Another line of defense for the skin is the prosthetic sheath. Acting as an interface between the skin and the prosthetic sock, the sheath also should be changed and laundered daily. Just as in washing the socket and prosthetic socks, the sheath should be lathered with a sanitizing lotion or mild detergent, using warm water. After generous rinsing in warm, clear water, it should be squeezed, but not wrung out, and left to dry completely. Most sheaths are manufactured from artificial fibers, indicating delicate handling. The material air-dries quickly and should be ready to wear the following day.

To prolong the life of prosthetic socks and sheaths, always dry them naturally; do not put them in a dryer.
