Sleep-It-Off Oven Cleaner
Ingredients: salt, baking soda, water, a shaker (I used an old Parmesan cheese shaker), and a spray bottle with water and a couple tablespoons of Dr. Bronner's or dishwashing soap (like Dawn).
Mix ¼ cup salt with ¾ cup baking soda. Fill the shaker.
Spray the oven with soap and water spray. Shake the salt-soda mixture on. Spray again with water until the mixture is slightly damp and pasty. For the side walls, make a thick paste and sponge it on.
Leave it overnight. In the morning, get a putty knife/scraper, and scrape off the goop and pile it onto an old newspaper. Use a scotch-brite sponge to work off any tough spots. Wipe down with a soap and water spray. Rinse.
