Spread ice melt thinly: it needs only enough to start a brine, and extra salt just washes into the soil and the water. Clear the snow first, and spread before a storm if you can, since that stops the ice bonding to the pavement. Rock salt (sodium chloride) stops working somewhere around 15°F, and calcium chloride keeps working to about −25°F. These are typical rates for a home; where the label gives a rate, use it.

Before you buy: round up to whole packs, check the size printed on the label, and add a little spare. Your supplier has the final say.

20 treatments	120 lb	6	3	3

A three-car driveway: how many bags to keep in

A 24 × 50 ft driveway is 1,200 sq ft, so even a light frost takes 3.6 lb and a normal treatment 6 lb. One 40 lb bag covers about 6 normal treatments; 12 treatments take 2 bags, and 20 take 3.

Bags of ice melt draw in water and set hard, so store them off the floor in a dry garage or a lidded bin. On a driveway this wide, treat the lanes you drive and the walk to the door, and leave the rest until the plow or the shovel has done its work.
