When it comes to glass care and maintenance, GlassRenu is the authority. GlassRenu first introduced their line of glass restoration tools years ago, starting with the Contractor Grade Scratch Removal System. All GlassRenu products are tough on stains, debris, bird droppings, and other types of dirt and dust, leaving the glass looking almost brand new.
You do not need to buy separate solutions for other surfaces such as granite or marble because GlassRenu takes care of all your cleaning needs for smooth surfaces.
Mix a small amount of GlassRenu solution to water, as instructed, or apply it directly on hard stains.
