Can solid calcium chloride that has caked be made usable again?

When calcium chloride is stored in a manner that allows contact with humid air, the product is likely to become caked. If lightly caked, the product may be broken up into usable form by knocking the closed package against a hard surface, similar to breaking up a bag of ice purchased from a convenience store before adding to a cooler. In other cases, the caked product may be too hard for this approach to be effective. Use of forceful hammering is not likely to be effective and is not recommended, as flying chips of product could be a hazard, particularly to the eyes. Caked product that cannot be broken up into usable form may be disposed of according to the guidance on the product label.
