the surface without addressing this root colonization. For valuable items like leather goods, improper cleaning can cause permanent damage.

In the UAE's climate, the primary cause is nearly always excess moisture. Before any cleaning, you MUST identify and rectify the source. In closets, this is often due to a lack of air circulation, a nearby bathroom's humidity migrating through the walls, or even a small, hidden plumbing leak.

My professional recommendation is this: For now, isolate the affected bags in a sealed bag to prevent cross-contamination. Run a high-capacity dehumidifier in the room immediately to get the relative humidity below 60%. However, given you already see growth on materials, this is a sign of an established problem.

For a definitive solution and to ensure it doesn't spread or cause health issues, a professional inspection is strongly advised. We use thermal imaging cameras and moisture meters to pinpoint the exact moisture source and assess the full extent. Attempting to remediate without this knowledge often leads to recurrence.

Call us for a professional assessment. We can determine if this is a simple surface issue or something more serious. Call 800-MOLDS or email hello@saniservice.com for a consultation.
