The washing machine does. Either this conversation has come full circle or HN, circus of productivity hacks, is exceptionally ineffective at doing laundry.
Are you being serious? My unwashed laundry only smells when you press your nose to it. In the hamper it’s fine for the 1-7 days it generally waits.
Although this thread has hit on an interesting method of distributing folding into daily tiny sessions - especially for the childfree, who produce just a single dirty outfit per day after all.
The method would be that you don’t own any clothes that wrinkle, and wash a load of laundry each week, then you hang up your towel, and just sit the clean basket by the dresser, and each morning before you get dressed, you also fold and put away (or wear) “n” items where “n” is the average number of items you wear each day. At the end of the week you should have an essentially empty “clean” basket and a new dirty basket. If you were very disciplined about this you could just have the basics in rotation at all times, meaning you only own like 8 pairs of underpants, 16 socks, etc. and those simply come out of the clean basket straight onto your body.
