Two similar representative versions of an eye glass cleaning machine constructed in accordance with the principles of the invention are seen. In each version an enclosure providing a base having a bowl forming an eye glass cavity supports a pair of eye glasses to be cleaned by means of adjustable clips. In the first version of the invention, a heated cleaning fluid and waste fluid tank and a rinse water tank are filled by a two-way drain valve. In the second version, a heated cleaning fluid tank, a rinse water tank and a waste tank are filled by a three-way drain valve. In both versions of the invention, an electronics card controls the operation of a pump, air pump and a solenoid valve, which determines from which tank (cleaning fluid or rinse water) the fluid supplied to spray nozzles will be taken. The electronics also controls heating elements in the cleaning fluid and rinse water tanks. The adjustable two-way or three-way drain valve allows the user to rotate a valve plate having a hole until it coincides wit h the appropriate fill port.
