These sleeves can be washed. Wash similar items together. Rinse gloves first in cold water, if pre-soaking use warm water. Wash using a milk soap or detergent in warm water, temperature not to exceed 160 degrees for no longer than 15 to 20 minutes. Rinse in cold water at a high speed. Tumble dry at no higher then 150 degrees for 15 to 20 minutes. Hope this helps!
