the cooking time.

– Sometimes what appear to be
scratches are not. Metallic lines such
as those left by copper or aluminum
pans can be removed using a
non-abrasive ceramic cooktop
cleaner. Let the cooktop cool before
cleaning.
– Cast iron, glass or stoneware should
not be used because they have poor
heat transfer and may scratch the
surface.
