Editor's Pick: That ring of water stains and hard water marks inside the toilet bowl means scrubbing every few days. Just drop this into the tank, and every flush gives it a quick clean so everyday stains don't stick to the sides. One block lasts about four weeks, so three blocks will keep you covered for a good long while.
