Deep-Clean Your Oven Naturally: Racks, Glass & Interior
A complete baking soda and vinegar reset that gets Greek kitchen ovens guest-ready without chemical sprays.

Whether you manage a holiday villa in Crete, run a boutique hotel kitchen, or simply want your home oven spotless before the next family roast, a deep clean should not require harsh chemical fumes or a two-hour self-clean cycle. The video above walks through the natural approach visually, and the steps below give you the full process in detail — interior walls, wire racks, and door glass — using only baking soda, white vinegar, and a little patience. This method is safe for any standard oven and leaves no chemical residue, which matters especially in rental properties where guests may be sensitive to cleaning product smells.
Why Skip Chemical Sprays and the Self-Clean Function?
Commercial oven cleaners contain sodium hydroxide (lye), which strips grease effectively but leaves a strong odour and requires thorough rinsing before the oven is food-safe again. In a Greek holiday rental that turns over quickly, the last thing you want is a guest's first meal tasting of chemical residue.
The self-clean function reaches temperatures above 400 °C, which can warp oven racks, damage door gaskets over time, and fill the kitchen with smoke from burning-off grease — not ideal when you have guests arriving in the afternoon. The baking soda method takes longer to sit but requires almost no scrubbing and leaves the oven completely safe to use immediately afterwards.
What You Will Need Before You Start
Gather these before you begin: a box of bicarbonate of soda (baking soda), a spray bottle filled with plain white vinegar, a silicone or rubber spatula, a non-scratch scrubbing pad, a large bin bag or plastic sheet, rubber gloves, and a damp cloth. You will also need access to a bathtub or a large sink for soaking the racks.
One full deep-clean works best when the oven is completely cold and empty. Remove any oven thermometers, pizza stones, or liners before starting. Budget around 12 hours total — mostly unattended overnight soaking time — so plan this for an evening before a free morning.
The 5-Step Natural Oven Deep-Clean
- 1
Soak the Wire Racks Overnight
Remove all racks and lay them flat in the bathtub. Cover them with hot water and add half a cup of baking soda and a generous splash of washing-up liquid. Leave them to soak overnight. By morning, baked-on grease will have loosened enough to wipe away with a non-scratch pad and very little effort. Rinse thoroughly and dry before returning them to the oven.
- 2
Coat the Interior Walls with Baking Soda Paste
Mix roughly half a cup of baking soda with two to three tablespoons of water until you have a spreadable paste — the consistency of thick yoghurt. Using gloved hands or a pastry brush, coat every interior surface: the back wall, side walls, floor, and ceiling of the oven. Avoid the heating elements and any exposed wires. The paste will turn brown as it contacts grease, which is normal. Leave it for at least 12 hours (overnight is ideal).
- 3
Wipe Out the Loosened Paste and Grease
After the soak, use a damp cloth or silicone spatula to wipe away the dried paste. Work from the top down so loosened debris falls to the oven floor where you can collect it last. A damp cloth is usually sufficient for most surfaces; use the non-scratch pad on any stubborn carbonised spots. Remove as much of the paste as possible before the next step.
- 4
Spray with White Vinegar to Neutralise and Lift Residue
Fill a spray bottle with undiluted white vinegar and spray all the surfaces you just wiped. The vinegar reacts with any remaining baking soda, creating a brief fizzing action that lifts residue and neutralises the alkaline paste. Wipe down again with a clean damp cloth, rinsing the cloth regularly. Repeat the spray-and-wipe cycle until the surfaces look clean and the cloth comes away without brown smears.
- 5
Clean the Door Glass from Both Sides
The glass is often the most visible part of the oven and the easiest to overlook. Make a fresh paste of baking soda and water, apply it to the interior face of the glass, and leave it for 20 to 30 minutes. Wipe off with a damp cloth, then spray with vinegar and buff with a dry microfibre cloth until clear. For the exterior face, the same method works, or a simple spray of diluted vinegar followed by a dry buff is usually enough to remove fingerprints and splatter.

FAQ
- How long does the natural oven cleaning method take from start to finish?
- Active hands-on time is around 30 to 40 minutes split across two sessions. The bulk of the time — 12 hours or more — is unattended soaking. Start the rack soak and apply the interior paste on the same evening, then complete the wipe-down and vinegar step the following morning. The oven is ready to use as soon as it is dry.
- Will baking soda damage the oven's enamel or heating elements?
- Baking soda is mildly alkaline and safe on standard vitreous enamel oven interiors. The key is to avoid applying the paste directly onto exposed electric heating elements or gas burner ports — simply paste around them. Some manufacturers advise against leaving any substance on the elements, so wipe those areas clean with a plain damp cloth.
- How often should a holiday rental or hotel kitchen oven be deep-cleaned this way?
- For a busy holiday rental with weekly changeovers, a full deep-clean at the start and end of each season (twice a year) is the practical minimum, with a light wipe-down of the interior after heavily used weeks. Hotel and professional kitchen ovens that see daily use benefit from a monthly deep-clean and a quick vinegar wipe after each shift to prevent grease build-up from carbonising.
