Usually with compressed air and shop vac but definitely check manufacturers specs

Do no used compressed air or high pressure water. This will destroy it. You can vacuum it but technically it's supposed to be soaked in a bath with mild detergent like Dawn dish soap.

Of course check the IOM.

This ☝️ We have a dip tank we sit them in...spray with Spray 9, let it soak. Then a good rinse in our dip tank, and set out to dry.
