Pool Stain Eraser for Concrete
GREAT WAY TO REMOVE STAINS AND SCUM LINES!Works like a pencil eraser to remove most types of stains without harsh chemicals and is made of a surface-safe polymer with a built-in mild abrasive that won't gouge or damage your pool surface. It can be attached to your telepole to reach stains anywhere in your pool. But it's not compatible with acrylic spa surfaces.
