How to safely remove mold from AC leak?« Back to Previous Page

Alright, so you've got a classic AC leak situation leading to mold growth. It’s incredibly common here in Dubai due to our high humidity levels, especially with AC units working overtime. Here’s a safe, professional-grade approach for a DIY clean-up, but with a major caveat first.

First, assess the size. If that patch behind the wardrobe is larger than a square meter (about 10 sq ft), or if there's a musty odor in the room, this is no longer a DIY job. UAE civil defense regulations and best practices dictate that larger infestations require certified professionals for proper containment and remediation to prevent cross-contamination. If you're unsure, get a pro inspection.

For a small patch, here's the protocol. SAFETY FIRST. You need an N95 mask, nitrile gloves, and safety goggles. Do not skip this. Mold spores are allergens and irritants.

Move the wardrobe to fully expose the area. The goal is to remove the mold, not just bleach it white. Mix a solution of detergent and warm water (a squirt of dish soap works) and scrub the area with a stiff-bristled brush. This physically removes the biomass.

After scrubbing, disinfect the area. A Concrobium-based spray is ideal as it leaves an antimicrobial layer that helps prevent regrowth. Avoid chlorine bleach; it’s mostly water, the chlorine gas evaporates quickly, and it doesn't kill the roots. It also can't be used on porous surfaces like drywall, which you likely have.

The most critical step is addressing the source. You MUST fix the AC drain line leak. No amount of cleaning will work if the moisture source remains. Call your building maintenance or an HVAC technician to unclog and service the unit.

Finally, improve air circulation in that area. Keep the wardrobe slightly away from the wall and ensure your AC is set to a consistent, low humidity level.

If you’ve cleaned it and the patch returns quickly, or if you just want the peace of mind that it’s been handled to the highest standard, give our team a call at 800-MOLDS or email hello@saniservice.com for a proper assessment and hygienization certificate.
