When I was growing up, we did not have a washer or dryer, so every friday we went to grandma's and washed in her machines. My aunt and uncle did the same thing on tuesdays. So whenever grandma needed to replace a worn out washer and dryer, we usually chipped in and bought it for her.
That being said, my school gym uniform would get pretty ripe after a couple days, so I brought them home and washed them in the sink, like MG described, hung them to dry. Like MG said, gotta keep up on it, would not want to wash 4-5 days worth of laundry in the sink all at once.
