The inside and outside of the cuffs can be cleaned without any problems. Use a microfibre cleaning cloth, a gentle cleaning agent and some water. After cleaning the cuff, dry it with a towel and let it dry carefully in the fresh air. 

Only when the last residual moisture has evaporated should you use the cuff again for massage applications.

It is essential to prevent moisture from entering the air chambers. To do this, you can also simply leave the air hoses connected to the cuff during cleaning.
