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

Based on the symptoms you've described—black patches on the wall behind clothes from an AC leak—this is a classic scenario we encounter daily in Dubai's humid climate. The first and most critical step is to STOP. Do not attempt to clean it yet.

The AC leak is the root cause. You MUST get your building's maintenance team to inspect and repair the AC unit's drainage system immediately. This is non-negotiable. Under Dubai Municipality regulations, building owners are responsible for maintaining AC systems to prevent such moisture issues that lead to mold, which is considered a public health concern.

Until the leak is fixed, any cleaning is a temporary and potentially hazardous solution. The moisture will simply return, and the mold will regrow. Furthermore, disturbing the mold by cleaning can release a high concentration of spores into the air, which you and your family would then inhale. For small, surface-level patches (less than 10 square feet), a solution of white vinegar or a specialized mold cleaner can be used with proper PPE (N95 mask, gloves, goggles). However, given its location behind items and the duration (2 years), there is a high probability the mold has penetrated the gypsum board or backing of the closet.

For your family's safety, I strongly recommend a professional inspection. We can conduct air and surface sampling to identify the spore type and concentration to determine the correct remediation protocol. Attempting a DIY fix on what could be a deeper problem is a health risk.
