Can I clean mold under my AC with bleach?« Back to Previous Page

Cleaning that mold with bleach is a common first thought, but it's not the recommended solution, especially in Dubai's climate. Bleach is mostly water, and its chlorine component evaporates quickly off porous surfaces like concrete and carpet backing. This can leave the moisture behind, which will actually feed the mold again within days. The visible patch is also just the surface growth; the root structure (hyphae) is likely deeper within the material.

For a small, surface-level patch, a more effective DIY approach is to use a dedicated EPA-approved fungicide or a simple solution of distilled white vinegar. However, the critical factor here is the leak and the hidden damage. Two weeks of continuous moisture from an AC leak has almost certainly wicked into the concrete slab and the carpet underlay, creating a perfect breeding ground out of sight. In Dubai's high humidity, this allows for rapid, unseen colonization.

You should absolutely address the AC leak immediately to stop the moisture source. For the mold itself, given its location on a porous surface and the duration of the leak, professional assessment is strongly advised. Proper remediation involves removing the affected carpet and underlay, HEPA-vacuuming the area, and sanding the concrete to remove the fungal roots, followed by antimicrobial application. A professional inspection can confirm the extent of the damage and ensure it is handled correctly to prevent recurrence and potential health issues from airborne spores.
