The 2-Ingredient Baking Paste That Melts Burned-On Oven Grease in Minutes
The Cleaning Science: Why This Combination Works
Baked-on oven grime isn’t regular grease; it is polymerized fat. When oil is heated repeatedly to high temperatures inside an oven, it undergoes a chemical reaction, cross-linking into a tough, plastic-like varnish that bonds tightly to the glass surface.
To break this bond without scratching the delicate glass, you need a combination of high alkalinity and mild, uniform abrasion:
- Baking Soda (Sodium Bicarbonate): This natural powder is mildly alkaline (pH around 8.1). Its basic nature helps break down and saponify the acidic fatty acids present in baked-on cooking grease, softening the hard varnish.
- Liquid Hydrogen Peroxide (or Water): Mixing baking soda with 3% hydrogen peroxide creates an effervescent, oxygenating reaction. The tiny bubbling action physically helps lift the loosened grime off the glass substrate, while acting as a gentle whitener for surrounding enamel stains.
- Zero Micro-Scratches: Unlike steel wool or harsh razor blades—which can create micro-fissures in tempered oven glass, eventually causing it to shatter under high heat—baking soda crystals dissolve slightly as they work, offering an abrasive texture that is completely safe for glass.
