Can someone explain how to clean an oven like I'm 5?

Hey everyone! So, my chronic pain is a bit better now, and I finally want to start tidying up my house again. The thing is, I’ve always found cleaning the oven pretty intimidating honestly, I’ve never even tried. My parents kind of assumed I’d pick things up by osmosis, but that didn’t really happen.

If someone could break down how to clean an oven as simply as explaining it to a 5-year-old, I’d really appreciate it! Tips, product suggestions, and the best tools to make it easier would be awesome too.

Thanks a lot
