Product review (5 stars): Easy to keep looking brand new.
We replaced an aging gas enameled cook top with this ceramic one (white).  It usually cleans very easily with just some 409.  Occasionally you need to use the cleaner / polisher supplied with the cook top to remove stubborn burnt on stuff close to the burners.  The burner covers are coated with some amazing space-age finish as well: a soapy plastic scrubber will clean off burnt on gunk and make them look brand new.

My only beef is the locked light which lights up when the gas on buzzer is enabled.  When locked, the unit spends 20+ hours a day with the light ON.  The light should really mean UNLOCKED.
