Ah, the perfection of a hot, steamy shower. It's a cure-all for early mornings, short nights and excessive study sessions. Until, that is, the showerhead's functionality regresses from steady waterfall to few paltry sprinkles. Over time, mineral deposits will begin to clog a showerhead, making it far less useful than it once was.
Don't be surprised if the showerhead in the dorm bathroom doesn't get a lot of attention from the weekly cleaning crew or your floormates. What you should be (pleasantly) surprised about is how easy it is to clean. Pour white vinegar into a plastic baggie and seal the bag around the showerhead. Let it sit overnight and then use an old toothbrush to scrub off the residue. You'll feel like your next shower is in a tropical waterfall (as long as you have a good imagination) [source: Martha Stewart].
