A toaster oven earns its counter space. It reheats pizza, crisps bagels, and roasts a quick tray of vegetables, and all of that action leaves behind grease, crumbs, and the odd melted-on bit of cheese.
Once the inside looks grimy or you catch a burnt smell every time you switch it on, it is due for a clean. A toaster oven is a hybrid appliance, so you cannot treat it like a pop-up toaster or scrub it like a full-size oven.
Below is a simple, step-by-step routine to get yours spotless again, plus a heavy-duty method for baked-on grease and tips to keep it that way.
Key Takeaways
- Safety first: Always unplug the toaster oven and let it cool completely before cleaning to avoid burns or electric shock.
- Weekly upkeep: Empty the crumb tray, then wash the tray and rack by hand in hot, soapy water to protect any non-stick coating.
- Baked-on grease: Coat the interior with a baking soda and water paste, leave it overnight, then spray with vinegar and wipe it clean.
- Heating elements: Never use cleanser or foil near the elements; wipe them only with a soft, damp cloth once the oven is fully cool.
How Often Should You Clean a Toaster Oven?
To prevent fire hazards and bad smells, you should brush out crumbs after every single use. It takes five seconds, but it saves you a headache later.
For a general wipe-down, aim for once a week (or every 5-7 uses).
We recommend a deep clean once a month. This involves scrubbing the racks and removing that stubborn, baked-on food residue that accumulates over time. According to Breville’s official care guide, the brand recommends a lighter clean every 7 days, with a deeper clean added only as needed rather than on a fixed monthly schedule. Per that same Breville guide, the deep-clean routine breaks down into 6 steps, from an initial safety check through the heating elements.
How to Clean a Toaster Oven
For your standard weekly refresh, follow this simple routine. If you stay consistent with this method, you won’t have to spend hours scrubbing later.
- Time: 30 minutes.
- Difficulty: Easy.
What You’ll Need
- Sink or basin.
- Dish soap.
- Vacuum cleaner (handheld attachment).
- Bar Keeper’s Friend or baking soda.
- Microfiber cloths.
- Non-abrasive sponge.
1. Unplug and Cool Down
Toaster ovens are electric appliances, so safety is priority number one. Unplug the unit and ensure it is completely cool to the touch before you start. Cleaning a hot oven is a recipe for burns and cracked glass.
2. Disassemble the Parts
Remove the metal rack, the broiling pan, and the slide-out crumb tray. It is much easier to scrub these items in the sink than while they are inside the cramped oven.
3. Soak the Removable Parts
Fill your sink with hot water and a squirt of grease-cutting dish soap. Submerge the rack, pan, and crumb tray. Let them soak for 15 to 20 minutes to loosen up charred food.
4. Scrub and Rinse
After soaking, scrub the parts just like you wash dishes. A standard sponge or microfiber cloth works well here. For stubborn spots on the metal rack, you can use a bit of Bar Keeper’s Friend. Rinse well and set them aside to dry. If your rack or pan has a non-stick coating, wash it by hand rather than in the dishwasher. Breville recommends hand-washing removable parts to help them last longer, rather than running them through the dishwasher’s heat and detergent.
5. Remove Loose Crumbs
While the parts are drying, tackle the interior. Move the toaster oven near a trash can and gently shake it or tilt it to dislodge crumbs.
For the most effective clean, use the hose attachment of your vacuum cleaner to suck up debris from the corners and crevices.
6. Wipe the Interior
Dampen a microfiber cloth (do not soak it) with water and a little baking soda. Gently wipe down the interior walls and the ceiling of the oven.
Warning: Be extremely careful around the heating elements. These are fragile, and manufacturer guidance warns that cleanser or scrubbing can damage the metal surface, so wipe them only with a soft, damp cloth once the oven is fully cool (1).
Expert Advice
While Bar Keeper’s Friend is great for the metal racks, stick to baking soda or plain dish soap for the interior walls to avoid harsh chemical fumes the next time you cook.
7. Rinse and Dry
Wipe the interior again with a clean, damp cloth to remove any soapy residue or baking soda grit.
8. Reassemble
Once the interior and all removable parts are 100% dry, slide everything back into place. Do not plug the appliance back in until you are sure it is dry.
How to Clean Toaster Oven Glass
The glass door is usually the first thing to get dirty. Grease splatters can bake onto the glass, making it look brown and hazy.
- Time: 10 minutes.
- Difficulty: Easy.
What You’ll Need
- Distilled white vinegar.
- Water.
- Lemon juice.
- Spray bottle.
- Microfiber cloths.
1. Mix Your Cleaner
In a spray bottle, combine two parts water, one part white vinegar, and a tablespoon of lemon juice. The lemon helps cut grease and leaves a fresh scent.
2. Apply to the Glass
Open the oven door so it lays flat. Spray the solution onto the glass and let it sit for five minutes.
If your door has vents where liquid could drip into the glass layers, spray your cloth instead of the door directly.
3. Wipe Clean
Use a microfiber cloth to wipe away the grease. If you want a streak-free finish, you can buff it dry with a clean coffee filter or a dry cloth.
How to Get Baked-On Grease Out of a Toaster Oven
If you haven’t cleaned your toaster oven in months (we won’t judge), you likely have brown, baked-on grease stains. To fix this, we need the heavy-duty baking soda paste method.
- Time: 12 to 24 hours (soaking time).
- Difficulty: Intermediate.
What You’ll Need
- Baking soda.
- Water.
- Small bowl.
- Old toothbrush.
- Cloths or sponge.
- Spray bottle with white vinegar.
1. Create a Paste
Mix about ½ cup of baking soda with a few tablespoons of water. You want a consistency similar to toothpaste, thick enough to stick, but spreadable.
2. Apply the Paste
Remove the racks and tray. Spread the paste over the greasy areas inside the oven using a cloth or an old toothbrush. Focus on the corners and the ceiling.
Note: Avoid the heating elements. Getting paste on them can cause smoking or damage.
3. Let it Sit
This is the secret step. Close the door and let the paste sit for at least 12 hours, or overnight. This gives the baking soda time to break down the carbonized grease without you having to scrub for hours.
4. The Vinegar Trick
After the paste has hardened, spray the interior lightly with vinegar. It will fizz and bubble upon contact with the baking soda. This reaction helps lift the grime off the surface.
5. Scrub and Wipe
Use a damp sponge and plenty of elbow grease to scrub away the paste. The gunk should come off with it. You may need to rinse your sponge frequently.
6. Final Rinse
Wipe the entire interior with a clean, damp cloth to ensure no baking soda residue remains. Leave the door open to air dry completely.
How Does a Self-Cleaning Toaster Oven Work?
A self-cleaning toaster oven runs extreme heat or steam to turn food residue into ash that wipes away once the cycle finishes, similar to a full-sized self-cleaning oven. If all this scrubbing sounds exhausting, that hands-off option might be worth considering.
While convenient, these cycles use a lot of electricity and can take hours. Plus, they can get the exterior of the unit very hot. If you have a self-cleaning model, ensure you pull it away from walls and cabinets before running the cycle.
How to Keep a Toaster Oven Clean
Cleaning a toaster oven is fairly straightforward, but preventing the mess is even better. Use these tips to keep your appliance fresh:
- Brush out crumbs daily: Make it a habit to dump the crumb tray after you make your morning toast. This prevents old crumbs from catching fire or smoking.
- Cover your food: When reheating leftovers that might splatter (like pizza or wings), loosely cover them if your manual allows it, or use a covered baking dish.
- Skip foil on the crumb tray: It is tempting to line the crumb tray with aluminum foil to catch grease, but according to product manuals collected across the toaster oven market, at least 4 manufacturers, including Hamilton Beach, Cuisinart, Black and Decker, and KitchenAid, warn against it by name. Foil is a common culprit behind toaster oven fires, since loose foil touching the tray, walls, or heating elements can overheat, and trapped grease underneath it can catch fire. Per the same manufacturer guidance, 2 manufacturers, Black and Decker and KitchenAid, extend the warning to any foil contact with the walls or heating elements, not just the tray. The stakes are bigger than a scorched tray: from 2020 to 2024, an estimated 48 percent of home structure fires involved kitchen and cooking equipment, and unattended equipment was a factor in 25 percent of reported home cooking fires (2). Lining the tray can also void your warranty, so check your manual and leave the tray bare.

Enjoy Your Sparkling Kitchen
A clean toaster oven is more than a nicer view on the counter. Clear out the grease and crumbs and it heats faster, cooks more evenly, and stops throwing that scorched smell every time you switch it on.
The routine that keeps it there is small. Empty the crumb tray after your morning toast, hand-wash the rack and tray once a week, and save the overnight baking soda paste for the baked-on grease that sneaks up on you. Skip the foil, keep the heating elements dry, and the whole job stays a quick wipe instead of an hour of scrubbing.
With that sorted, your oven is ready for the next round of bagels, leftover pizza, or a properly melted cheese sandwich.
