Kashering an Oven Rack for Passover
Question
Hello Rabbi!
How should one kasher the oven rack for Passover?
Assuming that during the rest of the year there was leavened food on it on top of baking paper (though it may have leaked onto the rack itself), and on Passover it will be used only as a base for a disposable pan?
(I saw answers only for cases where the use during the rest of the year and on Passover is the same kind of use.)
Answer
Clean it thoroughly with a strong cleaning agent. After that, heat it in the oven at maximum temperature together with the oven itself. If you are placing a disposable pan on it, then in principle there is no problem, but the custom is to kasher it.
