You wipe your counters. You do the dishes. You might even sweep the floor on a good day. But when's the last time you actually cleaned the things doing the heavy lifting in your kitchen?
Your oven, dishwasher, coffee maker, and microwave accumulate grime, grease, mineral deposits, and sometimes genuinely alarming things you'd rather not think about. The good news: deep cleaning them is easier than you think, you probably already have everything you need, and the results are immediately satisfying.
Here's your appliance-by-appliance guide. Pick one this weekend, or tackle them all over the next few weeks. Your kitchen will thank you.
The Oven
How often: Every 3–6 months, or whenever you notice buildup or smoke during preheating.
What you'll need: Baking soda, white vinegar, dish soap, spray bottle, damp cloths, a plastic or silicone scraper.
Steps:
1. Remove the racks. Take them out and soak them in your bathtub or a large basin with hot water and a generous squirt of dish soap. Let them soak for at least 2 hours (overnight is better).
2. Make the paste. Mix ½ cup baking soda with enough water to form a thick, spreadable paste. Add a few drops of dish soap if you want extra grease-cutting power.
3. Coat the interior. Spread the paste over every interior surface — walls, floor, ceiling, door glass. Avoid the heating elements. The paste will turn brown as it reacts with the grease. That's a good thing.
4. Wait. Leave the paste on for at least 12 hours. Overnight is ideal. This is a patience game — the baking soda does the work so you don't have to scrub yourself raw.
5. Wipe it out. Use damp cloths to wipe away the paste. A plastic scraper helps with stubborn spots. For any remaining residue, spritz with white vinegar — it'll fizz and loosen what's left.
6. Scrub the racks. After soaking, scrub with a brush or the rough side of a sponge. Rinse, dry, and slide them back in.
7. The door glass. If the space between the glass panes is grimy, check your oven's manual — many models let you remove the door or access the gap. For the outer glass, the baking soda paste works perfectly.
Pro tip: Line the bottom of your oven with a silicone oven liner or a sheet of foil after cleaning. It catches drips and makes next time's deep clean much easier.
The Microwave
How often: Monthly, or whenever it starts looking (or smelling) like a crime scene.
What you'll need: A microwave-safe bowl, water, lemon or vinegar, a sponge or cloth.
Steps:
1. Steam it. Fill a microwave-safe bowl with 1 cup of water and either ½ a lemon (squeezed, then dropped in) or 2 tablespoons of vinegar. Microwave on high for 3–5 minutes until the window is steamy.
2. Let it sit. Don't open the door for 5 minutes. The steam loosens everything — splatters, dried sauce, that mysterious explosion from last month.
3. Wipe it down. Open the door and carefully remove the bowl (it's hot). Wipe every surface with a damp cloth or sponge. Everything should come off easily. For stubborn spots, dip your sponge in the lemony water and apply a little pressure.
4. Don't forget the turntable. Remove it, wash it in the sink like a dish, dry it, and put it back.
5. Clean the exterior. Wipe down the door, handle, and control panel. A damp cloth with a drop of dish soap works. Dry with a clean cloth to avoid streaks.
Pro tip: Keep a microwave-safe cover or a damp paper towel over food while heating. It catches splatters before they happen, and you'll barely need to deep clean at all.
The Dishwasher
How often: Once a month. Yes, the thing that cleans your dishes needs cleaning too.
What you'll need: White vinegar, baking soda, a toothbrush or small brush, dish soap.
Steps:
1. Clean the filter. This is the part most people skip — and it's the most important. Pull out the bottom rack, find the filter (usually a cylindrical piece at the base), twist and remove it. Rinse it under hot water, scrubbing with a toothbrush to remove trapped food and grease. If it's really bad, soak it in warm soapy water for 10 minutes first.
2. Check the spray arms. Look at the holes where water sprays out. If any are clogged (you'll see mineral buildup or food bits), use a toothpick or thin wire to clear them. This alone can dramatically improve your dishwasher's performance.
3. Wipe the door edges and gasket. The rubber seal around the door collects grime, mildew, and forgotten food bits. Wipe it with a damp cloth dipped in vinegar. Use a toothbrush for the crevices.
4. Run a vinegar cycle. Place a cup of white vinegar in a dishwasher-safe container on the top rack. Run a hot water cycle with nothing else in the machine. The vinegar cuts grease, removes odors, and dissolves mineral deposits.
5. Follow with baking soda. After the vinegar cycle finishes, sprinkle a cup of baking soda on the bottom of the dishwasher. Run a short hot cycle. This brightens the interior and neutralizes any remaining odors.
Pro tip: If your dishwasher smells funky between deep cleans, it's almost always the filter. A quick rinse every week or two prevents buildup and keeps things fresh.
The Coffee Maker
How often: Monthly for deep cleaning. Rinse removable parts after every use.
What you'll need: White vinegar, water, a clean cloth, and whatever gentle brush fits your model.
Steps for drip coffee makers:
1. Fill the reservoir. Mix equal parts white vinegar and water. Fill the full reservoir with this solution.
2. Run half a cycle. Start a brew cycle with no coffee grounds or filter. Halfway through, turn it off and let the solution sit for 30–60 minutes. This soaks the internal tubing where mineral deposits hide.
3. Finish the cycle. Turn it back on and let it complete.
4. Rinse twice. Run two full cycles with plain water to flush out the vinegar. Nobody wants vinegar-flavored coffee.
5. Clean the carafe and basket. Wash with warm soapy water. For coffee stains in the carafe, add ice, a tablespoon of salt, and a squeeze of lemon — swirl vigorously and the abrasion will lift the stains.
For single-serve machines (Keurig, Nespresso, etc.):
1. Empty and rinse the water reservoir.
2. Fill with a vinegar-water solution (or use the manufacturer's descaling solution).
3. Run brew cycles without a pod until the reservoir is empty.
4. Refill with plain water and run 3–4 rinse cycles.
5. Wipe the pod holder area with a damp cloth — coffee grounds accumulate here more than you'd expect.
Pro tip: If you have hard water, you'll need to descale more often — every 2–3 weeks. You'll know it's time when your coffee maker starts brewing slower or making weird noises.
The Garbage Disposal
How often: Every 2 weeks, or whenever it starts smelling.
What you'll need: Ice cubes, coarse salt (kosher or rock salt), lemon or orange peels, dish soap.
Steps:
1. Ice and salt. Drop a handful of ice cubes and 2 tablespoons of coarse salt into the disposal. Run cold water and turn it on for 30 seconds. The ice and salt scour the blades and interior walls, knocking off buildup.
2. Citrus rinse. Cut a lemon or orange into quarters and feed the pieces through the running disposal one at a time. The citric acid deodorizes and the peels help scrub the grinding chamber.
3. Flush with dish soap. Plug the drain, fill the sink with 3–4 inches of warm water, and add a squirt of dish soap. Pull the plug and run the disposal as the soapy water drains. This flushes the entire drain line.
4. Clean the splash guard. That rubber flap at the top? Flip it up and scrub underneath with a toothbrush and dish soap. This is where most disposal odors actually live.
Pro tip: Never pour grease down the disposal. It solidifies and creates blockages that no amount of ice cubes will fix. And despite what the internet says, don't put coffee grounds down there either — they accumulate in pipes over time.
The Toaster and Toaster Oven
How often: Monthly, or when you notice crumbs smoking.
What you'll need: A soft cloth, dish soap, a pastry brush or clean paintbrush, vinegar.
Steps:
1. Unplug it. Always. Let it cool completely.
2. Empty the crumb tray. Pull it out, dump it, wash it with soap and water, dry it completely before reinserting.
3. Shake it out. Hold the toaster upside down over the trash and give it a gentle shake. You'll be horrified by what comes out. That's motivation.
4. Brush the interior. Use a pastry brush or dry toothbrush to loosen crumbs from the heating elements and walls. Never use water inside a toaster.
5. Wipe the exterior. Damp cloth with a drop of dish soap. For stainless steel, wipe in the direction of the grain and dry immediately to prevent water spots.
For toaster ovens: Remove the rack and baking tray, wash them with soap and water. Wipe the interior with a damp cloth (wrung out well). For baked-on grease, a paste of baking soda and water applied for 15 minutes works wonders.
Building It into Your Routine
Cleaning all your appliances at once is a full afternoon project, and that's a recipe for "I'll do it next weekend" indefinitely. Instead, try the one-appliance-per-week approach:
- Microwave (10 minutes)
- Dishwasher (15 minutes of actual work, the rest is cycle time)
- Coffee maker (10 minutes of work, rest is cycle time)
- Oven (15 minutes of work, plus overnight wait)
Rotate through, and every appliance gets deep cleaned once a month without any single session feeling like a chore. If you use something like Cleo to manage your cleaning tasks, this kind of recurring schedule is exactly the sort of thing that works well broken into small steps — a nudge to clean the dishwasher filter is a lot less daunting than "deep clean the kitchen."
Why It Matters Beyond Cleanliness
This isn't just about aesthetics. Dirty appliances work harder, use more energy, and break down faster:
- A clogged dishwasher filter means dishes don't actually get clean, so you're running cycles for nothing.
- Mineral buildup in your coffee maker affects taste and eventually damages the heating element.
- Grease buildup in your oven is a legitimate fire risk.
- A dirty refrigerator coil (pull your fridge out and vacuum the coils on the back or bottom once a year) makes the compressor work overtime, raising your electricity bill.
Taking care of your appliances isn't fussy — it's practical. They last longer, work better, and your kitchen genuinely feels different when everything is running clean.
Fifteen minutes here and there. That's all it takes.
