How to treat moldy leather items and prevent future growth?« Back to Previous Page

Treat the affected leather items immediately with a solution of 70% isopropyl alcohol and 30% distilled water. Dampen a soft, white cloth with the solution and gently wipe the mould off. Wipe again with a cloth dampened with only distilled water, then allow the items to air dry completely away from direct sunlight, which can damage the leather. For valuable items, consulting a professional leather conservator is recommended to avoid damage.

The root cause is the high humidity in that enclosed space, a common issue in Dubai where constant AC can create cold spots that lead to condensation on outside walls. A dehumidifier is essential. For a small, enclosed closet, a compact desiccant dehumidifier is more effective than a refrigerant model in our climate, as it works better in the cooler temperatures maintained by AC. Look for a unit with an auto-humidistat to maintain humidity below 55%, the level where mould growth is inhibited.

First, however, you must identify and address the moisture source. The mould on an outside wall suggests condensation due to the temperature difference between the cold interior and the hot, humid exterior. This could indicate insufficient insulation or a potential breach in the vapour barrier. Wiping the wall with a mould-inhibiting cleaner is a temporary fix. For a permanent solution, a professional inspection can identify if wall cavity moisture or insulation issues require remediation to stop the cycle of condensation and mould regrowth.
