📋 Step-by-Step Guide (6 Steps)
Clear the Oven Interior
Remove all oven racks, baking sheets, thermometers, and foil liners from inside the oven cavity. Set the empty racks into a sink or on a protected countertop for separate washing.
- • Empty oven cavity with bare floor, walls, and exposed heating elements.
- • Racks fully removed and resting outside the oven.
- • Leaving oven thermometers or pizza stones inside.
- • Scratching the oven enamel while pulling racks at an angle.
Mix the Degreasing Paste
Combine 1/2 cup of baking soda, 1 tablespoon of liquid dish soap, and enough water (about 2-3 tablespoons) to form a spreadable paste with the consistency of pancake batter. Stir thoroughly in a small bowl.
- • Thick, smooth, spreadable white paste with no dry powdery pockets.
- • Mixture clings to the spatula without running off like liquid.
- • Adding too much water, creating a runny liquid that pools on the floor.
- • Leaving baking soda clumps unmixed.
Apply Paste to Stained Surfaces
Using a spatula or gloved hands, coat the oven walls, bottom cavity, and glass door with a uniform layer of paste. Avoid direct contact with electric heating elements, gas burner tubes, or fan openings.
- • Interior enamel and glass door visibly covered with a white paste coating.
- • Heating elements and gas nozzles completely bare and clean.
- • Smearing paste directly onto exposed heating coils.
- • Applying too thin a layer over heavily charred hotspots.
Steam Loosen with Hot Vinegar Water
Fill an oven-safe dish halfway with equal parts water and white vinegar. Place the dish on the center floor, close the oven door, and turn the oven to 250°F (120°C) for 20 minutes to create grease-loosening steam.
- • Oven door closed with condensation forming on interior glass.
- • Baking dish bubbling gently inside the oven.
- • Setting the temperature too high and burning the paste.
- • Opening the door repeatedly and letting steam escape.
Scrub and Wipe Softened Residue
Once warm and safe to touch, remove the water dish with mitts. Use a non-scratch scouring pad to gently lift softened carbon, then spray remaining residue with vinegar and wipe clear with microfiber cloths.
- • Brown residue lifting easily onto pad and cloths.
- • Glossy enamel and clear glass visible under wiping strokes.
- • Using steel wool that scratches porcelain enamel.
- • Using a dry cloth which smears the emulsified grease.
Final Buff and Reassembly
Wipe down all interior surfaces with a clean, damp microfiber cloth to remove all trace residue, then buff dry with a second cloth. Reinstall the clean racks into their side grooves.
- • Sparkling, streak-free interior surfaces and transparent door glass.
- • Racks slotted horizontally and securely into wall tracks.
- • Leaving residual baking soda that creates white powder when the oven is next used.
- • Inserting racks upside down or misaligned.
