How to safely clean mould and prevent it returning?« Back to Previous Page

That black spotting is almost certainly mould, and the sneezing is a classic reaction. Dubai's high humidity, especially in less-frequented rooms, creates perfect conditions for it to grow behind furniture where air doesn't circulate.

For cleaning, first move the wardrobe away from the wall. Wear an N95 mask and gloves. For a small area, scrub the spots with a mixture of white vinegar or a dedicated mould remover, not bleach, as bleach only removes the colour and not the root structure. Allow the area to dry completely. Proper ventilation is critical during and after cleaning; open windows if possible or use fans.

To prevent its return, you must control the humidity. This is the most important step. That room likely has stagnant, humid air. Run a dehumidifier in there consistently, aiming to keep relative humidity below 60%. Leave the wardrobe slightly away from the wall to ensure air can flow behind it. If the room has an AC vent, ensure it is fully open and that cold air is actually reaching that corner; sometimes ducts need balancing.

Given the symptoms your children are experiencing, the mould colony may be more extensive than what's visible. Spores can travel through the air. For health assurance, a professional inspection with lab testing can identify the mould species and confirm the entire affected area has been addressed, which is particularly advisable with children in the home. They can also check for hidden moisture sources within the wall itself.
