Rita: maybe this will help
This is a great guide
Here's what I do:
Here are a bunch of ideas! https://www.hometalk.com/search/all?filter=how%20to%20clean%20oven
My oven has a steam cleaner feature which doesn't clean as well as my high temperature self cleaning oven did. So if there is buildup the steam feature doesn't clean, I use Easy Off No Fume.
First off, use the self-cleaning setting if you have it. Remove anything sitting on top of the stove and take out the oven racks. Turn on self-clean, open a window and turn on a fan. Don't leave it unattended, but the oven will lock until it has completely cooled. At that time, wipe out the ashes with a damp paper towel.
If this isn't an option, set a glass pan of ammonia in your oven overnight. Warm the oven slightly and then turn it off before putting the ammonia in the oven. In the morning, wipe it out with a soapy rag.
Hi Rita: What I use is a paste of vinegar and cream of tartar (the dry stuff). Make a paste of vinegar and cream of tartar (use just a bit of vinegar at first as the cream of tartar sort of melts) and put it on the gunk. Maybe start out with 3 tablespoons of cream of tartar and a 1/2 teaspoon of vinegar. Add more of whatever to make a paste. It should stick to a vertical surface if it's thick enough. Let it sit for about 15 or 20 seconds and then scrape off with a plastic putty knife or one of those plastic scrubbies. You may have to do it a couple of times if the gunk is thick, but usually not. There is no smell and it is environmentally safe. A lot of people don't know, but on most stoves, the door comes off and the bottom of the oven comes off. You don't have to take the door off to get the oven floor out. Sometimes it's hard to get the door back on:) Also, the rack holders are removable:) This also works really good on pots, pans and cookie sheets with a burnt on mess. Good luck.
