I made it very clear that anything left on the floors (clothing, etc) gets a one-day grace period then it will be thrown away. Same with the few dishes he has as he would leave them in the sink until they started to grow mold. I started locking my bathroom door and he has to use the one in the basement which I refuse to clean. If his clothes are in the washer for more than 8 hours and I need to use it, I dump them wet on his bed.
