If there is mold growing on your Air Sprung Cell sleeping mat, you should first clean the mat thoroughly with warm water and mild soap. After cleaning, let the mat dry completely before packing it away.
To prevent mold growth in the future, it is important to store your sleeping mat in a dry and well-ventilated area. Make sure the mat is completely dry before storing it. If possible, store the mat unrolled and loosely folded to allow for air circulation.
If the mold growth is severe and the cleaning process does not eliminate it, it may be necessary to dispose of the mat and replace it with a new one.
