How to Deep Clean Your Kitchen From Top to Bottom

When to Deep Clean Your Kitchen

A regular wipe-down keeps your kitchen functional. A deep clean restores it. Most Oregon households benefit from a kitchen deep clean every three to six months, or whenever grease buildup, stale odors, or discoloration signals that surface cleaning is no longer enough.

Common triggers include moving into a new home, preparing for the holidays, spring cleaning season, or simply noticing that the range hood filter is coated in brown grease. If your regular cleaning routine handles daily messes but the kitchen still feels grimy, it is time to go deeper.

Supplies You Will Need

• Degreasing spray or a mix of dish soap and baking soda
• White vinegar and water in a spray bottle (equal parts)
• Microfiber cloths (at least four — one per zone)
• Scrub brush or old toothbrush for grout and crevices
• Bucket with warm water
• Rubber gloves
• Step stool for reaching upper cabinets and the range hood
• Trash bag for expired items from the fridge and pantry

Oregon homeowners who prefer non-toxic options can find effective plant-based degreasers at most Portland and Eugene grocery stores. Our guide to eco-friendly cleaning products in Oregon lists specific brands that work well for heavy kitchen grease.

Upper Cabinets and Range Hood

Start high and work down. This way, dust and drips fall onto surfaces you have not cleaned yet.

Range Hood

The range hood filter collects airborne grease every time you cook. Remove the filter and soak it in a sink full of hot water, dish soap, and a quarter cup of baking soda for 15 to 20 minutes. While it soaks, spray the hood exterior with degreaser and wipe clean. Scrub the filter with a brush, rinse, and let it air dry before reinstalling.

Cabinet Tops and Exteriors

The tops of kitchen cabinets — especially above the stove — accumulate a sticky layer of grease and dust that standard cleaning never touches. Spray with degreaser, let it sit for five minutes, then wipe with a microfiber cloth. For painted cabinets, test a small area first. For wood, follow up with a wood-safe polish.

Cabinet door fronts around handles develop grime from daily use. A warm cloth with a drop of dish soap handles most finishes. If your kitchen has stainless steel appliances, our guide on cleaning stainless steel covers the right products and techniques to avoid scratching.

Appliances Inside and Out

Oven

If your oven has a self-clean cycle, run it the night before your deep clean. The cycle heats the oven to extremely high temperatures and turns residue to ash that you can wipe out easily the next morning. If you do not have self-clean, make a paste of baking soda and water, spread it inside the oven, let it sit overnight, then spray with vinegar and wipe clean.

Refrigerator

Remove all food. Toss anything expired. Take out shelves and drawers and wash them in warm soapy water. Wipe down the interior walls with a solution of two tablespoons baking soda per quart of water. Clean the door seals — that rubber gasket traps crumbs and mildew. For a full walkthrough, see our refrigerator cleaning guide.

Dishwasher

Run an empty cycle with a cup of white vinegar on the top rack. Then sprinkle baking soda on the bottom and run a short hot cycle. Clean the filter, door edges, and rubber gasket where food particles collect.

Microwave

Fill a microwave-safe bowl with one cup of water and half a lemon. Microwave for three minutes and let it steam for two more minutes with the door closed. The steam loosens stuck-on food so you can wipe everything clean in one pass.

Countertops and Backsplash

Different countertop materials need different approaches. Oregon homes commonly feature granite, quartz, laminate, and butcher block.

• Granite and quartz: Use a pH-neutral cleaner or warm water with mild dish soap. Avoid vinegar on natural stone — it etches the surface. For specific stone guidance, see our natural stone countertop guide.
• Laminate: Baking soda paste for stains, warm soapy water for general cleaning. Avoid abrasive pads that scratch the surface.
• Butcher block: Clean with mild soap and water. Disinfect with white vinegar. Re-oil monthly with food-safe mineral oil.

For the backsplash, spray tiles or glass with an all-purpose cleaner and scrub grout lines with a brush. Grout absorbs grease splatter and discolors over time. A paste of baking soda and hydrogen peroxide brightens grout without harsh chemicals. For extensive grout issues, see our tile and grout cleaning guide.

Sink and Faucet

Scrub the sink basin with baking soda and a sponge. For stainless steel sinks, scrub with the grain to avoid scratches. For porcelain or ceramic, a non-abrasive cleaner works best. Run hot water down the drain, then pour half a cup of baking soda followed by half a cup of vinegar. Let it fizz for 10 minutes and flush with hot water to clear buildup and odor.

Clean the faucet with an all-purpose cleaner. For hard water deposits on the faucet head, soak a cloth in white vinegar and wrap it around the fixture for 30 minutes. This dissolves mineral buildup without damaging the finish. If hard water stains are a recurring issue, see our guide on removing hard water stains.

Lower Cabinets and Drawers

Pull everything out and wipe shelves and drawer bottoms. Check for expired spices, leaking bottles, and items you no longer use. Under the sink is a common trouble spot — check for moisture, leaks, and mildew. Lay fresh shelf liner if the existing one is stained or peeling.

The kickboard area below lower cabinets collects dust and food debris that a mop cannot reach. Use a vacuum with a crevice attachment, then wipe with a damp cloth.

Floors and Baseboards

Sweep or vacuum the entire kitchen floor, including under the refrigerator and stove if you can pull them out. Mop with a cleaner appropriate for your floor type — tile, hardwood, laminate, and vinyl each have specific requirements.

Baseboards and the area where the floor meets cabinets are grease and dust magnets. Wipe them with a damp cloth and a drop of dish soap. In a deep clean, this step makes a surprising difference in how the kitchen looks overall.

Professional Deep Clean vs DIY

A DIY kitchen deep clean takes most people three to five hours depending on kitchen size and condition. If that sounds like more time than you have, a professional deep cleaning service can handle it in less time with commercial-grade products and trained crews.
