Can I clean black and green mold myself with bleach?« Back to Previous Page

It depends on the extent and cause. Small, surface-level mold on a non-porous skirting board, caused by a one-time spill you've already fixed, can sometimes be cleaned with a detergent solution. However, your situation with an active AC leak and visible spreading suggests a deeper issue.

Bleach is often ineffective on porous materials like wood, drywall, or carpet backing; it may bleach the surface color but leaves the root structure intact. In Dubai's high humidity, the mold will likely return quickly unless the moisture source is permanently resolved. The AC leak must be repaired first—this is non-negotiable.

For a recurring leak and spreading growth, a professional inspection is strongly advised. They can identify the exact mold type (which informs the cleanup protocol) and use moisture meters to locate hidden dampness within the wall or under the carpet. Remediation often involves removing and replacing the affected porous materials to prevent regrowth. A company with its own microbiology lab can provide the documentation needed to verify the space is truly safe again.
