Difficult to clean, unless you don't care about streaks.  It is like a mirror, shows every spot, streak, smudge.  I am a good housekeeper & this stove top  requires too much of my time to get it clean.  I liked my old one much better!!!!!  (old one purchased 1995 GE Profile, was still in perfect condition, except 1 burner no longer worked & couldn't be replaced.
