Baking soda (sodium bicarbonate) is one of the most effective, economical, and safe natural grease-cutters in the kitchen. Because grease is acidic, the mild alkalinity of baking soda neutralizes fatty acids, breaking them down into soluble compounds while providing gentle, non-abrasive scrubbing power.
To maximize its effectiveness on caked-on grease across various surfaces, you need to prepare and apply it correctly depending on the job.
The Master Preparation: Baking Soda Degreasing Paste
While dry baking soda works for quick sprinkles, the single most powerful way to prepare it for tough grease is as a concentrated paste.
Recipe
-
½ cup baking soda
-
2 to 3 tablespoons warm water (or dish soap for extra lifting power)
-
(Optional) 1 tablespoon hydrogen peroxide (for burnt-on grease or dark stains)
How to Prepare
Mix the ingredients in a small bowl until it forms a thick, spreadable consistency similar to toothpaste. If it’s too runny, add a little more baking soda; if too dry, add a few drops of water.
How and Where to Use It
1. Range Hoods & Exhaust Filters
-
How to apply: Remove the metal mesh filters. Coat them liberally with the baking soda paste mixed with a few squirts of dish soap. Submerge them in a sink filled with boiling hot water for 15 minutes. The grease will lift effortlessly off the aluminum or stainless steel without heavy scrubbing.
2. Stovetops & Glass Cooktops
-
How to apply: Spread the paste evenly over burnt grease rings around burners or on smooth glass tops. Cover the area with a warm, damp cloth for 15–20 minutes to keep the paste moist and active. Wipe away with a microfiber towel; the softened grease will lift right off without scratching the surface.
3. Oven Doors & Interior Walls
-
How to apply: Spread the paste over the glass door and baked-on interior walls (avoiding heating elements and gas vents). Let it sit overnight (8–12 hours). The paste will dry and break down the baked-on carbon and grease. The next morning, spray lightly with white vinegar—it will effervesce (fizz)—then wipe clean with a wet sponge.
4. Greasy Sheet Pans & Cast Iron Backs
-
How to apply: Sprinkle a thick layer of baking soda over the greasy pan, add a drop of dish soap, and pour hot water over it. Let it soak for 30 minutes before scrubbing with a soft pad.
Pro-Tips for Success
-
Heat is your best friend: Combining the paste with hot water or a warm damp towel speeds up the chemical reaction that breaks down hard fats.
-
Never use on delicate aluminum finishes long-term: While great for stainless steel, glass, enamel, and ceramic, leaving high-alkaline pastes on unsealed aluminum for extended periods can dull or discolor the metal.
