How can I effectively clean a glass cooktop that has burnt-on residue?

To effectively clean a glass cooktop with burnt-on residue, start by sprinkling baking soda over the affected areas. Then, spray white vinegar over the baking soda and let it sit for 15 minutes. Scrub the cooktop with a non-abrasive sponge or cloth in a circular motion. Finally, wipe the cooktop clean with a damp cloth.
