Toothpaste is one versatile product. Next time your kids decide to display their "artwork" on the walls, grab a tube of toothpaste. Simply squeeze the paste on a rag and scrub until the marks disappear. This works on Crayloa-type markers as well as ballpoint and felt-tip pens.
Cost: $3-$5 for a tube of toothpaste
Savings: About $35 for a gallon of paint, new roller, and paint-tray liner.
