Is it ok to clean DO with handle?

I do not have an electrolysis tank so I am going to do my first cleanup using the self cleaning oven method as shown by The Culinary Fanatic on youtube. Will the handle on my DO be ok going through the oven cleaning method?

No, it will likely not. Easy Off HD in a trash bag would be your better option.
