In The New World on Mars, @robert_zubrin suggested that colonists could wash their clothes by just exposing them to the outside near-vacuum. It wouldn’t remove stains, but it would clear the stink. Trista was extremely skeptical, but I got out the vacuum pump and we ran the experiment. After 15 minutes, it hadn’t made much difference. However, after an hour, the dirty clothes smell was sensibly reduced. Probably needs a few hours to completely clear.
