Easy steps for a spotless oven.
1/2 cup baking soda
3 tablespoons water
1/2 cup distilled white vinegar
Remove oven racks and clean with soap and a Heavy Duty Scrub Sponge.
Mix 1/2 cup of baking soda with 3 tablespoons of water in a bowl. Spread the paste with gloved hands on all non-heating surfaces and corners of your oven.
Leave for 12 hours (overnight is easiest).
Dampen a Non-Scratch Scrub Sponge to remove the paste. Spray remaining paste with distilled white vinegar until it foams. Use damp sponge to remove, adding vinegar and water as you go, until the oven is spotless.
