9 Kitchen Areas You Should Clean Weekly (But Probably Don’t)

Think your kitchen is clean? You might want to look again. Even if you wipe down your counters daily and keep your sink spotless, there are kitchen areas you should clean weekly that most people forget — and they may be dirtier than you think.

Hidden grime, sticky handles, and germ-filled seals quietly build up over time, inviting odors, bacteria, and even pests. In this article, we’ll reveal the most overlooked kitchen cleaning tasks and why including them in your weekly kitchen cleaning checklist is essential for a truly healthy home.

• Most people forget to clean high-touch or hidden spots like cabinet handles, sink drains, and appliance buttons.

• Skipping these areas can lead to bacteria buildup, mold, and unpleasant smells.

• A consistent weekly kitchen cleaning checklist can keep your space hygienic and stress-free.

• Just 15 extra minutes a week can protect your family from invisible kitchen messes.

1. Cabinet Handles and Drawer Pulls

You open drawers, grab plates, and pull out utensils multiple times a day — but when was the last time you cleaned the handles? These tiny touchpoints accumulate everything from greasy fingerprints to raw food bacteria. According to a 2022 study by the National Sanitation Foundation (NSF), cabinet handles are among the dirtiest kitchen surfaces, often harboring coliform bacteria from raw meat and unwashed hands.

What Gets Missed:

• Edges around knobs and pulls

• Grease streaks near cooking zones

• The underside of frequently used drawer handles

How to Clean:

• Spray handles with a multi-surface disinfectant or vinegar solution

• Let sit for 1–2 minutes

• Wipe with a microfiber cloth

• Repeat weekly — more often if you cook frequently

Tip: For stainless steel pulls, use a dedicated stainless cleaner to avoid streaks.

2. Under the Sink Area

It’s easy to stash your cleaning supplies under the sink and forget the space even exists — but that’s what makes it a breeding ground for mold, mildew, and pests. The dark, damp environment is one of the most neglected kitchen areas to clean, especially if you’ve had a slow leak or leftover food scraps nearby.

What Gets Missed:

• Leaky pipe drips on the base of the cabinet

• Sticky cleaner residue

• Forgotten sponges or cloths that harbor bacteria

How to Clean:

• Take everything out — including bins and bags

• Wipe down surfaces with a disinfectant

• Check for mold or moisture under liner mats

• Let dry fully before replacing items

• Do this once a week to catch small problems early

Real-World Example:
A homeowner in a 2023 Better Homes & Gardens case study found black mold under the sink that had gone unnoticed for over 6 months — caused by a slow leak.

Pro Tip: Always store cleaning supplies in sealed containers to prevent leaks and reduce exposure to fumes or cross-contamination.

3. Fridge Shelves and Door Seals

Even though it stores your food, your fridge might be dirtier than your bathroom — especially if you ignore the gaskets and inner edges. Food drips, crumbs, and moisture collect in hard-to-see spots like shelf seams and rubber seals.

A 2021 NSF study found that door seals often test positive for mold and yeast, yet most people never clean them unless something spills.

What Gets Missed:

• Crumbs under crisper drawers

• Sticky shelf corners

• Moldy buildup inside door gaskets

How to Clean:

• Remove food items and wipe each shelf with a solution of warm water + mild dish soap

• Use a toothbrush or cloth to gently scrub door seals

• Rinse with clean water and let dry

• Clean at least once a week, especially near dairy and meat compartments

4. Microwave and Small Appliance Buttons

Microwave buttons, toaster dials, and blender switches are some of the dirtiest small surfaces in the kitchen — but they’re rarely cleaned unless something spills. Think about it: you touch them with greasy, floury, or raw-chicken-contaminated fingers, then forget they ever existed.

According to a 2022 report by the Journal of Environmental Health, appliance buttons are high-risk for bacterial transfer, especially in households with children or pets.

What Gets Missed:

• Around microwave keypads

• Crusty buildup on blender and mixer switches

• Toaster levers and knobs with crumbs or oils

How to Clean:

• Unplug the appliance before cleaning

• Use a slightly damp microfiber cloth with dish soap or white vinegar

• For stuck-on gunk, use a soft-bristle toothbrush

• Wipe dry with a clean cloth

• Add to your weekly kitchen cleaning checklist

Can I use disinfectant wipes on my microwave buttons?
Yes — just make sure they’re not overly wet, and never let liquid seep into digital displays.

5. Sink Drain and Garbage Disposal Flap

If your kitchen smells weird even after cleaning, check your sink drain and garbage disposal. This is one of the fastest places for grime and bacteria to build up — food scraps, moisture, and grease create the perfect storm for odor and mold.

A Consumer Reports 2023 kitchen study revealed that sink drains had more bacteria than toilet seats in over 50% of tested homes.

What Gets Missed:

• Inside the disposal unit flap

• The slimy area around the drain ring

• Mold under the metal stopper

How to Clean:

• Sprinkle baking soda down the drain

• Add white vinegar and let it fizz for 10 minutes

• Scrub the drain ring and disposal flap with a brush

• Flush with hot water or boiling water

• Do this once per week to prevent slime and smells

Real-Life Example:
A mom blogger from Houston shared that a mystery smell in her kitchen turned out to be a moldy garbage disposal flap — cleaned weekly now, smell gone.

Pro Tip: Never pour grease down the drain — it clogs the pipe and attracts bacteria.

6. Stove Backsplash and Hood

While you’re scrubbing pots and pans, you probably ignore the stove backsplash and range hood. But every time you cook, grease and steam splash upward, sticking to the walls and vents. Over time, this can become a grimy mess — or even a fire hazard if not addressed.

Kitchen appliance brand GE Appliances recommends wiping your backsplash at least once a week, especially if you cook with oil.

What Gets Missed:

• Tile grout lines or wall edges behind the stove

• The underside of the hood (where grease drips)

• Air vents clogged with dust and residue

How to Clean:

• Spray backsplash with degreasing cleaner or vinegar + dish soap

• Wipe using a sponge or non-abrasive scrubber

• Use a degreaser or mild dish soap on hood surfaces

• Remove and clean vent filters monthly (or per use instructions)

Tip: If your backsplash is glass or stainless steel, use a soft cloth to avoid scratching.

7. Utensil Drawer and Organizers

It may look tidy when you open it, but underneath your cutlery trays lie crumbs, lint, and sticky spills that often go unnoticed. Every time you toss in a damp spoon or freshly washed utensil, you risk adding bacteria to your drawer.

A 2021 study by The Microbiology Society found high levels of bacteria in utensil trays, especially in drawers that hadn’t been cleaned in 30 days or more.

What Gets Missed:

• The bottom of the drawer under organizers

• Dust or food particles that slide under trays

• Sticky residue from wet utensils

How to Clean:

• Take out the entire tray and all utensils

• Vacuum or wipe out crumbs and dust

• Wash tray in warm, soapy water and let it dry completely

• Wipe drawer interior and let dry before replacing items

• Repeat once a week to prevent grime buildup

Do utensil drawers really need weekly cleaning?
Yes — especially in busy households or if you store damp utensils.

8. Coffee Maker or Kettle Base

Your morning coffee may be energizing, but your coffee maker could be brewing bacteria too. The base, reservoir, and heating plate are often missed — and they can collect hard water deposits, mold, and even bugs over time.

According to Consumer Reports, one in five coffee machines tested in 2023 showed mold or yeast growth when not cleaned weekly.

What Gets Missed:

• The heating plate under the pot

• Outer body with dried coffee drips

• Inside the water tank or spout

• Base of electric kettles with water ring buildup

How to Clean:

• Descale the machine by running a cycle with 1 part white vinegar, 2 parts water

• Scrub outer body and base with mild soap

• Wipe dry with a clean towel

• Clean once a week, or more often with daily use

Note: Mold buildup in reservoirs is invisible until it becomes a health risk — regular cleaning prevents this.

9. Light Switches and Wall Areas Near Counters

They’re everywhere — and they’re filthy. Light switches, outlet plates, and the walls around food-prep zones are often splashed, smeared, or touched with dirty hands. And yet, they’re almost never on the cleaning list.

A 2022 Good Housekeeping kitchen hygiene audit found more bacteria on wall switches and nearby splash zones than on toilet handles.

What Gets Missed:

• The switch plate’s edges

• Wall splatters from mixing or cooking

• Greasy fingerprints near counters

How to Clean:

• Use a disinfectant wipe or damp cloth with soap

• Don’t oversaturate — moisture can damage outlets

• Wipe walls around food prep areas too

• Clean these once per week, or after messy meal prep

Tip: Keep a small pack of cleaning wipes in a nearby drawer for fast touch-ups.

How to Build a Weekly Kitchen Cleaning Routine

Cleaning your kitchen weekly doesn’t have to feel overwhelming. It’s not about scrubbing your entire kitchen top to bottom — just about staying ahead of the grime in the areas that matter most.

Realistic Weekly Routine Tips:

• Break it down: Tackle 2–3 areas per cleaning session (e.g., Mon: appliances, Wed: sink/drain, Fri: drawers + walls)

• Set phone reminders or use smart home assistant commands

• Keep a visible checklist on the fridge or inside a cabinet

• Stock a mini cleaning caddy with wipes, spray, vinegar, and cloths
