Simply remove the mouthpiece and handle cover and then drop the 3 pieces (mouthpiece, handle cover and body) into water with POWERbreathe cleansing solution. You could always just drop the whole thing in complete, but it would clean the POWERbreathe more thoroughly if you dismantled it into these 3 parts.

Cold water sterilisation only.

Not suitable for sterilisation by boiling, steam, microwave or oven.
