Clean the glass cook top with water and a soft sponge to remove as much loose food debris as possible. Leave water on any stubborn pieces of food to soften, which will help in its removal.
Wipe up any remaining water, then spread a circle of droplets of glass cook top cleaner around the area which has the baked-on grease. Use a plastic scrub pad to swirl the cleaner in a circular motion all over the grease stains. Push down on the scrubber to aid in the cleaning action.
Rinse the glass cook top with a sponge and clear water to see if the grease has been removed. If some grease remains, place a small amount of glass cook top cleaner directly on the grease spots and allow it to soak in for about five minutes.
Hold a razor blade scraper at a 45-degree angle and push down on the blade hard enough to get it beneath the caked-on grease, but not so hard that you scratch the glass itself.
Clean the cook top with glass cook top cleaner and a plastic scrubber. Rinse the cook top with cool water and use paper towels to dry the surface.
