How should I clean the ceramic glass cooktop on my Kenmore 790 range?

Before first use, apply the recommended CookTop Cleaning Creme to the ceramic surface and buff with a non-abrasive cloth or no-scratch cleaning pad. Avoid harsh chemicals like ammonia or oven cleaners, as they can etch or discolor the cooktop. Never let aluminum foil or utensils touch the ceramic cooktop while it is hot, as this will cause damage. (Page 2)
