Wetted with a 32% calcium chloride solution, rock salt immediately digs in and holds a close pattern on winter roads even when temperatures drop down to 0F (-18C).Wetted salt reduces the need for frequently repeated applications, decreasing material use by as much as 40%. Wetted abrasives: spray calcium chloride solution on abrasives to help them embed quickly in ice and snow, save applications, material, manpower and equipment costs.
