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.
