To clean a steam iron, use cheap toothpaste (don't use the gel type). and wipe with a clean cloth. Toothpaste also whitens the rubber of tennis shoes, polishes leather shoes and chrome, lifts crayon off walls, lifts stains out of carpets, removes water rings from coffee tables and lipstick from fabric, cleans the sour smells from baby bottles, shines diamonds, removes small scratches from glass, and cleans enamel.
Every time I get my teeth cleaned, my dentist gives me sample toothpaste. I also have extra tubes that no one liked the taste of. I love these tips for using toothpaste:
Jewelry Polish: Out of the actual thing? Brighten tarnished baubles and precious metals by smearing them with a glob of non-gel toothpaste. Gently buff with a soft cloth until they shine.
Computer Cleaner: Get grubby fingerprints off the keys by rubbing them with a white, baking soda-based toothpaste. Let dry, then wipe with a damp cloth.
Swim-Goggle Defogger: Coat each lens inside and out with non-gel toothpaste and rinse. The paste helps prevent haziness.
Hand Deodorizer: After handling garlic or onions, apply a half dollar-size amount to wet palms, rub together, and rinse.
Nail Brightener: Gently massage a little whitening toothpaste into nail beds to remove any yellowing.
Shoe Shine: Return white or light-colored kicks to their fresh-out-of-the-box state by erasing scuff marks with a soft toothbrush and a white non-gel paste. Remove excess with a damp cloth.
