Machines vary, but a routine cleaning schedule can be applied to most devices. First, unplug the machine and disconnect the tubing and mask. Separate the mask into its three parts: headgear, frame, and cushion. You can clean the headgear and mask cushion in a sink or bathtub by gently rubbing warm water and soap onto it. Avoid strong products like dish detergents, choosing a gentle facial soap instead. Rinse thoroughly and put the frame and cushion on a flat surface to dry, avoiding direct sunlight.
