Surface preparation is the critical first step in achieving a beautiful, long-lasting wood finish. Olympic Premium Deck Cleaner is a unique, premium quality product that penetrates deep to remove dirt and mildew stains.
On the advice of my sister I used it on my tile floors in kitchen and baths as per directions (for use on decks.) It did a marvelous cleaning job and a better shine. Will use regularly and the grout will be in shape.
