Various soil levels require different cleaning methods:
Light to Moderate Soil: Apply cooktop cleaner with a non-abrasive pad, paper towel or clean cloth. Hand dishwashing detergent and water or a baking soda paste can also be used if cooktop is rinsed thoroughly and completely dried.
Heavy Soil, Metal Markings, Brown/Gray Stains from Hard Water: Gently scrub with cooktop cleaner using a clean cloth or paper towel. Reapply cleaner. Cover with damp paper towels to keep cleaner moist. Let stand for 30-45 minutes. Scrub to remove remaining stain. Do not use abrasive powders or pads since they may scratch the surface.
Burned On, Crusty Soils: Hold a razor blade scraper at 30 degree angle and very carefully scrape off soil. Clean remaining soil with cooktop cleaner.
If plastic, sugar or foods with a high sugar content melt onto a hot cooktop, remove immediately. (If not removed, permanent damage may occur.) Scrape from hot surface using a razor blade scraper held carefully with a potholder or use a wooden handled stainless steel spatula. Clean residue with cooktop cleaner when surface has cooled.
