If your oven smells smoky before dinner is even in it, the problem usually isn’t the appliance — it’s yesterday’s grease and food residue being heated all over again. A fresh spill is easy to wipe. The same spill after five or ten cooking cycles can turn into a hard, dark layer that takes far more effort to remove.
The good news is that you can clean an oven naturally in most cases, without reaching for a heavy-duty oven cleaner. For light to moderate buildup, baking soda, warm water, white vinegar and lemon will usually do the job. The important part is knowing where each ingredient belongs. Oven enamel, racks, door glass, gaskets, heating elements and controls aren’t the same surface, so one homemade mixture shouldn’t be used across the entire appliance.
At Now It’s Clean, this is how we approach professional oven cleaning in Toronto: identify the oven type, check the condition, protect sensitive components, then choose the least aggressive method that will actually remove the buildup. This guide applies the same basic approach to a safe DIY clean.
Can You Really Clean an Oven Naturally?
Yes – if the buildup is mainly grease, food splatter and ordinary baked-on residue, and the oven manufacturer allows manual cleaning on those surfaces. Baking soda can help soften stubborn residue, while white vinegar can remove leftover baking-soda film. Lemon is more useful for light soil and odour than thick, carbonized grease.
The manufacturer’s instructions still come first. GE Appliances Canada explains that oven cleaning methods and precautions can vary by appliance in its oven-care guidance. Samsung Canada also provides cleaning guidance for its ovens, including different instructions for Self Clean, Steam Clean/Hybrid Clean and manual cleaning. These differences matter because the oven type, model and surface materials determine which cleaning methods are appropriate. If the manufacturer’s instructions conflict with a general cleaning tip, always follow the manual.
Before You Start: A Safe Oven-Cleaning Check
Let the Appliance Cool Completely
Turn the oven off and wait until the cavity, racks and door are cool enough to touch. Cleaning a hot oven raises the risk of burns and dries out a homemade paste before it has time to work.
Check the Oven Type and Finish
Find out whether the oven is manual-clean, steam-clean, self-cleaning or fitted with a specialty liner. Check whether the heating element is exposed, whether the racks can be soaked and whether the door glass has a coating that limits abrasive cleaning.
Keep Cleaner Away From Sensitive Components
Do not spread wet paste over heating elements, gas ports, ignition components, sensors, fans, vents or electrical openings. Avoid saturating or pulling the door gasket. Those parts can require a different cleaning method – or appliance service rather than cleaning.
Ventilate and Keep Children and Pets Away
Open a window or use the range hood where practical, and keep children and pets away from the open oven and cleaning materials. Health Canada’s household chemical safety guidance recommends good ventilation when using household chemical products and advises keeping these products out of the sight and reach of children and pets. It also warns against mixing household chemical products, as some mixtures can produce harmful gases.
What Natural Ingredients Work Best?
Baking Soda for Baked-On Residue
Baking soda is mildly alkaline and slightly abrasive. With a little water, it forms a paste that can cling to greasy residue without running off the surface. Its main benefit is giving the paste time to soften and lift residue without aggressive scrubbing.
White Vinegar for Removing Baking-Soda Residue
White vinegar is acidic. On compatible surfaces, a small amount can help remove the white baking-soda film left after wiping. We do not recommend soaking the oven in vinegar or assuming an acidic cleaner is suitable for every coating.
Lemon for Light Buildup and Odour
Lemon is useful when the oven needs freshening or has light buildup. It is not a substitute for removing thick grease, and because it is acidic, it should be kept away from surfaces the manufacturer says should avoid acids.
Warm Water for Softening and Rinsing
Warm water helps soften loose food residue, keeps a baking-soda paste workable and removes cleaning residue at the end. The key is control: use a damp cloth rather than flooding the oven cavity.
What You Need
- Baking soda
- Warm water
- White vinegar, if your oven instructions allow it
- Lemon, optional
- A bowl and spoon
- Microfibre cloths
- A non-abrasive sponge
- A soft nylon brush
- A plastic scraper for compatible surfaces
- Rubber gloves
- Old towels for the floor
Avoid steel wool, knives and aggressive scouring pads unless the manufacturer explicitly permits them. A tool that removes grease quickly can also scratch or damage the oven’s finish.
How to Clean an Oven Naturally: Step by Step
Step 1: Remove Racks and Dry Debris
Remove removable racks and accessories if the manual permits. Wipe or vacuum loose crumbs, burnt food and dry debris from the cool oven. Removing them first makes the rest of the cleaning easier.
Step 2: Make a Baking-Soda Paste
Place the baking soda in a bowl and gradually add water until the mixture is thick enough to cling to the surface. There is no need for a rigid ratio; aim for a spreadable paste that does not run.
Step 3: Treat the Dirty Areas, Not the Entire Appliance
Spread a thin layer over compatible greasy or baked-on areas. Keep the paste away from heating elements, electrical components, vents and the door gasket unless the manufacturer specifically says they can be cleaned this way. The right approach is targeted cleaning rather than covering every part of the appliance.
Step 4: Let the Paste Soften the Buildup
Give the paste enough time to soften the buildup. For heavier residue, several hours or overnight may be needed. The exact cleaning time can vary with the condition of the oven, so follow any time limits or cleaning instructions in the appliance manual.
Step 5: Wipe and Lift Rather Than Scrape Aggressively
Use a damp microfibre cloth or non-abrasive sponge to remove the paste and softened residue. For stubborn spots, hold a damp cloth against the area first to help soften them. If a scraper is appropriate for the surface, use a plastic scraper at a low angle rather than digging with metal.
Step 6: Use Vinegar Only Where It Helps
If the surface allows vinegar, use a small amount on a cloth or as a light mist to remove remaining baking-soda film. The fizz is simply the reaction between the two ingredients, not a sign that they become a stronger cleaner. That is why we prefer using them in sequence instead of premixing them.
Step 7: Rinse and Dry
Wipe again with a clean damp cloth until the residue is gone, then dry the surface. Make sure no baking-soda paste or cleaning residue remains before the oven is used again.
Step 8: Reassemble Only When Everything Is Dry
Return the racks and accessories after the cavity is dry. Make sure no paste, cloth or loose debris remains inside before cooking.
How to Clean Oven Racks and Door Glass
Oven racks can be cleaned separately with warm water and a small amount of dish soap if the manufacturer allows soaking. Use a non-abrasive pad or soft brush to remove loosened residue, then rinse and dry the racks. Check the manual before leaving racks inside during a self-clean cycle, as rack materials and finishes can react differently to high heat.
For the door glass, start with a cool door and wipe it with warm water and a soft cloth. On compatible glass, a small amount of baking-soda paste can help loosen baked-on splatter. Keep excess moisture away from the gasket and door openings. If grease is trapped between the panes, check the manual before attempting to remove or dismantle the door, as the cleaning procedure varies by model.
What We Do Differently During Professional Oven Cleaning
The difference between a DIY clean and professional oven cleaning is not a secret chemical. It is the process. Our oven-cleaning service considers the oven type, level of buildup and areas that need different treatment.
- We assess the oven before cleaning and identify any concerns that may need attention beyond cleaning.
- We remove racks and other removable parts so they can be cleaned separately.
- We use products and methods suited to the oven and the surfaces being cleaned.
- We adjust the approach for different oven types rather than treating every appliance the same way.
- When included in the booked service, we can also clean areas such as the door glass, stovetop or range, range hood and other kitchen appliances.
- We finish by removing cleaning residue and checking the work before completing the service.
If your oven has an electrical fault, gas problem, damaged control, cracked component or another issue that requires repair, cleaning is not a substitute for appliance service. An appliance professional should handle these problems.
Where Oven Cleaning Fits Into a Home Cleaning Service
Oven cleaning is usually a detail or deep-cleaning task rather than part of basic home maintenance. Regular cleaning typically focuses on accessible kitchen surfaces such as countertops, sinks, cabinet fronts and appliance exteriors, while cleaning inside the oven is often handled as a separate add-on or deeper-cleaning task.
If the rest of the kitchen needs deeper attention – such as cabinet buildup, backsplash grease, range hood residue, appliance exteriors and hard-to-reach areas – a broader home cleaning service may make more sense than cleaning the oven alone.

How Often Should You Deep Clean an Oven?
There is no single schedule that fits every home. Someone who roasts frequently, cooks fatty foods or has regular spillovers will need to clean more often than someone who uses the oven occasionally.
Instead of watching a calendar, watch the appliance. Clean when you see grease film, baked-on food, persistent odour or smoke caused by residue. Wipe new spills after the oven cools. Regular light maintenance is easier than waiting until several months of buildup have hardened into one layer.
When DIY Is No Longer the Best Option
DIY makes sense when the buildup is manageable, the surfaces are compatible and there is enough time to let a gentle method work. Professional cleaning becomes more practical when the residue is heavily carbonized, the racks are deeply soiled, you are concerned about the finish, or the oven is part of a larger kitchen that needs a deeper clean.
If you would rather leave the detailed work to a professional, Now It’s Clean can clean gas, electric and double ovens, along with stovetops, ranges and other kitchen appliances. The team can assess the oven’s type and condition to determine the scope of the cleaning.
Ready to Get the Oven Off Your To-Do List?
A good DIY clean should leave the oven cleaner without damaging its finish or sensitive components. If baking soda and patience are enough, use them. If the buildup has moved beyond a reasonable DIY clean, professional oven cleaning can take care of the detailed work.

Frequently Asked Questions
What Is the Best Natural Ingredient for Cleaning an Oven?
Baking soda is a good starting point for compatible oven surfaces. Mixed with water, it forms a paste that can cling to baked-on residue and help loosen grease without aggressive scrubbing. Always check the oven manual before using it.
Can I Clean My Oven With Baking Soda and Vinegar?
Yes, on compatible surfaces. Use baking soda first to soften the residue, then use a small amount of vinegar to help remove the remaining baking-soda film. Using them separately is more useful than premixing them because they react and neutralize each other.
Can I Use Vinegar on Oven Glass?
Vinegar may be suitable for some oven glass, but surfaces and coatings vary by model. Use a soft cloth, avoid abrasive materials and check the appliance instructions before using vinegar or other acidic cleaners.
Can I Put Baking Soda on the Heating Element?
It is better to keep baking soda and other cleaning products away from heating elements unless the manufacturer specifically says they can be cleaned that way. Heating elements and other internal components may require different care.
Is the Self-Cleaning Function Enough to Clean an Oven?
Not always, a self-cleaning cycle is designed to handle certain types of oven residue, but the exact process and limitations vary by appliance. Check the manual to see what the self-clean function is designed to clean and which parts should be removed first.
How Long Should Baking Soda Sit in an Oven?
The time depends on how much buildup is present. Light residue may loosen after a shorter period, while heavier buildup may need several hours or overnight. Follow any time limits or cleaning instructions provided by the oven manufacturer.
How Do I Clean a Very Dirty Oven?
Start by removing loose debris, then apply a baking-soda paste to compatible areas and allow it time to soften the buildup. Wipe away the residue with a damp, non-abrasive cloth or sponge. Heavily carbonized buildup may require professional cleaning.
How Do I Clean Grease Between the Oven Door Glass?
Do not dismantle the oven door without checking the appliance manual first. Door construction varies by model, and some doors have specific procedures for accessing the glass. If the manual does not provide a suitable cleaning method, professional or appliance service may be more appropriate.
Does Regular Maid Cleaning Include the Inside of the Oven?
Not automatically. Interior oven cleaning is usually a detailed appliance task and should be confirmed as part of the booked service. Regular home cleaning is generally focused on maintaining accessible kitchen surfaces and appliance exteriors.
Are Now It’s Clean Cleaners Insured and WSIB-Covered?
Yes, all Now It’s Clean technicians are fully insured, bonded, background-checked, and WSIB-covered. We also carry $2 million in general liability coverage. Current documentation can be requested from the office when formal proof is required.
What Happens If I Am Not Satisfied With the Oven Cleaning?
We stand behind a 100% satisfaction guarantee. If something within the agreed cleaning scope is missed, contact the company promptly so we can return to make it right.
