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

That black spotting is a classic sign of mould growth, almost certainly caused by the moisture from your AC leak combined with Dubai's high ambient humidity. The most effective approach addresses both the symptom (the mould) and the root cause (the leak and moisture).

First, for the wardrobe mould: For a small, surface-level area, you can clean it yourself. Wear an N95 mask and gloves. A solution of white vinegar or a dedicated mould-cleaning product applied with a scrub brush is often effective. Do not use bleach, as it only removes the colour and can push spores deeper into the material. Dry the area thoroughly immediately after cleaning with a fan to prevent immediate regrowth. However, if the mould has penetrated the wood or the affected area is larger than a square foot, the porous material may need to be professionally treated or replaced to fully resolve the issue.

The critical step is fixing the AC leak. This is not a DIY job. You need a certified HVAC technician to diagnose the source—common causes here include a clogged condensate drain line, a damaged drain pan, or improper insulation causing excess condensation. They will repair the leak and ensure the unit is draining properly. Merely cleaning the mould without stopping the water source guarantees it will return.

For verification and to ensure the space is healthy, consider a professional indoor air quality assessment. A company with its own microbiology lab can test to identify the mould species and confirm remediation was successful through post-cleanup air sampling, which is particularly valuable for peace of mind in a bedroom.
