For a small, surface-level area (under 1 square meter), a cautious DIY approach may be possible. Begin by moving the wardrobe to fully expose the area. Wear an N95 mask, gloves, and safety glasses. Clean the affected hard surface with a solution of detergent and water, then wipe with a diluted bleach solution (1 part bleach to 10 parts water) to disinfect. It is critical to identify and rectify the moisture source. This is likely due to condensation from the AC unit or a lack of ventilation. Ensure your AC is serviced and draining properly, and improve air circulation in the room.

However, given that you’ve noticed a persistent damp feeling and the issue has worsened with recent humidity, I strongly recommend a professional inspection. The visible mold is often just the “tip of the iceberg,” and the hyphae (root structures) can penetrate porous materials like drywall. Improper cleaning can aerosolize spores and spread the contamination. Professionals use moisture meters, thermal imaging, and specialized containment and air filtration equipment to safely remediate the issue and ensure it does not recur, in line with IICRC standards for mold remediation.

For a definitive diagnosis and a guaranteed solution, especially in a sensitive area like a bedroom, contacting a specialist is the most effective and safest course of action.
