It removes almost any hard to remove grease or oil, on most surfaces. Don't use on wood, finished surfaces, or surfaces/walls that have been done in water based paints. Great in kitchens, restaurants, industrial offices where all types of oils and greases have affected the surfaces. Great for schools, since there is an invisible protective film, that leaves surfaces shiny and smooth, also protects from marks that can be made, and sub-sequentially, will make future cleaning easier.
