Kashering Stovetops for Pesach

How do I kasher my stovetop for Pesach? Now  there are different types of stovetops. Some   people have a gas burner. With a gas stovetop,  the main thing to kasher is the stovetop grate.   The rest of it just needs to be covered, so you  just cover aluminum foil over the middle section   of the stovetop, and the stovetop grate you could  put into your oven. When you kasher your oven,   you could kasher that along with it, even if  your oven only gets to 550. For the stovetop,   that's no problem. All it needs is libun kal. The  550 would certainly qualify for it. You don't have   to kasher the burner part where the flames come  out. The flames anyway will burn up everything   there, and even if there would be something still  on there, nothing touches the food, so that's not   an issue. Then that's how you do a gas stovetop.  If you have an old-style electric burner where   the burner is exposed, it just gets red-hot, and  turning on that burner, once the metal gets red,   that'll be the libun gamur. That completely  kashers that. And again, the middle sections   of the stove you would put down aluminum foil in  case something falls there, it would be covered.   If you have the newer type of glass top stoves,  which can also don't kasher glass for Pesach,   so therefore you should cover it. How do  you cover it? They sell mats that you can   purchase that were meant to cover over the glass  tops, different materials, either fiberglass or   silicone. There are also discs you could buy.  There's something called induction discs,   also called diffuser discs, different names for  the different types. You put them on top of the   burner, and then you put your pot on top of that,  and that will act as your blech, so to speak. The   other areas of the stove that you won't be  using, just cover that with aluminum foil.
