did it have to bekoshered - can i put food in a tin and use it that way f i didnt burn the grill ebfore
The process of koshering a grill is called Libun. This can he done on Pesach. Just let the grill heat up for a few minutes. That burns out any chametz, and you can use it.
Can an oven be koshered via self clean on pesach as well?
Can a microwave be koshered on pesach as well?
If so how?
if you can clean it good and use a solid double wrapping, it would be ok
