The triple threat of mild abrasive, detergent, and antibacterial agent gives toothpaste stain-fighting power all over the house. Pat a bit onto chrome faucets and taps, then buff to a shine. To get silverware from tarnished to twinkling, squeeze a smidge onto a clean cloth and rub, then rinse with water and dry. And for water rings on wood, apply toothpaste with a damp cloth, then buff with a dry rag. The only caveat for these tricks? Use plain toothpaste, not gel or fancy whitening formulas.
