Clean Tile Grout
Tackle tough-to-clean grout with hydrogen peroxide. Grout is made of porous cement which can be eroded by using harsh chemicals found in typical household cleaners. Ordinary household hydrogen peroxide helps whiten and clean without damaging delicate grout, plus its fumes are way less irritating than bleach. Spray on, wait 30 minutes, and scrub with a stiff-bristled brush, according to HomeTalk.com.
