The easiest way to keep your stand mixer performing like new is to wipe it down after every use, avoid submerging the head, and lubricate the gears annually. A few minutes of regular care prevents common issues like wobbling, noisy operation, and stripped gears.
Stand mixer maintenance boils down to cleaning, lubrication, and proper use. Here are the key facts:
- Cleaning Frequency: Wipe the exterior and attachments after each use. Deep-clean the bowl and dough hook weekly if used often.
- Lubrication Schedule: Apply food-grade grease to the gears every 12 months or after 100 hours of heavy use.
- Attachment Care: Hand-wash attachments with warm soapy water and dry immediately. Never put them in the dishwasher.
- Motor Protection: Never run the mixer above speed 2 when kneading stiff dough to prevent overheating.
Daily and Weekly Cleaning
After each use, unplug the mixer and wipe the body with a damp cloth. Pay special attention to the vent slots where flour can accumulate. For the bowl and attachments, wash them in warm soapy water, rinse, and dry thoroughly. The bowl can go in the dishwasher, but attachments like the paddle, whisk, and dough hook should be hand-washed to preserve their coating.
Once a week, remove the bowl and tilt the head back to clean the attachment hub and the area around the shaft. Use a soft brush or toothpick to dislodge any dried dough or grease. Check the hinge pin for debris; a buildup here can cause the head to not lock properly.
How to Lubricate the Gears
Stand mixer gears require food-grade grease (not regular oil) to reduce friction. You’ll need a tube of NSF-certified grease and a small brush or spatula. Start by unplugging the mixer and removing the attachments. Tilt the head back and locate the gear housing (usually a metal or plastic cover on top).
- Remove the screws securing the gear housing cover (refer to your manual for screw locations).
- Carefully lift off the cover to expose the gears. Note the existing grease color and consistency.
- Using a brush, wipe away old, dirty grease and apply a pea-sized amount of fresh grease to each gear tooth. Do not overfill.
- Reattach the cover and screws, then run the mixer on speed 1 for 30 seconds to distribute the grease.
For most home bakers, annual lubrication is sufficient. If you hear grinding or whining noises, lubricate sooner.
Checking and Replacing the Motor Brushes
Many stand mixers have carbon brushes that wear down over time. When they are too short, the motor may run erratically or stop. Check the brushes every 2 years or if you notice sparking or intermittent power.
Locate the brush caps on the sides of the motor housing (usually marked with a small arrow). Unplug the mixer, unscrew the caps, and pull out the springs and brushes. If the brush is shorter than 1/4 inch, replace it with the exact model specified in your manual. Insert the new brush, replace the spring and cap, and repeat on the other side. Run the mixer for 10 minutes on speed 4 to seat the brushes.
Adjusting the Beater-to-Bowl Clearance
Over time, the beater may no longer scrape the bottom and sides of the bowl, leading to uneven mixing. The fix is a simple adjustment. For most tilt-head mixers, locate the flathead screw near the hinge (often under a plastic cover).
- Attach the flat beater and lower the head.
- Insert a dime between the beater and the bowl. If the dime passes with slight resistance, clearance is correct.
- If too tight or too loose, turn the adjustment screw clockwise to raise the beater or counterclockwise to lower it. Test with a dime each time.
For bowl-lift models, the adjustment screw is usually on the arm or under the bowl support. Refer to your manual for specifics. Proper clearance prevents bowl wear and ensures thorough mixing.
Storing Your Stand Mixer Properly
Store your mixer in a dry, cool place away from direct sunlight and heat sources. If you keep it on the counter, use a fitted cover to protect against dust and grease. Never store the mixer with the head tilted or with attachments attached, as this can strain the hinge and motor bearings.
If you need to store it for months, remove the bowl and attachments, clean everything, and wrap the cord loosely around the base. Place a sheet of wax paper between the bowl and the mixer base to prevent metal-on-metal contact. Avoid stacking items on top of the mixer.
Pro Tips
- Run the mixer on speed 1 for 30 seconds after lubricating to distribute grease evenly.
- Use a dime as a feeler gauge to check beater-to-bowl clearance quickly.
- Mark your calendar for annual lubrication using a phone reminder or sticker on the mixer base.
- Keep a spare set of carbon brushes on hand so you can replace them immediately when needed.
Common Mistakes to Avoid
- Submerging the mixer head in water or running it through the dishwasher will ruin the motor and electronics.
- Using WD-40 or standard oil on gears will attract dust and cause premature wear; always use food-grade grease.
- Ignoring a wobbling mixer can lead to permanent damage; check the bowl lock and hinge pin first.
- Running the mixer at high speed for heavy doughs (like bagel dough) can overheat the motor; use speed 2 max.
FAQ
Can I put my stand mixer bowl in the dishwasher?
Yes, most stainless steel bowls are dishwasher safe. However, the bowl’s coating may dull over time. Hand washing is gentler and recommended for non-stick bowls.
How often should I lubricate my KitchenAid stand mixer?
KitchenAid recommends lubricating the gears every 12 months for home use. If you bake heavily (multiple times a week), do it every 6 months.
Why is my stand mixer making a grinding noise?
A grinding noise usually indicates dry gears or worn carbon brushes. First, try lubricating the gears. If the noise persists, check the brushes and replace them if short.
The Bottom Line
With routine care, a quality stand mixer can last decades. Clean it after every use, grease the gears annually, adjust clearance when needed, and store it properly. These simple steps will keep your mixer running smoothly for all your baking projects.
