recipe for an oven cleaner using baking soda
I mix a cup of baking soda with 1/3 cup water and spread it on the oven fairly thick with a rubber spatula or a damp cloth. I let it set all night or all day if I am going to be gone from the house working etc. Then I spray /spritz it with white vinegar and let it bubble up. I wipe it off and repeat as necessary. It helps not to let the oven crust build up too long, esp. if you use your oven often. Hope this helps.
