To Protect Pavement

Look for: Potassium acetate, or corn and sugar-beet extracts

Why: Potassium acetate won't corrode paving (though it may make bare areas slick if overapplied). Plant-based extracts act as corrosion inhibitors to deicing chlorides.

Product picks: Potassium acetate–based liquid IceClear (about $30; montereylawngarden.com) and Bare Ground Solution (about $15; bareground.com), with corn extract, can prevent ice or be used later to melt it.
