Wash in the washing machine in the cold water setting with laundry detergent. We don’t recommend using bleach as it’s too harsh on the fabric fibers. The Zip-n-Wash cover can be washed together with your sheets and pillowcases too - no need to keep separate. Only wash the top (white) part of the mattress cover. Tumble dry low or air-dry flat for best results. We don’t recommend dry cleaning or ironing. Check out our blog post for more tips on caring for your Zip-n-Wash cover!
