One of the things we loved about our house when we bought it was all of the crown moulding and baseboards and other woodwork. It's painted white and it's the bane of my existence. I can't keep it clean! It looks so pretty when it's freshly painted, but it is just a collector of dog hair and dust. I try to vacuum as often as possible and dust it...but it just gets dirty over time. Any suggestions for keeping it clean that don't involve painting it annually?
