The makers of Goo Gone from Magic American Corp. claim their citrus-based formula can remove tree sap, bird droppings, brake dust, tar, spray paint, bumper stickers and other nasty stuff from your vehicle’s exterior. But that’s not all. Goo Gone can also go to work on the inside to take care of a variety of stains and spills on your upholstery, or any cloth, glass, or plastic surface for that matter. (It’s not recommended for leather and rubber). A 16-ounce bottle sells for $11, or pick the 12-ounce spray gel for $7.50. Order either or both (or any of the other Goo Gone cleaners for around-the-home use) at www.googone.com.
