Yes, the Kids Mattress Encasement includes quick and easy care! We recommend machine washing your Mattress Encasement on a cold, gentle cycle with like colors. Please do not dry clean, bleach, or iron, as these can damage the waterproofing layer. For small spills, we recommend spot cleaning with cold water and a mild household detergent or diluted cleaner.
