Abstract
A method of cleaning medical instruments comprises the steps of placing an instrument in an enclosure and subjecting the instrument to a cleaning phase in which a cleansing solution is applied to the surfaces of the instrument, a disinfection phase in which a disinfection solution is applied to the surfaces of the instrument, a rinsing phase in which a flushing solution is applied to the surfaces of the instrument, a purging phase in which a volatile liquid is applied to the surfaces of the instrument and a drying phase in which a drying gas is passed over the surfaces of the instrument. The method is particularly suited for use with endoscopes.
