Eucalan is recommended for WASHABLE sheepskins and furs. The tanning process determines whether the skin is washable or not. If you wash a skin that is not washable, the hide will become brittle and you will not be pleased with the results!
To determine if a skin is washable, check for a care label, contact the manufacturer or retailer you bought the skin from, or cut off a small piece of the skin and place it in water for a short time. Allow it to dry away from direct heat or sunlight. Once dry, if the skin is pliable and the fur/wool does not pull out and looks good, you can go ahead and wash the whole skin.
Sheepskins: eg. rugs, seat covers, slippers, mittens, vests, pillows
Leather: (eg.couch, pillow, jacket)
