I've always had ceramic hobs, now on my third in 26 years! I use hob brite and sometimes I wipe over with vinegar to bring up a nice shine. I also have an old style razor blade which has one sharp side the other has a metal plate to hang onto which I use to remove any burnt on food. Lakeland also has a tool that does this, they also have little sponge tools that can get right in and around the controls as they can get quite grubby. (you can also get those from Kleeneze)
