We recently bought our first ceramic cooktop range and a sample bottle was included. I wasn't sure the product was worth it until after I put the first small scratch on the cooktop and the creme made it invisible. Also is wonderful for the spills that bake on the hot surfaces! I have found it is best to wait until the stovetop completely cools and then use the creme as directed. You will be amazed how the creme brings the cooktop back to a new apperance. I will never let myself run out of the creme, because I cook everyday and spills and messes are the norm for our stovetop. Thank you for such a wonderful product!
