How do I kasher my oven for Pesach?👀

How do I kasher my oven for Pesach?  Now, if you have a self-clean oven,   that's great. Just put on the self-clean  cycle. You could do a 3-hour or 4-hour   cycle. It doesn't have to be the longest  cycle. That will get it up to temperature,   and it will be kashered. But, if you used it with  chametz within 24 hours, technically speaking,   it will be kashered because it's libun gamur  (burning). However, it is recommended to not   use it for chametz beforehand for 24 hours,  even though you are doing libun gamur on it,   because there are still questions in terms of  the proper way to kasher even when you're using   a self-clean oven. So to avoid all problems,  it is best to not use it for 24 hours prior to   kashering. If you don't have the luxury of  waiting 24 hours, like you just moved into   an Airbnb and you need to kasher right away, you  can do the self-clean even if it might have been   used within 24 hours. If you have a regular oven,  now here it is imperative that you wait first 24   hours. You should clean it with a costic cleaner  like those off cleaners because otherwise the   libun doesn't necessarily burn out all the chametz  and therefore at least you'll use a costic which   will make it inedible. After you have it perfectly  clean, you turn it up to the highest temperature,   which is usually 550 or more and you let it burn  out for at least an hour at that temperature.   And this is what's known as a libul kal. Many  poskim in cases where a person can't do a libun   gamur on their oven, they accept this as well.  And then now your oven is kosher for Pesach.
