Drain no drain up.
Is there any good, thrifty, poor-skills-y way to make a slow drain drain well? The bathtub one, in our apartment, takes most of an hour to clear after a shower. We've been dousing it with Drain-O once a week; it lasts a few days and then the drain goes right back to stupidity. We're purchasing a hair-trap today (one of the ones that fits over a drainhole and catches the hair before it goes down), but I'd like to know: Is there anything cheap that works well?
