If you haven't examined your medicine cabinet in months, this one's for you. Like closets, medicine cabinets benefit from a good purge every once in a while. Check the labels on your medications and dispose of anything that's expired. Did you find blue eyeshadow you haven't worn since the '80s? Chuck it. Once everything has been cleared out, scrub the shelves and neatly replace the contents. Consider magnetic paint to gain more storage on the inside door.
