Cleaning your kitchen is a never-ending task, but even with the best of intentions, some areas can slip past your radar and build up over time.

I'm a longstanding professional cleaner for a commercial and residential cleaning company, and these are the seven things I can't help but always spot in people's homes.

With my cleaning tips, you'll be able to tackle these quickly and cheaply before hosting season kicks off.

7 dirty things I always notice in people's kitchens

1. Greasy cabinet doors

Cabinet doors, especially around the stove, often have a buildup of grease and fingerprints that aren’t immediately noticeable until the grime sets in.

To clean your kitchen cabinets, mix a solution of warm water and a few drops of dish soap, then wipe with a soft cloth. For stubborn spots, use a splash of white vinegar, available at Walmart, to cut through the grease.

I am a professional cleaner and operations manager at Spekless, and I like to buy in bulk and use Dawn Powerwash Spray, available on Amazon. It's great for spot-cleaning grease on cabinets and I find this spray breaks down oils instantly, allowing for quick wipe-downs.

My pro tip: Wipe down cabinet doors weekly with a microfiber cloth and plain water to prevent grease buildup.

2. Sticky handles and knobs

These areas are touched constantly and often hold onto residue from food or grease, making them a hot-spot for household bacteria, one of the surprisingly most dirtiest parts of the home.

To clean, dampen a microfiber cloth with a water-vinegar mix (1:1 ratio) and wipe down each handle thoroughly.

I like using the Mr. Clean Magic Eraser Sheets – These sheets are perfect for quickly scrubbing stubborn spots without damaging surfaces. They're also disposable, heavy-duty and great for tackling any hard-to-reach areas of your home, such as behind your toilet or the back of cabinets.

I advise wiping door handles and knobs every few days as part of your regular kitchen cleaning, or after preparing food with greasy ingredients to keep them clean and bacteria-free.

Punteha van Terheyden, head of Solved at H&G adds, 'If you have pets, watch out for corner of your lower cabinets too. My two cats love to rub themselves on the same cabinet multiple times a day and there's often a greasy little mark where they head bump the corner.

'I wipe this section down when I clean the handles using a homemade essential oil cleaning spray using 10-20 drops of geranium essential oil, available at Walmart, water, an a tiny squeeze of dish soap.' The dish soap acts as surfactant, helping cut through the grease.

3. Sink faucets and handles

Getting rid of hard water stains and soap scum is a regular churn in most homes as the these often accumulate on faucets, especially in areas with high mineral content in the water.

The H&G team have tested a few ways, including cleaning faucet limescale with toothpaste, or tackling stubborn faucet hard water stains with lemon, which both worked well.

I also like to use a paste of baking soda, available at Walmart, and water to scrub the faucet, then rinse and buff with a dry cloth for a streak-free finish. The baking soda makes a natural, cheap and gentle but effective scrubbing agent which is why it's great for mineral deposits.

My pro tip: Dry faucets after each use, or apply a thin layer of wax paper, such as Reynold's Wax Paper on Amazon monthly to reduce water spots. It might sound hard to believe but one of the H&G team stopped faucet marks using candle wax and found it lasted a week at a time.

4. Under and around small appliances

Crumbs and sticky residue often hide under appliances like the toaster, microwave, or coffee maker, leading to both grime and the potential for pest issues.

Move appliances weekly and use a damp microfiber cloth with a bit of dish soap to wipe the area clean. Rinse and dry before placing appliances back. I like to use these microfiber cleaning cloths from Amazon as they are highly absorbent and trap dirt and crumbs effectively.

My pro tip: Place a thin, washable mat, such as the food-grade silicone kitchen countertop protector mat from Amazon, under small appliances for easy cleanup.

5. Fridge door seals

The seals around fridge doors often harbor crumbs, sticky residue, and even mold, as they’re prone to collecting trapped moisture. Learn more about the most common types of household mold.

To clean mold from a refrigerator door seal, dip an old toothbrush in a mix of water and baking soda, then scrub around the seals. Wipe away any residue with a damp cloth.

I recommend the Rubbermaid Reveal Power Scrubber – This scrubber is excellent for cleaning tight spaces like fridge seals, providing quick and effective results.

My pro tip: Wipe down seals monthly and ensure the fridge closes properly to avoid moisture buildup.

6. Microwave interior

It's one of the quiet workhorses of the everyday kitchen, with spills and splatters easily happen in microwaves. These often get left behind, leading to odors and hardened food debris.

For a cheap and effective method, learn how to clean a microwave with lemon. All you use a suitable bowl that's safe to use in the appliance, fill with water and a few slices of lemon, then microwave for three to five minutes. Let it sit for another two minutes, allowing the steam to loosen up the grime before wiping it down.

If you have really baked on stains or prefer a commercial cleaner, the Lysol Power Kitchen Cleaner, available at Amazon, is ideal for any lingering spots. This spray works well for microwave cleaning and neutralizing odors, which can become a part of microwave use if yours is not regularly cleaned.

My pro tip: Cover food with a microwave-safe lid to prevent splatters and wipe out the interior weekly.

7. Trash can lid and surrounding floor area

Food scraps and liquids often end up on the lid or around the trash can, creating sticky spots that attract dirt and odors. Wipe down the trash can lid and nearby floor area with an all-purpose cleaner and dry it with a cloth weekly.

The Simple Green All-Purpose Cleaner is versatile and safe on most surfaces, effectively removing residue and odor around trash cans.

My pro tip: Whenever you are replacing your cleaning sponge, squirt some dish soap onto it and use it to scrub the inside of the trash can lid, then bin it. The gentle scouring action combined with the grease-busting dish soap will tackle any dried on stains and you can bin it without guilt as it was bound for the trash anyway.
