Question
Is it mandatory to kasher the grates, or is it sufficient according to the law to clean and cover them with aluminum foil, and does one transgress a prohibition if they do not kasher, God forbid?
Answer
Shalom Rav
According to the law, it is permissible to clean the grates and cover them with thick aluminum foil that will not tear when placing and removing pots.
There is a benefit in libun (not in kashering) for certain cases where a large amount of water spills under the pot. However, it is not mandatory.
