All Active Hands gripping aids are machine washable. The gripping aids, thumb protector and heavy duty gripping wrap can be washed at 40°C on the synthetics setting in a washing machine (please remove the hook from the Hook aid before washing). Please ensure that the velcro is closed before washing to reduce the risk of it catching on other items of clothing. They must not be ironed, chlorine bleached, dry cleaned or tumble-dried.
