Learning how to clean a blender the right way is less about scrubbing harder and more about knowing which parts actually need attention, and which ones will punish you later if you skip them.
We used to just rinse ours and call it done, until the day a smoothie came out tasting faintly like the garlic hummus we had made two nights earlier.
That was the moment we started actually taking the gasket apart instead of leaving it in place out of laziness.
If a worn seal or gasket is already part of your blender troubles, Why Is My Blender Leaking? covers that same part from a different angle, and Can a Blender Make Nut Butter and Other Thick Foods? explains why thick, oily blends leave behind more residue than a quick rinse can handle.
Getting to the Blade Without Cutting Yourself
Figuring out how to clean under the blender blades safely depends heavily on whether your model has a removable blade assembly at all.
For models with a removable assembly, the safest approach is letting the blender do the work itself like filling the jar partway with warm, soapy water and running it for thirty to sixty seconds rather than reaching in with a sponge near the blades.
KitchenAid K400 Variable Speed Blender, 56 oz
Its fixed blade design genuinely simplifies this whole step. There’s no separate assembly to unscrew, remove, or worry about handling carefully near sharp edges.

Why Does My Blender Still Smell After Washing It?
If a rinse and wash haven’t solved it and you are asking why does my blender still smell after washing usually points to one specific hiding spot.
That’s the rubber gasket, or the underside of the blade assembly, both of which trap food particles and moisture in places a quick surface wipe never reaches.
Disassemble both parts fully, soak them in a vinegar and water solution for about thirty minutes, scrub gently, rinse, and let everything dry completely before reassembling.
A gasket that keeps smelling even after this treatment has likely absorbed odor into the rubber itself and is worth simply replacing.
Vitamix Propel Series 750 Professional-Grade Blender, 64 oz
Its removable gasket makes this deep clean genuinely manageable. It’s easy to pull it out for a proper soak every few weeks rather than waiting for a smell to force the issue.

Why Does My Blender Jar Turn Cloudy?
A jar that’s lost its clarity over time usually traces back to either oily food residue building up gradually or repeated exposure to high dishwasher heat etching the plastic’s surface.
A baking soda paste works into the interior with a long-handled brush. Leave it to sit for about an hour, then rinse it clean. This handles most of the cloudiness caused by residue.
Etching from heat damage, on the other hand, is permanent and won’t scrub away no matter how aggressively you try.
Ninja Detect Blender with Cups, BlendSense Tech, 72oz
Its included to-go cups have held up clearer over time since we started hand washing them instead of running everything through repeated high-heat dishwasher cycles.

Can You Put The Blender Jar In The Dishwasher?
This depends on the specific model and material. Check your manual before assuming it is worth the extra minute.
Many jars are dishwasher safe on the top rack, but daily use at high heat can gradually etch the plastic and dull or corrode metal blades over time.
That is exactly why hand washing, even for parts labeled dishwasher safe, tends to keep a blender looking and performing better for longer.
Breville BBL620DBL Fresh and Furious Blender
Its auto-clean functionality handles the bulk of daily maintenance well. Make sure to hand wash the jar occasionally just to avoid the gradual clouding repeated dishwasher cycles can cause.

Frequently Asked Questions
How do you clean a blender properly?
Rinse and wash after every use, deep clean every four to five uses with baking soda or vinegar, and fully disassemble the gasket and blade area periodically rather than just wiping the jar’s interior.
How do you clean under the blender blades?
If the blade assembly is removable, soak it separately. If it’s fixed to the pitcher, run warm soapy water through the blender itself rather than reaching in by hand.
Why does my blender still smell after washing?
Usually the rubber gasket or the underside of the blade assembly, both of which trap residue and moisture a surface rinse doesn’t reach. A vinegar soak or gasket replacement usually resolves it.
Why does my blender jar turn cloudy?
It’s either because of oily residue buildup, fixable with a baking soda scrub, or heat etching from repeated dishwasher cycles, which is permanent damage to the plastic surface.
Can you put the blender jar in the dishwasher?
It depends on the model and material, so check your manual. Even dishwasher-safe parts often last longer with hand washing instead of daily high-heat cycles.
Conclusion
A genuinely clean blender comes down to a few consistent habits, a quick rinse after every use, an occasional deeper clean of the gasket and blade area, and knowing when hand washing beats the dishwasher for keeping the jar clear and odor-free over time.
