Ryan Zerbe, with the Maryland Department of Environmental Protection in Montgomery County, says not as much as you think.

FOX 5's Melanie Alnwick spoke with Zerbe who said a 12-ounce coffee mug is really all that's needed to protect your driveway or your section of walkway.

Zerbe demonstrated that 12 ounces of melt would cover a typical driveway -- about 20 feet by 10 feet -- or approximately 10 sidewalk squares which adds up to about 40 feet.

Zerbe says if you want to keep your area ice free:

- Shovel first and shovel early

- Be sensible -- less is more when it comes to ice melt

- After it melts -- sweep it up -- it can be reused
