Clean and shield your glass surfaces making them easier to clean next time, when used per label instructions, with Mr. Clean Professional Glass and Multi Surface Cleaner. Scotchgard technology makes cleaning faster and easier by applying a transparent shield to glass and silica-based surfaces, but is suitable for use on a wide range of hard surfaces. The Scotchgard Protector is an invisible barrier between the surface and soils that makes it more difficult for soils to adhere, making cleaning easier after repeated use.
