First, turn the volume control fully clockwise to ensure cartridges are closed. Next, pull of handle and shroud. Loosen the screw?æon the handle carrier to remove it. do the same for the clutch cover. Pull out clutch drive shaft and loosen screws to release clutch gears and back plate. Cartridges can be seen now and remove them by turning counter clockwise. Brush them and soak in vinegar to clean. Because these are made of ceramic, they don't require regular cleaning.
