Looking at new hobs. For various reasons only ceramic or old-fashioned electric hotplate will suit. But the instructions for ceramics seem...odd. Don't get it dirty, if it is dirty only clean with plain water and a soft cloth. Never let pans boil over. God forbid you should ever need to give it a good scrub with a cream-cleaner. (Apparently it will be ruined). Never use if the glass is chipped (ermm its glass, surely chips are inevitable.) Is this the ultimate triumph of looks over functionality? Can anyone reassure me their ceramic hob is not a total pain?
