Most people believe their kitchen is reasonably clean. Counters get wiped, dishes get washed, the floor gets mopped. But when the Pro Cleaning 1 team walks into a kitchen for the first time, we almost always find the same things: years of grease buildup in places that get overlooked, appliances that have never been cleaned inside, and surfaces that look fine from a distance but harbor significant bacterial buildup up close.
This is not a criticism — it is just reality. A kitchen used daily accumulates grime in ways that are easy to miss unless you know exactly where to look. In this guide, we walk through the areas that most homeowners miss during kitchen cleaning — and explain how our professional kitchen cleaning service in South Gate handles every one of them.
1. The Inside of the Oven
This is the single most commonly skipped kitchen cleaning task. Oven interiors accumulate burnt-on food residue, carbonized grease, and baked-in splatter over months and years of use. Most people use the self-clean function occasionally — but self-clean cycles do not fully remove all residue and can release smoke and fumes that are unpleasant at best.
What actually gets the oven properly clean is a manual deep clean using commercial-grade oven degreaser, non-abrasive scrubbing pads, and careful attention to the interior walls, the oven door glass (inside and out), the door seals, and the oven floor.
Left uncleaned, oven residue smokes every time you cook at high heat — affecting the flavor of your food, the air quality in your kitchen, and potentially triggering smoke detectors.
2. The Refrigerator Interior — All of It
Most people remove old food from the fridge occasionally and maybe wipe a shelf that had a spill. But a true refrigerator deep clean means:
- Removing every shelf, drawer, and divider
- Washing all removable components in hot soapy water
- Cleaning the interior walls, ceiling, and door shelves
- Cleaning the rubber door seals — where mold commonly grows unnoticed
- Wiping down the freezer interior
- Cleaning the drip tray underneath the fridge if accessible
The door seals are particularly important. Mold grows in the folds of rubber seals because moisture gets trapped there. This mold is directly adjacent to your food — and most people never think to clean it.
3. Under and Behind Appliances
Pull your refrigerator away from the wall. What you find there — dust, food debris, grease accumulation, and sometimes significant amounts of buildup — is what your kitchen floor actually looks like in the spots that never get mopped.
The same applies to the stove, dishwasher, and microwave. Under and behind appliances are among the most bacteria-rich, pest-attracting areas in any kitchen — and they are almost never cleaned during regular maintenance.
Pro Cleaning 1 moves appliances during deep kitchen cleans to access and clean these areas properly. For most homeowners, this is the most visually dramatic part of a professional clean — because the before and after difference is significant.
4. Range Hood Filters
Your range hood exists to capture grease and smoke from cooking. Which means its filters collect a significant amount of grease over time. A filter that has never been cleaned — or has not been cleaned in a year or more — is not just dirty. It is a potential fire hazard.
Grease-saturated range hood filters are highly flammable. Beyond safety, a clogged filter cannot effectively capture grease from the air — meaning more grease lands on surrounding surfaces and is recirculated through your kitchen.
Filters should be removed and cleaned in hot soapy water monthly if you cook frequently, or at minimum every 2–3 months. Our kitchen deep clean service includes filter cleaning and inspection.
5. Cabinet Fronts and Hardware
Kitchen cabinet fronts are one of the fastest-accumulating grease surfaces in the home. Every time something is fried or sautéed, fine grease particles travel through the air and settle on every surface — including cabinet doors. Combined with fingerprints and daily contact, cabinet fronts develop a sticky, yellowish film that is very difficult to remove with standard cleaning spray.
This is one of the areas where professional cleaning products make a real difference. Commercial degreasers cut through this film in ways that household sprays do not — and the difference in the appearance of cabinets after a professional clean is immediately noticeable.
6. Tile Grout
Kitchen floor grout and backsplash grout both accumulate staining, bacteria, and in high-moisture areas, mold. Grout is porous — it absorbs oils, food particles, and water. Regular mopping cleans the tile surface but does not penetrate grout deeply enough to remove embedded staining and bacteria.
Deep cleaning grout requires a stiff grout brush, a commercial cleaning solution, and time. The result — bright, clean grout lines rather than gray or brown ones — transforms the entire appearance of a kitchen floor or backsplash.
7. The Sink — Properly
Most people consider the kitchen sink clean when it looks clean. But research consistently shows that kitchen sinks contain more bacteria than almost any other surface in the home — including toilet seats. The drain, the basin edges, around the faucet base, and the underside of the faucet head are all areas where bacteria accumulate significantly.
A proper sink clean means scrubbing the basin with an abrasive cleaner, disinfecting all surfaces, descaling the faucet to remove mineral deposits, cleaning around and inside the drain, and sanitizing the dish rack and soap dispenser area.
8. The Trash Can — Inside and Out
When did you last clean the inside of your kitchen trash can? For most people, the answer is never — or not recently. Even with a liner, liquids leak, food particles fall to the bottom, and bacterial growth builds up over time.
Trash cans should be washed out with hot water and a disinfectant spray at least monthly — more frequently in summer when bacterial growth accelerates. The lid and exterior should be wiped down weekly.
9. Light Switches, Outlet Covers, and Cabinet Knobs
These are touched constantly — with hands that have been handling food, raw meat, and cooking residue. They accumulate bacteria at a higher rate than many kitchen surfaces but are almost never cleaned specifically.
A proper kitchen deep clean includes wiping down and disinfecting all switches, outlet covers, cabinet knobs, and drawer handles — the high-touch surfaces that get overlooked in standard cleaning routines.
10. The Dishwasher Interior
A dishwasher cleans your dishes, but it also collects food debris, grease, and limescale over time. The filter at the bottom of the dishwasher — which many people do not even know exists — can become clogged with food particles, reducing cleaning effectiveness and causing unpleasant odors.
Monthly: remove and clean the filter, wipe down the door seals, and run a cleaning cycle with a commercial dishwasher cleaner or white vinegar.
