Your KitchenAid stand mixer is a workhorse. Mine sits on my counter year-round, and I’ve punished it with stiff cookie dough, heavy bread batches, and marathon meringue sessions. If you’ve owned one for any length of time, you already know: eventually, the motor strains.
The head wobbles. A grinding noise creeps in where smooth operation used to live.
That’s the grease talking. Or rather, not talking, because the old grease has broken down, and your mixer is crying for fresh lubrication.
Here’s the thing most people get wrong: greasing a KitchenAid isn’t a factory-only job. You can do it at home. It takes about an hour, some basic tools, and the right lubricant.
No specialist certification required. But you need to do it correctly, because using the wrong grease or skipping critical steps can destroy your mixer’s gears.
I’ve done this procedure more times than I can count. Let me walk you through every single step so your mixer runs like it just came off the assembly line.

Why Your KitchenAid Stand Mixer Needs Regular Greasing
Your KitchenAid is a gear-driven machine. Inside that iconic arched body sits a motor, a worm gear, and a planetary assembly, all coated in grease from the factory. That grease serves two jobs.
First, it lubricates the metal-to-metal contact so gears spin smoothly instead of grinding. Second, it dissipates heat. Without that thermal management, friction builds fast, and friction kills motors.
Over time, the grease degrades. It dries out. It picks up microscopic metal shavings from normal wear.
It separates into a greasy liquid that runs down into the motor housing. When that happens, your mixer starts sounding angry. The head may lock up during heavy mixing.
You might smell burning rubber or hot metal.
I’ve seen people toss perfectly good mixers because they thought the motor was dead. Nine times out of ten, it just needed fresh grease.
The signs are unmistakable. Listen for a whining sound during operation. Feel for excessive vibration.
Notice if the head doesn’t tilt back smoothly. Check if the beater hesitates when hitting a thick patch of dough. Any of those symptoms means it’s time to crack the case open.
What Type of Grease to Use (and What to Never Use)
This is the single most important decision you’ll make during this job. Use the wrong lubricant, and you’ll be buying a new mixer.
The only safe choices are food-grade grease specifically rated for NSF H1 or FDA compliance. That’s non-negotiable. Regular automotive grease, white lithium grease, Vaseline, or cooking oil will fail catastrophically. They’ll break down under heat, melt into the food cavity, or gum up the gears until the motor seizes.
The gold standard is Super Lube 21030 Synthetic Food Grade Grease with PTFE. It’s NSF H1 registered, which means it’s safe for incidental food contact. It stays put at high speeds and doesn’t separate over time.
Many KitchenAid repair shops use it exclusively.
You can also buy KitchenAid’s own grease. It comes in a small tube and costs more per ounce, but it’s formulated specifically for these mixers. I’ve used both.
The Super Lube works just as well and costs less.
What to absolutely avoid:
- WD-40 (it’s a solvent, not a lubricant)
- Vegetable oil or shortening (they go rancid and attract bacteria)
- Silicone spray (too thin, won’t stay on gears)
- Lithium grease (too thick, creates drag)
- Any lubricant not labeled food-grade
I cannot stress this enough. Using the wrong grease is the fastest way to kill your KitchenAid. The gears are brass and steel, and they need specific viscosity.
Get it right from the start.
For more on what qualifies as food-grade lubricant and why it matters, the NSF International website offers detailed guidance on H1 registration standards.
Tools and Supplies You’ll Need
Before you start, gather everything. Nothing kills momentum like hunting for a missing screwdriver mid-disassembly.
You’ll need:
- Food-grade grease (Super Lube or KitchenAid brand)
- Phillips head screwdriver (medium size)
- Flathead screwdriver (small, for prying)
- 3/8-inch nut driver or socket wrench
- 5/16-inch nut driver or socket wrench
- Small putty knife or plastic scraper
- Clean rags or paper towels
- Bowl or tray for small parts
- Permanent marker (for labeling screws)
- Latex or nitrile gloves
- Flashlight or headlamp
Optional but helpful:
- Dental pick or small wire brush (for cleaning old grease out of crevices)
- Torque wrench (if you’re a perfectionist about reassembly)
- Camera or phone (take photos at each stage for reference)
Your workspace matters too. Pick a clean, well-lit spot. A kitchen island works great, but protect the surface with a towel or cardboard.
You’ll be dealing with messy old grease, and it stains.
Step-by-Step: How to Grease a KitchenAid Stand Mixer
I’ll use the classic Artisan tilt-head model for this guide. The procedure for Professional bowl-lift models is similar, but I’ll note key differences where they appear.
Step 1: Unplug the Mixer
Seriously. Unplug it. I know you know this, but I’ve met too many people who skip it.
You’re working near electrical components. The switch could get bumped. Remove the power cord from the wall completely.
Step 2: Remove the Attachments and Bowl
Take off the flat beater, dough hook, and wire whip. Lift the bowl off the base. Set everything aside.
You don’t want attachments dangling while you’re working on the head.
Step 3: Tilt the Head Back and Lock It
If you have a tilt-head model, tilt the head back into its locked position. This gives you access to the screws on the back of the neck. For bowl-lift models, raise the bowl platform to its highest position and lock it.
Step 4: Remove the Top Cover
On tilt-head models, you’ll see a large screw on the top center of the mixer’s neck. Use your 3/8-inch nut driver to remove it. There are also two screws at the back of the head, one on each side of the hinge.
Remove those too.
On Professional models, the cover is held by screws along the top and back. Remove all of them.
Once the screws are out, lift the top cover straight up. It may be stuck from years of grease residue. Gently tap it with the handle of your screwdriver if needed.
Don’t pry hard or you’ll crack the plastic.
Set the cover aside with its screws. I tape each screw to its corresponding hole location on a piece of cardboard. It saves headaches during reassembly.
Step 5: Inspect the Interior
Now you’re looking at the guts. You’ll see the planetary assembly, the metal housing that drives the attachments. Around it, there’s old grease.
It might be yellowish, brownish, or even greenish depending on age and heat exposure. It should be thick and paste-like, not runny.
Runny grease is bad news. It means the lubricant has broken down and may have leaked into the motor windings.
Shine your flashlight around. Look for metal shavings in the grease. A few tiny flecks are normal.
Large chunks or a gritty texture mean a gear is wearing out and needs replacement, not just regreasing.
Step 6: Remove the Planetary Assembly
This step varies slightly by model, but the general approach is the same.
On tilt-head models, look at the top of the planetary housing. You’ll see a retaining ring or snap ring holding it in place. Use a flathead screwdriver to carefully pry the ring off.
Catch it, they fly.
With the ring removed, grasp the planetary assembly firmly and pull it straight up. It may resist. Rock it gently side to side while pulling.
It’s a tight fit.
On Professional models, you need to remove the motor housing first. That’s more complex. For this guide, I’ll assume you’re tackling a tilt-head.
Set the planetary assembly on your work surface. Don’t set it down on the gear side, the teeth are soft brass and can bend.
Step 7: Clean Out the Old Grease
This is the messy part. Get your gloves on.
Start scraping the old grease out of the mixer body. Use your putty knife or plastic scraper. Get into every crevice, especially around the main drive gear and the bearing surfaces.
Work the old grease out of the planetary assembly too. Pay attention to the gear teeth and the internal bore where the attachment shaft rides.
Don’t try to get it 100% clean. A thin residue is fine, it’s going to mix with the new grease anyway. But you want to remove all the big clumps and any grease that’s discolored or gritty.
Use your rags to wipe down the interior surfaces. If the old grease is caked on hard, a dental pick helps scrape it out of tight spots.
Do not use solvents. No degreaser, no alcohol, no acetone. Solvents can attack the plastic components inside the mixer and will definitely strip residual lubrication from bearing surfaces that need it. Mechanical scraping only.
Step 8: Apply Fresh Grease
Now for the rewarding part.
Take your tube of food-grade grease. You’ll need about a tablespoon total, maybe two for larger mixers. Don’t overdo it.
Too much grease creates drag, builds heat, and can ooze out into your food.
Start with the planetary assembly. Smear a thin, even layer of grease onto all the gear teeth, both the large ring gear and the smaller pinion gears. Work it into the tooth spaces with your finger.
Coat the outer bearing surfaces too.
Now grease the inside of the mixer body. Focus on the main drive gear (the big one at the top that mates with the planetary). Coat its teeth the same way.
Also apply a thin layer to the bearing surfaces where the planetary assembly seats.
Finally, grease the shaft that the attachment hub rides on. This is the vertical shaft inside the planetary housing. A light coat is all it needs.
Step 9: Reinstall the Planetary Assembly
Line up the planetary assembly with the drive gear inside the mixer body. The teeth should mesh smoothly. Lower it into place.
It should seat firmly without resistance.
If it fights you, don’t force it. Pull it back out and check that the gears are aligned. You may have missed a spot of old grease that’s preventing a clean seat.
Once seated, reinstall the retaining ring. Press it into its groove until it’s fully seated. You’ll hear it snap.
Give it a light tug to verify it’s locked.
Step 10: Replace the Top Cover
Put the top cover back on. Align it carefully so it sits flush against the mixer body. There are alignment tabs, make sure they slot into their receptacles.
Reinstall the screws. Tighten them in a crisscross pattern to ensure even pressure. Don’t overtighten.
You’re threading into plastic, and stripping those holes is a nightmare. Snug is enough.
Step 11: Test Before Reassembling Fully
Plug the mixer back in, briefly. Turn it on to the lowest speed. Listen.
It should hum smoothly. If you hear grinding, clicking, or scraping, stop immediately. Something isn’t seated right.
Run it for about ten seconds. Then turn it off and unplug it. Feel the top cover for excessive heat.
It should be cool or barely warm.
If everything sounds and feels good, you’re done.
Step 12: Wipe Down the Exterior
Grease always finds its way onto the outside of the mixer during this job. Use a damp cloth to clean the top cover and any smudges. Then reinstall the bowl and attachments.
Common Mistakes That Ruin the Job
I’ve fixed mixers that were botched by well-meaning owners. Here’s what goes wrong most often:
Using too much grease. More is not better. Extra grease doesn’t improve lubrication, it just gets hot and drips down into the food. A thin, even coating is all the gears need.
Skipping the planetary assembly cleaning. If you only clean the mixer body and not the planetary, old gritty grease stays in the system. It contaminates the new grease and accelerates wear.
Forgetting the retaining ring. This is embarrassingly common. Someone reassembles the mixer, turns it on, and the planetary assembly flies upward into the cover. That usually cracks the cover and damages the gears.
Overtightening screws. The plastic threads strip easily. If a screw spins without tightening, you’ve stripped the hole. That means a new top cover or a repair kit.
Using non-food-grade grease. I covered this already, but it bears repeating. Automotive grease contains additives that are toxic if they migrate into your food. They also don’t handle the heat profile of a mixer.
Not testing before full reassembly. If something is wrong, you want to catch it when the cover is easy to remove, not after you’ve reinstalled the bowl and attachments and everything is buttoned up.
How Often Should You Grease Your KitchenAid?
This depends entirely on how hard you use the mixer.
For a home baker who makes cookies and cakes a few times a week: every 12 to 18 months is fine. Mark your calendar. Do it when you change your smoke detector batteries.
For heavy users, weekly bread bakers, small business operators, or anyone who runs the mixer for extended periods, shorten that to every 6 to 9 months. The grease breaks down faster under sustained load.
For occasional users who pull the mixer out for holidays only: every 2 to 3 years is adequate. But check it annually. If the mixer has been sitting for years, the grease can separate and harden anyway.
A good rule of thumb: if you hear the mixer start making sounds it didn’t make when new, grease it. Don’t wait.
Frequently Asked Questions
Can I use vegetable oil in a pinch?
No. Never. Vegetable oil goes rancid, attracts pests, and provides almost no lubrication under load.
It will damage your mixer.
My mixer is making a grinding noise. Is it too late?
Not necessarily. Grinding often means the grease is gone and metal is rubbing metal. Stop using the mixer immediately.
Open it up. If the gears aren’t visibly damaged, fresh grease may solve the problem. If there’s already wear, you’ll need replacement gears.
What about the motor brushes?
Greasing doesn’t address the motor brushes. If your mixer sparks or runs erratically, the brushes may be worn. That’s a separate repair.
Grease keeps the gears happy, not the motor internals.
Do Professional models need different grease?
No. The same food-grade grease works for any KitchenAid stand mixer. The procedure differs slightly (more screws, more components to remove), but the lubricant is identical.
Can I pay someone to do this?
Absolutely. Small appliance repair shops charge around $80 to $150 for this job. But it’s a straightforward DIY project that saves you money and teaches you how your mixer works.
Why is my mixer leaking oil after greasing?
You used too much grease. The excess heats up, thins out, and runs down through the attachment hub. Wipe away what you can, and next time use less.
That’s the full process. Your KitchenAid will run quieter, cooler, and longer. It’s one of those maintenance tasks that most owners never do, which means a properly greased mixer stands out.
It lasts decades instead of years.
The tools cost less than a single repair visit. The grease costs less than a latte. And the satisfaction of hearing your mixer purr after you’ve brought it back to life?
That’s priceless.
So grab your tools, open your mixer, and give those gears what they need. Your KitchenAid deserves it. And so does your next batch of bread dough.
