Washing. The unique tanning process that the sheepskin goes through enables your sheepskin rug to be hand or machine-washed. It is important not to use hot water when washing, however, as this may damage the pelt of the sheepskin. To hand wash, use a mild liquid household detergent in cold water.hen you're ready, dust off the corn starch and use a suede brush to brush the nap of the suede. If your coat has a napa finish, do not brush with a suede brush; rather, rub lightly with a soft towel. We do not suggest having your sheepskin dry-cleaned, as the treatment removes the garment's natural oils.
