Can I clean AC wall mold myself or need professional?« Back to Previous Page

The black spots spreading from your AC leak are almost certainly mold, and Dubai's high humidity accelerates its growth dramatically. For a small area (under one square foot), you can attempt cleaning with a dedicated mold cleaner or a diluted bleach solution, but bleach only removes surface discoloration and does not kill the root structure penetrating porous materials like drywall.

Given the leak is ongoing and the mold is spreading behind furniture, this indicates a persistent moisture issue. The wall cavity itself may be contaminated, which you cannot see or effectively treat yourself. In the UAE, professional remediation is strongly advised for anything beyond a tiny, superficial patch. The process involves stopping the AC leak at its source, safely removing affected porous materials, using HEPA filtration to contain spores, and applying EPA-approved antimicrobials. A proper assessment, often involving moisture meters and sometimes air testing, is crucial to determine the full extent. Companies with their own microbiology labs can provide definitive identification and post-remediation verification to ensure the environment is truly restored to a healthy state.
