That sounds like the popular “no-scrub oven” trick 😊 It really can make cleaning much easier when done safely.
Here are two effective methods people use:
🧼 Method 1: The Ammonia Fume Trick (For Oven Racks)
⚠️ Best done outdoors or in a very well-ventilated area.
What you need:
- Large heavy-duty trash bag
- ½–1 cup household ammonia
- Gloves
Steps:
- Place oven racks inside the trash bag.
- Pour ammonia into the bag (it doesn’t need to cover the racks — fumes do the work).
- Seal the bag tightly.
- Leave overnight.
- The next day, open carefully (avoid breathing fumes).
- Wipe racks clean and rinse thoroughly with warm soapy water.
❗ Never mix ammonia with bleach — it creates toxic gas.
🌿 Method 2: Baking Soda Paste (Safer for Inside Oven)
What you need:
- ½ cup baking soda
- A few tablespoons water
- Spray bottle with vinegar
Steps:
- Mix baking soda with enough water to form a thick paste.
- Spread inside the oven (avoid heating elements).
- Let sit 8–12 hours or overnight.
- Wipe out with a damp cloth.
- Spray vinegar on residue (it will foam), then wipe clean.
💡 Extra Tips
- Clean spills quickly before they harden.
- Avoid harsh metal scrubbers (they scratch enamel).
- Keep the door slightly open afterward to air dry.
