Ammonia provides an easy way to clean an electric oven. Warm the oven to 150 degrees, then turn off the heat. Place a pan of boiling water on the bottom shelf and 1/2 cup of ammonia on the top shelf. Leave overnight. Wipe clean using the ammonia and dishwashing liquid.
To clean grime off the broiler pan, apply a mixture of 1 cup of apple cider vinegar and 2 tablespoons of sugar to the pan while it is still hot. Leave the mixture for one hour, then wipe clean. Keep the inside of the oven clean by wiping it down with white vinegar once a week.
