How to Clean an Oven Rack With Ammonia

When you use your oven often, you need to clean it to remove baked-on food and debris. While many people put off cleaning their ovens, you need to clean it to keep it in good condition. Ammonia will remove built-up grease and scorched food from the oven racks, and does not smell as harsh as commercial oven cleaners.

Open the windows in your home to ventilate the room. Preheat your oven to 65.6 degrees C.

Bring a pot of water to a boil. Turn off the oven after it preheats.

Add ½ cup of ammonia to a heat safe bowl. Place the ammonia in the top rack of the oven.

Place the pot of boiling water on the bottom rack of the oven. Close the oven door and leave the ammonia and water to sit overnight.

Remove the ammonia and water the next day. Take the racks out of the oven.

Wash the oven racks in a sink full of warm, soapy water. Use an abrasive sponge to scrape away debris.

Place heavily soiled racks in garbage bags. Pour ½ cup of ammonia over the racks, tie the bag shut, then place the bag outside for two to three hours.

Remove the racks from the bags. Wash them in the sink and wipe dry with a washcloth.


Never use ammonia to clean a gas oven. Do not mix ammonia with other cleaning agents like bleach.
