Handheld steamers heat water fast to create a powerful blast of steam that can sanitize surfaces and get gooey, pesky dirt out of tight places. Steamers make short work of the gunk around the lip of the sink, the glop on the range hood and the sticky stuff on the refrigerator door gasket. They don't kill germs on contact -- that takes a few seconds of prolonged exposure -- but they work faster and better than sponges and brushes on hard to get to areas. Are you little concerned about what's growing in that spot between the porcelain water tank and base of your toilet? Life's too short to spend it stressing. A steam cleaner is the answer.
