TL;DR
Unplug the mixer, eject the beaters, and wash them within a few minutes while the batter is still soft. The slots the beaters lock into are the part that gets neglected, and they are cleaned with a dry brush and a barely damp cotton swab, never by running water into the housing.
Where the Batter Actually Goes
A hand mixer flings batter upward. Some of it lands on the underside of the housing, some runs down the beater shanks, and a little works its way into the ejection slots where the beaters lock in.
That last part is the problem. The slots open directly into the housing, and the housing contains the motor, the gears, and the speed switch. Batter that dries in there hardens around the drive sockets and eventually makes the beaters hard to seat or hard to release.
Because there is no way to flush it out safely, the answer is to prevent buildup rather than to clean it deeply later. The general rule about powered housings appears across the guide to cleaning small kitchen appliances safely.
How Do You Clean a Hand Mixer?
Unplug it, press the eject button, and put the beaters straight into hot soapy water. Wipe the underside of the housing and the beater shanks with a damp cloth, then dry. Brush the ejection slots with a dry pastry brush or a soft toothbrush and finish with a barely damp cotton swab around each opening.
Total time is about two minutes. The mixer never goes near a tap.
Cleaning the Ejection Slots Properly
Turn the mixer upside down so gravity works with you and debris falls out rather than in. Push a dry soft-bristle brush into each slot and rotate it, then tap the mixer against your palm to shake the crumbs loose.
For dried batter around the rim of a slot, wrap a cotton swab lightly damp with warm soapy water and work only the visible edge. Follow with a dry swab immediately. The rule is that nothing wet should be able to run downward into the housing.
A wooden toothpick clears a compacted line of dried batter without scratching. Do not use anything metal, and do not try to pry.
Why You Cannot Just Rinse It
The housing is not sealed. Water entering the slots reaches the gears and the motor windings, and it does not evaporate out. The result is corrosion, a stiff eject mechanism, or a mixer that trips a breaker.
Some models have a fully sealed lower housing and even allow the beater area to be rinsed. That is unusual, and only the manual can tell you. Assume yours is not sealed unless it says otherwise. Source: appliance manufacturer use and care manuals
Washing the Beaters and Attachments
Most modern beaters are stainless and dishwasher safe on the top rack. Check the manual, since some sets have a coating that dulls in a dishwasher, and older aluminum beaters darken permanently from dishwasher detergent.
Wire beaters and dough hooks trap batter in the joins. Soak them right away and use a narrow brush pushed through from the inside rather than trying to wipe between the wires.
Never use chlorine bleach on stainless beaters. Chloride pits stainless steel and leaves permanent rust spots.
Caring for the Housing, Cord, and Switch
Wipe the body with a cloth dampened in warm soapy water and dry it right away. Give attention to the speed switch track and the seam where the two housing halves meet, both of which collect flour. Brush those dry first.
On a printed control panel, skip ammonia-based glass cleaner and rubbing alcohol, since both lift markings. On a painted body, avoid abrasive pads, which burnish the finish.
Store the mixer with the cord loosely coiled rather than wrapped tightly around the housing, which stresses the cord where it enters the body. Store the beaters separately so they do not sit in the slots collecting dust.
How Often Should This Happen?
Wash the beaters and wipe the housing after every use. Brush the ejection slots at the same time, since ten seconds then prevents a job later. Do a fuller wipe of the switch track and housing seam monthly.
Wipe between sweet and savory batches too. Dried batter left on a beater shank is a straightforward way for one recipe's flavor to reach the next.

FAQ
How do you clean batter out of hand mixer beater slots?
Unplug the mixer, turn it upside down so debris falls out, and work a dry soft-bristle brush into each slot. Tap the mixer against your palm to shake crumbs free, then wipe the visible rim with a barely damp cotton swab and follow with a dry one.
Can you rinse a hand mixer?
No, unless the manual explicitly says the lower housing is sealed and rinsable, which is uncommon. Water entering the ejection slots reaches the gears and motor windings and does not evaporate out. Wipe the housing with a damp cloth and dry it immediately instead.
Are hand mixer beaters dishwasher safe?
Most modern stainless beaters are top-rack dishwasher safe, but check the manual. Some coated beaters dull in a dishwasher, and older aluminum beaters darken permanently from dishwasher detergent. Hand washing in hot soapy water right after use is always safe.
Why are my beaters hard to insert or eject?
Dried batter is usually packed around the drive sockets inside the ejection slots. Unplug the mixer, brush the slots dry, and clear compacted residue with a wooden toothpick. Avoid metal tools and never pry. If the mechanism still binds, have the mixer serviced.
How do I clean the underside of a hand mixer housing?
Wipe it with a cloth dampened in warm soapy water while holding the mixer at an angle so nothing runs toward the slots, then dry it. Brush flour out of the housing seam dry before adding any moisture, and finish with a clean dry cloth.
Can I use bleach to clean hand mixer beaters?
No. Chloride bleach pits stainless steel and leaves permanent rust spots. Hot soapy water handles batter, and a baking soda paste handles stubborn staining. Bleach also has no advantage here, since batter residue is organic and responds well to detergent.
How should I store a hand mixer?
Store the beaters out of the slots so nothing sits in the openings collecting dust, and coil the cord loosely rather than wrapping it tightly around the housing, which stresses the cord at the entry point. Keep the whole unit dry and out of a humid cabinet.
