Abstract
A dialysis system includes a dialysis device, a flow path through which a dialysate supplied to the dialysis device or a liquid component for adjusting the dialysate flows, and a cleaning liquid supply portion for supplying a cleaning liquid to the flow path. The cleaning liquid supply portion has an acid supply portion for supplying an acidic cleaning liquid (a) to the flow path, and an alkali supply portion for supplying a cleaning liquid (b) containing sodium hypochlorite to the flow path. A cleaning method of the dialysis system includes a first cleaning process in which the inside of the dialysis device is cleaned with a cleaning liquid (a+b) obtained by mixing the cleaning liquid supplied from the acid supply portion and the cleaning liquid (b) supplied from the alkali supply portion.
