Learning how to clean a countertop oven isn’t exactly anyone’s idea of a good time.
Most of us start with good intentions.
You wipe it down after the first few uses.
Maybe even the second.
Then life happens.
A little cheese drips onto the tray.
A few crumbs collect in the corners.
Some grease splatters onto the walls.
Before long, every time you open the door, you’re greeted by evidence of every pizza, cookie, chicken wing, and leftover you’ve cooked for the past month.
The good news is that cleaning a countertop oven is much easier than scrubbing a full-size oven.
And if you stay on top of it, you’ll spend more time cooking and less time wondering whether that smell is dinner or last month’s burnt cheese.
This guide will show you exactly how to clean a countertop oven, remove grease safely, and keep it looking and performing its best.
Short Answer
To clean a countertop oven:
- Unplug the oven and allow it to cool completely.
- Remove trays, racks, and crumb trays.
- Wash removable parts with warm soapy water.
- Wipe the interior with a damp cloth and mild cleaning solution.
- Remove grease buildup using baking soda paste or a gentle degreaser.
- Wipe the exterior clean.
- Dry everything thoroughly before reassembling.
Regular cleaning prevents odors, smoke, grease buildup, and cooking performance issues.
Why Regular Cleaning Matters
A dirty countertop oven isn’t just unattractive.
It can also cause:
- Unpleasant odors
- Excess smoke
- Uneven cooking
- Burnt food residue
- Reduced efficiency
- Shorter appliance lifespan
The cleaner your oven remains, the better it tends to perform.
What You’ll Need
Before you begin, gather:
- Soft cloths
- Microfiber towels
- Warm water
- Dish soap
- Soft sponge
- Baking soda
- Small bowl
- Soft-bristle brush or old toothbrush
Avoid abrasive scrubbers that may scratch surfaces or damage nonstick coatings.
Step 1: Unplug and Cool Completely
This may sound obvious, but it’s worth mentioning.
Never clean a countertop oven while it’s hot.
Always:
- Turn it off
- Unplug it
- Allow it to cool completely
Safety comes first.
Step 2: Remove All Removable Parts
Take out:
- Wire racks
- Baking trays
- Air fry baskets
- Crumb trays
- Pizza trays
Cleaning these separately makes the process much easier.
It’s also a good opportunity to inspect them for stubborn grease buildup.
Step 3: Wash the Racks and Trays
Fill your sink with:
- Warm water
- Dish soap
Allow greasy trays and racks to soak for 15 to 30 minutes.
After soaking:
- Scrub gently with a sponge
- Remove food residue
- Rinse thoroughly
- Allow to dry
For stubborn baked-on grease, sprinkle baking soda over the surface before scrubbing.
Step 4: Clean the Crumb Tray
If your countertop oven has a removable crumb tray, congratulations.
This is one of the easiest parts to clean.
Remove the tray and:
- Empty crumbs into the trash
- Wash with warm soapy water
- Dry completely
A neglected crumb tray is one of the most common causes of unpleasant odors and smoke.
Step 5: Wipe the Interior
Now it’s time to clean the inside of the oven.
Mix:
- Warm water
- A small amount of dish soap
Using a soft cloth:
- Wipe the walls
- Wipe the ceiling
- Wipe the floor of the oven
- Clean the inside of the door
Be careful around heating elements.
Most manufacturers recommend avoiding excessive moisture near electrical components.
Step 6: Remove Stubborn Grease
This is where many people get frustrated.
Fortunately, a simple baking soda paste often works surprisingly well.
Mix:
- 3 parts baking soda
- 1 part water
Apply the paste to greasy areas.
Allow it to sit for:
- 15 to 20 minutes
Then wipe away using a damp cloth.
This method is particularly useful if you’re trying to remove grease from a countertop oven without using harsh chemicals.

A mixture of warm water and mild dish soap usually works well.
For stubborn spots:

- Rinse with a clean damp cloth
Finish with a microfiber towel for a streak-free shine.
Step 8: Clean the Exterior
The outside deserves attention too.
Wipe:
- Control panel
- Door handle
- Top surface
- Side panels
A damp microfiber cloth is usually sufficient.
For stainless steel models, follow the manufacturer’s recommendations for cleaning products.
Step 9: Dry Everything Thoroughly
Before reassembling:
- Dry racks
- Dry trays
- Dry crumb tray
- Dry the interior
Moisture left behind can contribute to odors and unwanted residue.
Step 10: Reassemble the Oven
Once everything is dry:
- Replace racks
