Clean a conventional oven by preparing the appliance using a combination of vinegar and baking soda and vigorously scrubbing the inside. Some conventional ovens have a self-cleaning option that turns the heat on high enough to completely disintegrate any food debris left inside.
A homeowner who wishes to clean a conventional oven efficiently must first remove all racks and other accessories inside the oven, and then make a baking soda paste. One cup of baking soda to 6 tablespoons of water offers the correct consistency. After spreading this paste all over the interior surfaces of the oven, leave it to rest for 12 hours. Once that time has passed, wipe off the dried paste with a damp dishcloth before preparing the vinegar. Spray the vinegar anywhere inside the oven where the baking soda residue remains caked on, and let the two products react with one another. After this reaction, the oven is ready to be wiped down with a damp cloth.
Avoid caking any baking soda on the heating elements inside the oven at any point during this cleaning process. Using a plastic spatula can offer greater results than a damp cloth if the oven is particularly caked with residue.
