Remove the racks, coat the inside with a baking soda and water paste, and leave it overnight. Next day, wipe it out, spray with vinegar where paste remains, and wipe again. Soak the racks in hot water with dish soap. Budget about 30 minutes of work spread over two days.
The oven is the one appliance almost everyone puts off. It's also the first thing a landlord opens at a move-out inspection and one of the most common reasons people book a deep clean. The good news: you don't need harsh oven cleaner or a lot of scrubbing. You need baking soda, time and a plastic scraper.
What you need
- Baking soda (about half a cup) and water
- White vinegar in a spray bottle
- A plastic scraper or old gift card — never metal on enamel
- Rubber gloves, microfibre cloths and a non-scratch sponge
- Dish soap and a bathtub or large sink for the racks
How to clean an oven, step by step
- Make sure it's off and cool. Take out the racks, the thermometer and anything else that lifts out.
- Scrape off loose debris. Burnt crumbs and big spills on the floor of the oven come up easily with a plastic scraper. Vacuum or wipe them out.
- Mix the paste. Stir about half a cup of baking soda with a few tablespoons of water until it's like spreadable icing.
- Coat the inside. With gloves on, spread the paste over the bottom, sides and inside of the door. Skip the heating elements and the fan. Thicker on the brown spots, thinner elsewhere — it will turn brownish as it works.
- Leave it overnight. Twelve hours is ideal. This is what does the hard work for you.
- Wipe it out. Use a damp cloth and the scraper to lift the paste and the grime with it. Rinse the cloth often.
- Spray vinegar on what's left. Any remaining baking soda will foam. Wipe again with a clean damp cloth until no white film is left.
- Dry and put the racks back. Run the oven empty for 10–15 minutes at a low temperature to dry it fully.
| Oven condition | Hands-on time | Waiting time |
|---|---|---|
| Light — a few drips | 15–20 minutes | A few hours of paste is enough |
| Average — regular use, cleaned a year ago | 30–40 minutes | Overnight |
| Heavy — thick, baked-on grease | 45–60+ minutes | Overnight, then a second round |
Racks and door glass
Racks: lay an old towel in the bathtub (it protects the tub), put the racks on top, cover them with the hottest tap water you have and add a good squirt of dish soap — or a few dishwasher tabs for heavy grease. Leave them a few hours or overnight, then scrub with a non-scratch sponge and rinse.
Door glass: the inside of the glass gets the same baking soda paste. Many oven doors have a gap between two panes where drips run down. Your manual will tell you if the door lifts off or the inner pane is designed to come out; if not, leave it, because forcing it can break the seal or the glass.
The door seal: wipe the rubber or woven gasket gently with warm soapy water. Don't scrub it or soak it — a damaged seal lets heat escape.

See my deep clean price →Should you use the self-clean setting?
Self-clean heats the oven to a very high temperature and burns residue to ash. It works, but it has trade-offs:
- It can take several hours and the kitchen gets hot.
- It produces smoke and smells, especially on a dirty oven — open a window and run the hood fan.
- Keep pet birds well away from the kitchen; fumes from very high oven temperatures can be dangerous to them.
- Take the racks out first unless your manual says they can stay in.
- Many manufacturers say not to use commercial oven cleaner on the inside of a self-cleaning oven, because it can damage the special coating. Check your manual before you use any spray.
Some newer ovens have a short "steam clean" setting instead. It's gentler and only handles light soil — think of it as maintenance between real cleans.
Mistakes that damage ovens
- Steel wool or metal scrapers on enamel or glass. They scratch, and scratches hold grime.
- Spraying the heating elements, fan or gas burner ports. Clean around them.
- Mixing cleaners. Never combine oven cleaner, bleach, ammonia or vinegar. Use one thing at a time and rinse in between.
- Foil on the oven floor. It can block airflow and, on some ovens, damage the bottom. Use a baking sheet on the rack below instead.
How to keep your oven clean
- Put a baking sheet under anything that could bubble over — pies, lasagna, roasts.
- Wipe spills once the oven is cool, before they bake on again next time.
- Do a quick baking soda clean every three to six months, depending on how much you cook.
The oven is usually part of a bigger kitchen reset. Our kitchen deep cleaning checklist covers the fridge, cabinets and range hood too. Moving out? The oven is the first thing on our BC move-out checklist.
Frequently asked questions
What is the easiest way to clean an oven?
Coat the inside with a paste of baking soda and water, leave it overnight, then wipe it out and spray any leftover paste with vinegar before a final wipe. The paste does most of the work for you.
How long should baking soda sit in the oven?
Overnight, or about 12 hours, for an average oven. A few hours is enough for light spills. Very heavy grease may need a second round.
Can I use oven cleaner in a self-cleaning oven?
Many manufacturers say not to, because it can damage the interior coating. Check your oven's manual first.
How do I clean between the oven door glass?
Some oven doors lift off or have an inner pane designed to come out — your manual will say. If yours doesn't, clean the glass you can reach and leave the rest rather than forcing it.
Does a deep clean include the inside of the oven?
Yes. At Good Maid, the inside of the oven is part of every deep clean and move in/out clean. A standard clean wipes the outside of the oven and the stovetop.
