CLR Metal Clear is a mildly abrasive cleaner that polishes and shines stainless steel sinks, porcelain fixtures, granite counter tops and more without scratching or damaging surfaces. It is also perfect to remove tough, caked-on food stains from cookware bottoms and keeps your chrome or aluminum hubcaps and wheels looking like new. CLR Metal Clear can be used on chrome, porcelain, stainless steel, aluminum, granite, enamel, laminate counter tops and Corian. Always spot test in an inconspicuous area first.
