Cleaning the oven is one of those household chores that is easy to postpone. Over time, grease splatters, baked-on food, oil, and sauce can build up on the oven walls and door, creating a sticky layer that becomes harder to remove with every use.
Fortunately, you don’t always need expensive specialty cleaners to tackle ordinary oven grime. A simple old-fashioned method using baking soda, water, and white vinegar can help loosen grease and make the oven much easier to clean.
The key is not to scrub harder. Instead, let the cleaning mixture sit long enough to soften the buildup first.
Why Oven Grease Becomes So Difficult to Remove
Every time you roast, bake, broil, or cook something that contains oil, tiny droplets can splatter inside the oven. At high temperatures, those droplets can become firmly attached to the oven’s interior surfaces.
Food particles can also fall onto the bottom of the oven. When the oven is used repeatedly, these particles may become carbonized and increasingly difficult to wipe away.
The longer the buildup remains, the more stubborn it becomes.
That’s why regular light cleaning is usually much easier than waiting until the oven is covered in thick layers of grease.
The Simple Ingredients You Need
For this traditional cleaning method, you only need a few inexpensive household supplies:
Baking soda
Water
White vinegar
A sponge or microfiber cloth
A small bowl
Rubber gloves
An old soft toothbrush or small cleaning brush for corners
You don’t need to use a large quantity of baking soda. The goal is to create a thick paste that can cling to dirty surfaces.
Step 1: Make Sure the Oven Is Completely Cool
Before cleaning, turn the oven off and allow it to cool completely.
This is especially important if you have recently cooked at a high temperature. Working inside a hot oven can cause burns and can also make cleaning products dry too quickly.
Once the oven has cooled, remove the racks and set them aside.
If there are loose crumbs or pieces of burnt food at the bottom, remove them first. You can use a dry cloth, paper towel, or soft brush to collect the debris.
Getting rid of loose particles first makes the deeper cleaning process much easier.
Step 2: Remove the Oven Racks
Take the racks out of the oven so you can clean them separately.
Place them in a bathtub, large basin, or sink if there is enough room. Cover them with warm water and add some ordinary dish soap.
Let them soak for a while, especially if they have greasy residue.
After soaking, use a non-abrasive sponge to clean them. Rinse them thoroughly and dry them before putting them back into the oven.
Avoid using extremely aggressive tools that could damage the rack’s finish.
Step 3: Make a Baking Soda Paste
Place about ½ cup of baking soda in a small bowl.
Add water gradually, mixing as you go.
You want a thick paste rather than a watery liquid. If it becomes too runny, add a little more baking soda. If it is too dry, add a few drops of water.
The finished mixture should be easy to spread and thick enough to stay on the oven walls.
Step 4: Apply the Paste to the Dirty Areas
Spread the baking soda paste over areas covered with grease and baked-on food.
Pay particular attention to:
The oven floor
The back wall
The side walls
Areas around the corners
Greasy sections near the door
You don’t need to cover every surface with a very thick layer.
Important: Avoid applying the mixture directly to heating elements, electrical components, gas openings, or other parts that the manufacturer says should remain dry.
If you’re unsure which parts can safely be cleaned with water-based products, check your oven’s instruction manual.
Step 5: Let the Baking Soda Work
This is the part that makes the method effective.
Instead of immediately scrubbing the oven, allow the baking soda paste to remain on the dirty surfaces for several hours.
For heavy buildup, leaving it overnight can give the paste more time to loosen the residue.
The baking soda helps work against greasy deposits and makes stubborn residue easier to remove mechanically.
The longer you allow the paste to work, the less effort you may need when wiping the oven later.
Step 6: Wipe Away the Grime
After the paste has had enough time to sit, put on your gloves and begin wiping the oven with a damp sponge or microfiber cloth.
Work in sections rather than trying to clean everything at once.
