How to treat and prevent mold on leather in humid closet?« Back to Previous Page

First, move the affected leather items out of the closet immediately to a well-ventilated, air-conditioned space to prevent further growth. For cleaning, use a solution of one part white vinegar to one part water. Dampen a soft, lint-free cloth with the solution, wring it out thoroughly so it's only slightly damp, and gently wipe the mould off the leather. Follow up with a dry cloth to absorb all moisture. Never saturate the leather. For valuable items, consulting a professional leather restorer is the safest option to avoid damage.

To prevent recurrence, you need to address the humidity. In a Marina apartment with limited airflow, a small, plug-in dehumidifier or desiccant bags placed inside the closet are essential during the humid summer months. Leave some space between your stored items and the walls to allow for air circulation. Regularly run your apartment's AC, as consistent cooling also dehumidifies the air; a setting of 23-24°C is often sufficient for this purpose.

If the mould growth is extensive, has penetrated deeply, or you notice a persistent musty smell, a professional inspection can identify the source of moisture and the mould species. This is particularly important in multi-unit buildings, as the issue could originate from a neighbouring unit or a hidden leak in the building envelope, which would require management intervention.
