Can I clean mold behind furniture with bleach?« Back to Previous Page

My kids have been coughing for a couple of weeks and I just found a bunch of black spots behind the wardrobe in our master bedroom, which is right next to the AC unit. We’ve lived in this Jumeirah apartment for 2 years and just noticed this, probably because we never move that heavy furniture. Is this something I can clean myself with bleach from the supermarket, or do I absolutely need to call one of those professional mold removal companies?

It depends on the size and type of mold. For a small, surface-level patch (less than one square meter) that you've found early, a thorough cleaning can be effective. However, the proximity to the AC unit in a humid climate like Dubai's is a significant concern, as it suggests a persistent moisture source that must be addressed.

For a DIY approach, skip the standard household bleach. It is mostly water and can actually feed mold deep within porous materials like drywall or plaster, and its fumes are hazardous in enclosed spaces. A more effective solution is a mixture of distilled white vinegar and water or a dedicated, non-bleach-based mold cleaner. Scrub the area thoroughly, allow it to dry completely, and then monitor it closely for any regrowth.

Crucially, moving the wardrobe revealed a symptom, not the cause. The mold grew there due to excess humidity and condensation, likely from the AC system. Simply cleaning the spot without investigating the AC's drain pan, condensate line, or insulation will almost certainly lead to the mold returning. In apartments, this can sometimes be linked to central building systems.

Given that your children are experiencing respiratory symptoms, a professional inspection is strongly recommended. They can identify the specific mold species and, more importantly, locate and resolve the underlying moisture issue. In Dubai, proper remediation follows standards like the IICRC S520, which focuses on containing the area and removing the source to prevent spores from spreading to other parts of your home during cleaning. Verifying a company's certifications and their willingness to provide before-and-after testing data is the best way to ensure the problem is resolved for good.
