When I first moved out of my parents and into a tiny studio I refused to use the landlord's washing machines and dryers in the basement of the building for some inexplicable reason so I hand washed my clothes and bedding and air dried them. My comforter was too big for the sink so I cleaned it by getting undressed, putting detergent on it, and wrestling it in the (standing) shower until it was thoroughly soaked and soaped. Then I'd rinse it off and wring it out as much as possible and hang dry it.
