If your bathroom faucets are marred by ugly mineral deposits drop 2 denture-cleanser tablets into a cup of warm water. Soak a cloth in this solution and wrap around the faucet. Let this sit for about an hour. Now, using an old toothbrush or a non-scratch sponge to scrub the faucet. The effervescent cleaning agents in the denture tablets will dissolve the buildup for easy removal.
