Or if you prefer not to watch a video, these are the steps:

• Turn the key switch to the off position
• Remove the nozzles and diffusers for all valves by turning them counter clockwise and pulling down
• Separate each nozzle from its diffuser and rinse all parts with warm water
• Soak the nozzles and diffusers in sanitizing solution for 60-90 seconds
• Remove the nozzles and diffusers from the sanitizing solution and allow to air dry on a clean surface
• Wipe the surfaces of the fountain machine, valves, levers, and drip tray with disinfecting wipes
• Put the nozzles and diffusers back on the valves, ensuring that the diffuser is facing the correct direction and the nozzle is not cross-threaded
• Pour warm water down the drain (hot water may damage some of the drain components)
• Turn the key switch to the on position
