Causes of mould growth on rubber

Mould can develop on rubber when conditions are favourable. In practice, this is usually linked to the following factors:

Moisture: Prolonged exposure to water or damp increases the risk of mould growth.
Poor ventilation: Poorly ventilated spaces allow moisture to linger.
Storage conditions: Rubber stored in warm, damp environments is more prone to mould.
Temperature: Heat combined with moisture encourages mould growth.

To help limit mould growth in future, we recommend cleaning the rubber regularly, allowing it to dry thoroughly and ensuring adequate ventilation. Store rubber in a cool, dry place where possible and always follow the manufacturer's care instructions. Regular maintenance and proper storage conditions are key to preventing mould from returning. By taking these preventive measures, you can extend the life of your rubber items and maintain a healthier environment.
