Potassium and magnesium chlorides are frequently used as deicers under sidewalk sand and, although they contain chloride that may be toxic to plants in large quantities, these products, when applied properly, are less environmentally damaging than sodium or calcium chloride products. Potassium and magnesium chlorides are readily available, moderately priced, and easy to apply to sidewalks, walkways, and entrances. 

Potassium acetate, potassium chloride, and magnesium chloride are reliable choices for smaller areas such as bridge decks, sidewalks, walkways, and entrances. Potassium acetate is a biodegradable liquid deicer with good ice-melting capacity. It is frequen

Potassium acetate is a biodegradable liquid deicer with good ice-melting capacity. It is frequently used as a pre-wetting agent for sand and, though it is corrosive, a corrosion inhibitor is added.
