Dampen a paper towel with water. Squirt about 1 tbsp. cooktop cleaner on your soiled KitchenAid cooktop. Rub the cleaner all over the cooktop with the damp paper towel, paying particular attention to heavily soiled areas.
Use a cooktop scraper to scrape off any cooked-on food or grease. Wipe the scraper with a paper towel, and wash with mild dish detergent. Dispose of any soiled paper towels.
Dampen another paper towel and squirt 1 tsp. of cooktop cleaner on your cooktop. Polish the entire cooktop, dispose of the dirty paper towel and buff with a clean, dry paper towel.
