I use neither one.
Cannot see the waste of energy and extra heat in the summertime, for self clean.. and I think Easy Off could be classified as a chemical weapon.! LOL I hate that stuff
... To clean the oven we pour a cup of water in the bottom, and bake for 30 minutes at 190 or so. I forget what the book specifies. But keep it under boiling point. It's in the owners manual of our range.
...This steam cleans the oven, and most stuff just wipes out.
....if your oven does not have a solid pan in the bottom, to put water in, just use a cup of water in a baking dish.
This method still requires a bit of elbow grease, but works well for us, as we are preventative, and try to clean up any messes before they accumulate.
