Open velcro and remove foams. Foam inserts are not machine washable. (See below for foam care.) The velcro opening is usually located along the top front edge of pad. Sometimes it is located along the top spine edge of pad. Close velcro after removing foam. Close any open velcro such as girth straps to prevent the velcro from snagging on any other materials. All Velcro must be closed and secure so it doesn't flop around in the washer.
