How to Clean an Immersion Blender Safely

By Boxofin Editorial Team • 7 October 2026

Many people drop the whole immersion blender into a sink of soapy water, motor and all. That is the fastest way to damage it. Unplug the blender, detach the shaft if your model allows it, and wash the shaft and blade guard in warm soapy water. Wipe the motor housing with a damp cloth and keep it dry.

Quick answer

Unplug it, remove the shaft, and wash the shaft and blades by hand with warm water and dish soap. Never dunk the motor housing. For a fast clean after soup, blend warm soapy water briefly in a tall container, then rinse.

  • Best for light residue: the soapy-water blend, then a rinse
  • Best for dried food: detach the shaft and hand-wash
Key Takeaways
  • Always unplug the blender before you clean it.
  • Only the detachable shaft goes in water. The motor housing gets a damp cloth.
  • Rinse right after use so food does not dry on the blades.
  • Dishwasher rules differ by model. Check your manual.
  • Dry the shaft fully before you store it.
Note on Scope: This guide covers cleaning after soups, sauces, and smoothies, with extra detail for Cuisinart models. It does not cover repairs or replacing blades. Your model’s manual always wins over general advice.

What to do before you clean

Turn the blender off and unplug it first. Cuisinart tells users to do this before assembling, disassembling, or cleaning. A plugged-in blender can start by accident while your fingers are near the blades.

Treat the blades as sharp at all times. Cuisinart warns that immersion-blender blades should be handled carefully during removal, insertion, and cleaning.

How do I clean an immersion blender after using it?

Follow five steps: unplug, detach, rinse, wash, dry. Cuisinart recommends rinsing wetted parts right away so food does not dry on them.

  1. Unplug the blender.
  2. Detach the shaft from the motor housing, if your model allows it.
  3. Rinse the shaft under warm running water. Point the blade end down.
  4. Wash with warm water and mild dish soap. Use a long-handled brush or sponge.
  5. Dry with a towel, then air-dry upside down.

Cuisinart advises removing the detachable shaft before washing the shaft or blades. This keeps water away from the motor.

Can I clean an immersion blender by blending soapy water?

Yes, for light residue. It is a good first pass after soup, sauce, or a smoothie. It does not replace a proper wash when food is stuck or dried.

Cuisinart’s manual describes a blade-assembly method: warm water with dishwashing liquid, run on low for 15 seconds, then repeat with clean water.

Expert Insight: Use a tall, narrow container. A wide bowl lets water splash up toward the motor housing. Keep the water level below where the shaft meets the motor.

Worked example

  1. Pour warm water into a tall jar or measuring cup, about halfway.
  2. Add a small squirt of dish soap. A lot of soap makes too much foam.
  3. Lower the blade end in. Keep the motor housing well above the water.
  4. Run on low for about 15 seconds.
  5. Unplug it. Pour out the soapy water.
  6. Repeat with clean warm water. Then dry.

How do I clean immersion blender blades without cutting myself?

Never wipe the blades with your fingers. Use a long-handled bottle brush or a soft brush, and always unplug first.

  • Hold the shaft by the top, with the blades pointing away from you.
  • Brush from the shaft side toward the open edge of the guard, not across the blade edge.
  • Wear a thin cut-resistant glove if your blades are fixed and hard to reach.
  • Never leave the blender in a sink full of soapy water. You cannot see the blades.

How do I remove dried food from around the blade guard?

Soak the shaft end in warm soapy water for 10 to 15 minutes, then brush it. Soaking softens dried food so you do not need to scrub hard near the blades.

Use a tall glass, and keep only the guard end underwater. Then use a narrow brush to reach under the guard. A wooden toothpick can lift stubborn bits, but keep your fingers clear. Rinse until the water runs clear.

Can I submerge the motor housing in water?

No. Clean the motor housing only with a sponge or damp cloth. Cuisinart’s instructions say it must not be immersed in water.

Wipe the buttons and seams, then dry with a clean towel. Do not hold the housing under the faucet.

How do I clean a Cuisinart immersion blender?

Unplug it, twist off the shaft, and hand-wash the shaft with hot water and mild detergent. Wipe the motor with a damp cloth. For the CSB175, Cuisinart says to hand-wash the blending shaft and not use a dishwasher. See the Cuisinart CSB175 instruction booklet for details.

Other Cuisinart models differ. The Cuisinart Power Blend manual is one example of a separate booklet with its own steps.

If your manual says hand-wash only, then wash by hand every time.

If your manual lists a part as top-rack safe, then place it on the top rack only.

If you lost the manual, then hand-wash. It is the safe default.

Can I put an immersion blender shaft in the dishwasher?

Only if your manual says so. Some Cuisinart manuals allow top-rack washing for detachable parts, while the CSB175 shaft is hand-wash only. Use this table as a guide, not a replacement for your manual.

PartCleaning guidance
Motor housingDamp cloth only. Never submerge or put in a dishwasher.
Blending shaftHand-wash on models like the CSB175. Check the manual for others.
Whisk attachmentCheck the manual. Some are top-rack safe.
Beaker or cupCheck the manual. Often top-rack safe.
Chopper bowl and lidCheck the manual. Often top-rack safe.

How should I clean it after making hot soup?

Turn it off, lift it out, and let it drip over the pot. Unplug it, then rinse the shaft once it is safe to touch. Do not let soup dry on the shaft while you eat.

Hot liquid can burn, and starchy or fatty soup turns hard fast. A quick warm rinse right away saves scrubbing later.

How do I dry and store an immersion blender safely?

Dry the shaft with a towel, then let it air-dry with the blade end pointing down so water can drain. Store it only when no water is left inside the guard.

  • Keep the motor housing and shaft apart if your model detaches.
  • Store blades where fingers will not touch them, such as in a drawer slot or a covered holder.
  • Sniff the shaft before storing. A sour smell means food is still trapped.

Common cleaning mistakes

  • Submerging the motor housing.
  • Cleaning while the blender is plugged in.
  • Rinsing only briefly and leaving food inside the guard.
  • Assuming every shaft is dishwasher-safe.
  • Using a sponge with bare fingers near the blades.
  • Putting the blender away damp.

Troubleshooting

ProblemWhat to do
Dried foodSoak the shaft end in warm soapy water, then brush.
OdorWash again and check under the guard. Dry fully.
