It’s one of the most avoided chores in the kitchen: cleaning the oven. The task is synonymous with thick chemical gels, rubber gloves, and noxious fumes. Facing layers of black, baked-on grease, many of us feel we have no choice but to reach for the most powerful, caustic cleaner on the shelf.

But there is a better, safer way. You can achieve a sparkling, like-new oven using a few simple pantry staples. This method takes some soak time, but the result is a fume-free deep clean you can feel good about.

The Problem with Conventional Oven Cleaners

Many heavy-duty oven cleaners use sodium hydroxide (lye), a highly caustic alkali that dissolves baked-on grease but can cause severe skin and eye burns and irritate the respiratory tract if misused. See authoritative hazard profiles from NIOSH and MedlinePlus. For workplace and first-aid context, see OSHA sodium hydroxide data.

The Overnight Baking Soda Method: A Fume-Free Deep Clean

This approach uses a gentle alkaline paste to soften carbonized soils overnight so they wipe away in the morning.

Step-by-Step

1. Empty the oven: Remove racks and accessories from a cool oven.
2. Make a paste: Mix baking soda with water to a thick, spreadable paste (think frosting).
3. Coat the interior: Spread paste on the bottom, sides, and back. Avoid heating elements and gas inlets.
4. Let it rest overnight: Close the door and allow at least 12 hours.
5. Wipe out: Loosened paste will look brown—wipe with a damp cloth; use a non-scratch pad where needed.
6. Neutralize residue: Spray white vinegar; it will fizz with remaining baking soda. Wipe clean and dry.

Tip: Major brands also suggest simple soap/vinegar/baking-soda approaches for glass doors; see GE Appliances support.

How to Clean the Oven Racks

Lay racks on an old towel in a tub, sprinkle generously with baking soda, spritz with vinegar to fizz, then cover with hot water and soak several hours or overnight. Scrub, rinse, and dry.

What about the Self-Clean Cycle?

Self-clean cycles use extreme heat (often ~900 °F) to incinerate soils. While convenient, they can produce smoke/fumes from burnt residues and may stress components if used improperly. See summaries and expert cautions from Consumer Reports and coverage explaining potential risks to electronics and indoor air (Real Simple).

FAQ

Can I use this on the glass door? Yes—paste + dwell time, then wipe and vinegar-rinse.

Will this work on a very dirty oven? Yes, but you may need a plastic scraper after the soak, or repeat once for heavy, carbonized layers.

Why vinegar at the end? It reacts with leftover baking soda to lift the chalky residue and leaves a neutral surface (many home pros endorse this sequence—see Family Handyman or Martha Stewart).
