Allow the glass cooktop to cool before beginning the cleaning process.
Fill a plastic container with warm water. Add three drops of dish soap and mix with a spoon. Dampen a clean sponge in the mixture.
Begin scrubbing the glass cooktop with the damp sponge in a circular motion. Start at the top of the cooktop and scrub while working your way downward.
Sprinkle baking soda on the sponge and scrub tough-to-remove burnt food off the glass with the baking soda and sponge. Apply white vinegar to a cloth and wipe grease off the glass cooktop.
Dampen a clean, lint-free cloth in cool water and rinse the cooktop clean by wiping with the cloth. Dry the stove top with a lint-free towel.
