Easy steps for a spotless oven.
1/2 cup baking soda
3 tablespoons water
1/2 cup distilled white vinegar
Mix ½ 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 Microfiber Kitchen Cloth to remove the paste. Spray remaining paste with distilled white vinegar until it foams. Use damp cloth to remove, adding vinegar and water as you go until the oven is spotless.
