To deep clean a kitchen effectively, you must follow a top-down approach that starts with degreasing high surfaces and ends with floor sanitisation. This process typically takes between three and five hours for a standard UK kitchen, focusing on internal appliance cleaning, cupboard decluttering, and removing limescale from fixtures.
What is the difference between a surface clean and a deep clean?
A surface clean focuses on visible hygiene, such as wiping worktops and sweeping floors, whereas a deep clean targets accumulated grime in hidden areas. Deep cleaning involves moving appliances to clean behind them, scrubbing oven interiors, descaling taps, and emptying every cupboard to sanitise the internal shelving.
Most households benefit from a deep clean every three to six months. Regular maintenance keeps the space functional, but oils from cooking aerosolise and settle on tops of cabinets and light fixtures, creating a sticky layer that attracts dust. Addressing this requires specific degreasing agents and dedicated time that goes beyond a daily ten-minute tidy.
How to prepare for a kitchen deep clean?
Preparation involves gathering all necessary supplies and clearing the surfaces to ensure you have an unobstructed workspace. You should start by emptying the dishwasher and clearing the sink so you have a staging area for washing internal fridge shelves or cupboard organisers.
Ensure you have the following supplies ready before you begin:
- A dedicated kitchen degreaser or a mixture of white vinegar and dish soap.
- Bicarbonate of soda for abrasive scrubbing on stubborn stains.
- Microfibre cloths (at least six to avoid cross-contamination).
- A non-scratch scouring pad and an old toothbrush for tight gaps.
- Limescale remover or citric acid for the sink and kettle.
- Glass cleaner for windows and reflective appliance fronts.
Step 1: Apply treatments to the heavy-duty areas
The most efficient way to clean is to let cleaning products sit on difficult surfaces while you work elsewhere. Start by applying oven cleaner to the interior of your oven and soaking the racks in a tray of warm, soapy water. If you have a dishwasher, run a cleaning cycle with a dedicated descaler. Put your kettle on to descale using a mixture of half water and half white vinegar, letting it sit for 30 minutes.
Step 2: Clean from the ceiling down
Gravity dictates that dust and debris will fall as you clean. Start with the tops of wall-mounted cupboards, which are often the greasiest areas in the room. Use a concentrated degreaser to break down the sticky film. Wipe down light fixtures, the tops of picture frames, and the corners of the ceiling to remove cobwebs. Clean the extractor fan filters; if they are metal, most can be placed in the dishwasher. If they are fabric, they likely need replacing.
Step 3: Empty and sanitise cupboards and drawers
Work around the room clockwise. Empty one cupboard at a time. Check the expiry dates on all food items and discard anything that is no longer safe to eat. Wipe the internal shelves with a damp cloth and dry them thoroughly before replacing items. This is a good time to reorganise your life-hacks for storage, such as grouping baking goods together or placing frequently used spices at the front.
| Area | Focus Task | Estimated Time |
|---|---|---|
| Oven & Hob | Burnt-on carbon and grease removal | 45 minutes (active) |
| Fridge & Freezer | Shelf washing and food auditing | 40 minutes |
| Upper Cabinets | Degreasing tops and internal dusting | 30 minutes |
| Small Appliances | Descaling kettle and crumb removal | 20 minutes |
| Sink & Taps | Limescale removal and drain freshening | 15 minutes |
Step 4: Deep clean the refrigerator
Remove all food and place perishables in a cool bag if you expect the process to take longer than 20 minutes. Remove shelves and drawers, washing them in the sink with warm soapy water. Wipe the interior walls of the fridge, paying attention to the drainage hole at the back, which can become blocked with slime or food debris. Dry everything before reassembling to prevent mould growth. For more on maintaining a healthy home environment, see our guide on health and wellness.
Step 5: Scrub the worktops and splashbacks
Move everything off the counters, including the toaster, microwave, and bread bin. Clean the wall behind these items, as splashes from cooking often dry and harden there. If you have stone worktops, ensure you use a pH-neutral cleaner to avoid etching the surface. Use a toothbrush to scrub the grout lines between tiles and the seal between the worktop and the wall.
Step 6: Finish the oven and sink
By now, the cleaning agents in the oven will have loosened the grime. Scrub the interior and rinse thoroughly. For the sink, scrub away the limescale that has been softening. Polish the taps with a dry microfibre cloth to achieve a shine. Pour boiling water down the drain to clear any remaining soap residue.

Step 7: The floor
Vacuum or sweep the floor, ensuring you get into the kickboards under the cabinets. Mop the floor using hot water and a floor cleaner suited to your surface type (wood, tile, or laminate). Start at the furthest corner and work your way toward the door so you do not step on the clean, wet surface. Allow it to air dry completely before walking on it.
Frequently asked questions
How do I remove the sticky grease from the top of kitchen cabinets?
The best method is to use a dedicated heavy-duty degreaser or a paste made of bicarbonate of soda and a little water. Apply the paste, let it sit for 5 minutes, and then scrub gently with a non-scratch sponge. Once the grease is gone, wipe the area with a clean, damp cloth to remove any residue.
Can I clean my oven without harsh chemicals?
Yes, you can use a paste of bicarbonate of soda and water. Spread it over the oven surfaces (avoiding the heating elements) and leave it overnight. In the morning, spray the dried paste with white vinegar, which will cause it to foam, then wipe it away with a damp cloth. This is effective for moderate grease but may require more physical scrubbing than commercial cleaners.
How often should I descale my kettle and dishwasher?
In hard water areas, you should descale these appliances every month to maintain efficiency and prevent mechanical failure. In soft water areas, every three to six months is usually sufficient. Regular descaling can reduce energy consumption by ensuring heating elements work correctly.
What is the best way to clean a microwave?
Place a bowl of water with a few lemon slices or a tablespoon of vinegar inside the microwave. Heat it on high for 3 to 5 minutes until the window steams up. Leave the door closed for another 5 minutes to let the steam loosen dried food, then simply wipe the interior clean with a cloth.
