Once there was a forgotten creature that thrived in dark, dank solitude. As it grew, it became greedier, expanding its reach until it could be ignored no longer.
Sound like the plot of a thriller opening in theaters this weekend? You wish. This is actually the true story of the germ-ridden gunk that lives behind the sink and faucet in your dorm bathroom. Fortunately, it's incredibly easy to fight back. Get rid of the bacteria-laced mineral deposits or mildew by adding one simple step to your bedtime routine.
Once a month, soak paper towels in white vinegar and wrap them around the faucet. Make sure the back of the faucet is completely covered. Let them rest overnight, then peel off the towels. Fill the sink with warm water, add a bit of soap and use an old toothbrush to scrub the faucet to remove any remaining residue. As a bonus, you'll also have a clean and shiny sink basin [source: Reader's Digest].
You can also take that old toothbrush, dip it in bleach and scrub behind the sink.
