Cleaning showers and baths is hard enough, and when you add granite cleaning and other natural-stone care to the task, it shouldnt make it more difficult. Ordinary, everyday shower and bath cleaners can damage your natural stone and lead to costly repair and replacement. Granite Gold Shower Cleaner is a streak-free formula that safely deep-cleans granite, marble, travertine and all other natural-stone and ceramic-shower walls and tub surrounds without damaging natural-stone surfaces. Regular use will help prevent mold, mildew, soap scum and hard-water deposits.
