Does anybody know how to wash dress trouser socks so they don't get pilled? I wash all of my clothes with Tide Coldwater in cold water and line dry my socks. No matter what I do however, and no matter how nice or new the socks, my socks develop little fuzzy pills. It's really upsetting because it makes them look dirty and old before their time. Does anybody have any advice for what to do short of hand washing them which I don't have time for? Thanks!
