Here’s how to clean a blender in about a minute: fill the jar halfway with warm water, add a drop of dish soap, blend for 30 seconds, then rinse. That handles everyday cleanup. Every week or so, take the jar apart if your model allows it and wash the blade assembly and rubber gasket separately, because that’s where smoothie residue and smells hide.

Most people just rinse the jar and call it done. Then one day the blender smells a bit sour, and the culprit is a thin layer of old smoothie under the blades.
How to clean a blender: the quick everyday method
Clean it right after you use it. Fresh residue comes off in seconds; dried-on banana and protein powder take real scrubbing.
- Rinse out the leftovers with warm water.
- Fill halfway with warm water and add one or two drops of dish soap. Too much soap overflows.
- Blend for 30 to 60 seconds with the lid on, starting low and turning it up.
- Rinse and air-dry upside down.
Many high-performance brands, such as Vitamix, recommend this same soap-and-water blend as the main cleaning method for their containers.
How to clean a blender deeply (gasket and blades)
If your jar has a removable base, take it apart about once a week:
- Unplug the motor base before touching any blades.
- Unscrew the base ring and lift out the blade assembly and rubber gasket carefully.
- Wash the parts by hand in warm, soapy water. Use a bottle brush or old toothbrush around the blades instead of your fingers.
- Clean the gasket both sides; it traps the most residue and causes most smells.
- Dry everything completely before reassembling so no water gets trapped.
Fixing common blender cleaning problems
| Problem | Likely cause | Fix |
|---|---|---|
| — | — | — |
| Sour or musty smell | Residue under the blades or in the gasket | Take apart and wash the gasket |
| Cloudy film on the jar | Hard water minerals | Soak or blend with diluted white vinegar, then rinse |
| Stuck-on residue | Left to dry | Blend warm water and a spoonful of baking soda |
| Garlic or onion smell | Strong flavors absorbed | Blend water with lemon juice or baking soda |
| Stained plastic jar | Turmeric, berries, greens | Baking soda paste, then sunlight to fade stains |
Don’t forget the motor base
The base gets splashes and sticky fingerprints too. Unplug it and wipe it with a damp, soapy cloth, then dry it. Use a cotton swab around the buttons and the coupling where the jar sits. Never submerge the base or pour water over it; it holds the motor and electronics.

A few habits that keep it cleaner
Clean it right away, don’t leave smoothies sitting in the jar, and add liquids first when you blend so less sticks to the bottom. If you blend lots of greens or protein shakes, do the deep clean of the gasket more often, around every few days.
Quick FAQ
Can you put a blender in the dishwasher? Many jars are top-rack dishwasher safe, but some blade assemblies and high-end containers are hand-wash only, so check the manual. How do I get the smell out of my blender gasket? Remove it, wash it in warm soapy water, soak it briefly in diluted vinegar if needed, and dry it fully. Is it safe to clean blender blades with my hands? It’s safer to use a brush; blades are sharp even when the blender is unplugged.
How to clean a blender: a quick recap
- Every use: warm water, a drop of soap, blend 30 seconds and rinse.
- Weekly: take apart and wash the blade assembly and gasket.
- Extras: vinegar for cloudy film, baking soda for smells and stuck residue.
