Can a typical outdoor gas grill be Kashered for Pesach? If so, how?


Yes, through Libun Gamur:

Run a fire in it for at least an hour (in the highest temperature setting) with the top down.

If you don’t replace the grates, then they need to be kashered by heating it with a blowtorch until it glows, or by sandwiching it between burning charcoal for an hour.
