Selecting cookware
Copper bottom and aluminum pans
may leave a residue on the cooktop in
the form of metallic lines. This is
normal. These lines can be removed
using a non-abrasive ceramic cooktop
cleaner or a shielded scraper blade.
Be sure to clean the cooktop after
each use. Each time this residue is
allowed to melt it becomes harder to
remove and may mar the
appearance of the cooktop.
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
cooktop surface.
