Vinegar made closet mold worse; call a professional?« Back to Previous Page

Based on your description, this is a clear case where you should stop all DIY attempts and immediately call a professional mold inspection company. The fact that the mold returned and spread after you applied vinegar is a significant red flag. Vinegar is a mild acid that can kill some surface-level mold but is completely ineffective against more resilient colonies and the deep-seated hyphae (root structures) within building materials. In Dubai's high-humidity climate, exacerbated by a leaking AC unit, you are dealing with a persistent moisture source, creating an ideal breeding ground for toxic black mold (like Stachybotrys chartarum), which your action has likely agitated and caused to release more spores.

The leaking AC is the critical issue. This is not just a surface problem; the moisture has likely penetrated the wall's core, and mold is growing within the drywall or insulation, which you cannot address with any surface cleaner. UAE regulations, particularly from Dubai Municipality, have strict guidelines for indoor air quality and mold remediation to protect occupant health, requiring professional assessment and containment procedures to prevent cross-contamination.

Attempting a stronger cleaner yourself is highly inadvisable. Agitating the mold further poses serious health risks from spore inhalation and risks spreading the contamination throughout your home via the HVAC system.

Our recommendation is to cease use of the AC in that closet, avoid the area, and contact a certified professional. Saniservice provides comprehensive mold inspection services, including moisture mapping and air quality testing, to identify the full extent of the contamination and the source of the moisture. Our remediation protocols follow Dubai Municipality standards to ensure the mold is safely and permanently removed.
