Mold prevention in closets requires addressing humidity and ventilation

Addressing mold in closets requires identifying root causes rather than relying on superficial solutions like perfumes, scented sachets, or baking soda, which only mask odors. Mold is caused by fungi thriving in humid, poorly ventilated environments. Common issues include active infiltration or condensation caused by cold walls in contact with internal heat.

In humid climates, such as in Pará, closets placed against external walls are particularly susceptible. Mold often appears first on the back of the furniture because the narrow, dark space between the wood and the wall prevents air circulation, trapping moisture. To prevent this, maintaining a small gap—approximately 5 centimeters—between the furniture and the wall can facilitate airflow and drying.

Effective management involves emptying the furniture to inspect for dark spots, peeling paint, or texture changes in the wood. Additionally, ensuring that clothes are completely dry before storage is vital, as residual moisture in dense fabrics can create a greenhouse effect that promotes fungal growth.
