<p>[PROBLEMS] To provide a washing method capable of securely washing out water soluble stains such as sweat without damaging cloth. [MEANS FOR SOLVING PROBLEMS] A frame body (18) is horizontally disposed in a casing. The frame body (18) is rotated by a drive motor (23) in the casing. The casing and the frame body (18) are filled with a washing fluid, and clothes are stored in the frame body (18). A plurality of protruded rings (40) are formed on the inner peripheral surface (39) of the frame body (18) so that the inner peripheral surface is corrugated. The height dimension of the protruded rings (40) is set to 3.0 to 6.0% of the inner diameter dimension of the frame body (18). When the frame body (18) is rotated, the clothes are brought into a nearly zero gravity state without touching the wall surface of the frame body (18). A surface active agent contained in the washing fluid deeply penetrates into the clothes.</p> |
