Safest way to clean black mold in Sharjah apartment?« Back to Previous Page

The safest approach depends on the size and location. For a small patch (under 1 square foot/0.1 sq m) on a non-porous wall, you can clean it yourself with precautions. For anything larger, or if it's on drywall or behind furniture, a professional inspection is strongly advised to assess the extent and potential hidden growth within the wall cavity.

In Sharjah's high humidity, that mold likely grew from condensation where the cold wall meets the humid air, a common issue exacerbated by year-round AC use creating constant temperature differentials. Your children's persistent coughs could be a reaction to the mold spores now airborne in the apartment.

To clean a small area safely, first ensure the room is well-ventilated; open windows and use a fan to blow air outward. Seal the area from the rest of the home and keep children and pets away. Wear an N95 mask, goggles, and rubber gloves. Scrub the area with a mixture of detergent and water. Avoid using bleach, as it doesn't prevent regrowth and can irritate the lungs further. After cleaning, the wall must be dried completely within 24-48 hours using a dehumidifier or fan to prevent immediate regrowth.

However, simply cleaning the surface is often insufficient. The root cause is the moisture. You must identify and rectify the source, which could be a plumbing leak, capillary rising damp, or chronic condensation from the AC's temperature setting being too low for the room's humidity level.

Given the described size ("huge patch") and the correlation with your children's health symptoms, a professional assessment is the most prudent course. They can perform a moisture survey to find the water source, assess the wall for penetration, and verify the mold species. Proper remediation involves containment, HEPA vacuuming, and antimicrobial treatment to ensure spores are not spread throughout your home during cleaning.
