Abstract
A method to clean a discharge port surface of a recording apparatus includes applying a cleaning liquid to the discharge port surface by a cleaning liquid application unit. The discharge port surface includes a discharge port line, a hydrophilic part, and a water-repellent part located between the hydrophilic part and the discharge port line. A plurality of discharge ports to discharge a liquid is aligned in a first direction. The hydrophilic part is provided separated from the discharge port line and protrudes from the discharge port surface in a discharge direction of the liquid from the plurality of discharge ports. After the cleaning liquid is applied to the discharge port surface, a cleaning liquid removal unit removes the applied cleaning liquid in a state where the cleaning liquid has been moved onto the hydrophilic part.
