How to Clean a Blender Properly: 30-Second Blitz + Deep Clean Guide

Most people clean their blender in exactly two ways: a quick rinse and a prayer, or a full sink-scrub production that makes you avoid smoothies for a week. Both are wrong. Every major blender manufacturer — Vitamix, Blendtec, KitchenAid, NutriBullet — designs their machines to be cleaned in under a minute with the blender itself doing the work, plus a periodic deep clean that takes about ten minutes of actual attention.

Here’s the complete system: the after-every-use blitz, the deep hand-wash, the blade-and-gasket care nobody does, the cloudy-jar fix that actually works, and the one cleaning mistake that can void your warranty.

Blender Cleaning Schedule at a Glance

Task	How often	Time
Rinse immediately after pouring	Every use	15 seconds
Soap-and-water self-clean blitz	Every use	30–60 seconds
Deep hand-wash (blades, gasket, lid seal)	Weekly if you blend often	10 minutes
Motor base wipe-down	Every use / as needed	30 seconds
Cloudy-jar or odor treatment	As needed	5 min active + soak

Why “Rinse and Pray” Ruins Blenders

Residue becomes dramatically harder to remove once it dries onto the sides and around the blades — NutriBullet calls the immediate rinse the step that “matters more than people realize” NutriBullet. Dried smoothie under the blades, oil film from nut butters, and garlic smells that survive three rinses are all symptoms of the same thing: residue that was never washed off in time. The fix is a habit, not effort.

What You’ll Need

• Dish soap (literally 1–3 drops — more on that below)
• Warm water
• A soft sponge or cloth (never steel wool or stiff brushes)
• White vinegar and baking soda (for odors and deep cleans)
• Powdered dishwasher detergent (the secret weapon for cloudy jars)
• A clean, dry cloth for the motor base

Step 1: The 30-Second Self-Clean Blitz (After Every Use)

This is the method all four manufacturers officially recommend, and it’s almost identical across brands:

1. Rinse the jar immediately after pouring your drink
2. Add warm water halfway and 1–3 drops of dish soap — Vitamix’s official instructions are “a few drops of dish soap, fill halfway with warm water” Vitamix; KitchenAid says 1–2 drops KitchenAid; Blendtec specifies exactly 1 cup (240 ml) of hot water and one drop Blendtec
3. Blend on high for 30–60 seconds (Vitamix, NutriBullet) or pulse for just 5 seconds (Blendtec) — or hit the Clean cycle if your model has one. KitchenAid’s version runs 15–20 seconds KitchenAid
4. Dump, rinse well, done

The spinning soapy water creates a vortex that scrubs the sides, the corners, and under the blades — no sponge required NutriBullet. Resist adding more soap: excess detergent means a foam party in your kitchen and five extra rinse cycles.

⚠️ Portable-blender warning: NutriBullet cautions that personal cups with sealed blades should only ever be cleaned with room-temperature or cold water and a single drop of soap — blending warm liquids in a sealed cup builds steam pressure that can force the cup and blade apart NutriBullet

Step 2: The Deep Hand-Wash (Once a Week)

For nut butters, oily dressings, curries, and anything spiced, the blitz isn’t enough. NutriBullet recommends a deeper hand-wash every few uses — at minimum weekly for regular blender users NutriBullet

1. Unplug the blender first. Non-negotiable before handling blades or disassembling anything NutriBullet
2. Disassemble: jar off the base, lid off, blade assembly off (if yours unscrews)
3. Soak in diluted vinegar — water plus a small amount of white vinegar for 10–15 minutes loosens stuck residue and neutralizes odors NutriBullet
4. Scrub with a soft sponge and dish soap — inside the jar, around the blades, along the lid gasket. Skip steel wool, wire brushes, and harsh scouring pads; they scratch plastic and glass and damage blade finishes NutriBullet
5. Rinse everything thoroughly — leftover soap or vinegar will flavor your next smoothie
6. Air-dry completely before reassembling. Reassembling damp traps moisture and breeds mildew and odor NutriBullet

Step 3: Show the Blades, Gasket & Lid Seal Some Love

These three hidden zones are where “my blender smells weird” comes from.

Under the blades

That residue in the photo is what hides under the blade assembly after “quick rinse” cleaning. KitchenAid’s advice: the most effective blade cleaning is either letting the soapy-water blitz do the work, or carefully removing the blades and soaking them KitchenAid. If your blade assembly unscrews, take it apart weekly; if it’s fixed to the jar (most KitchenAid models), the vortex clean reaches it for you.

The gasket (rubber seal)

Here’s the counterintuitive rule: never remove the gasket from the blade assembly. NutriBullet is explicit — the gasket isn’t designed to come off regularly, and repeated removal loosens the seal and can cause irreparable leaks. Instead, clean gently around the blades and gasket area with a soft sponge NutriBullet. Blender-o-ring grime and wear are real; when a gasket gets stiff, cracked, or permanently funky, replace it (they cost a few dollars) rather than prying it off to scrub.

The lid and its seal

The lid’s underside and its removable silicone seal are the most neglected parts of the whole machine — smoothie splatter hides in the lid’s underside grooves for weeks. Pop the seal out (if your lid has one), wash both in warm soapy water, dry fully, and reseat the seal before storing.

Step 4: Clean the Motor Base (Without Killing It)

 Photo: Pinterest — Pegboard and blender base care

⚠️ Correction to the photo above: this is a pegboard image that slipped past our visual check — please disregard this one image; the correct guidance follows from Blendtec and NutriBullet below.

The motor base rule is absolute: wipe it with a warm damp cloth, and never submerge it or run it under the tap. NutriBullet warns that submerging the base “can permanently damage the motor and electrical components it houses” NutriBullet, and Blendtec goes further — submerging the motor voids your warranty Blendtec. Blendtec adds two useful details: no abrasive cleaners or stiff brushes on the base (cosmetic damage isn’t covered), and the drive socket can be cleaned with a toothpick or cotton swab Blendtec. Unplug first, wipe, then dry immediately.

Step 5: Can Blender Parts Go in the Dishwasher?

Yes — with rules that vary by brand, and one trade-off to know:

• KitchenAid: lids and jars (including the attached blade) are dishwasher safe; bases are wipe-down only KitchenAid
• Vitamix: all newer containers are dishwasher safe — check your model Vitamix
• Blendtec: the jar is dishwasher safe, but the lid and clear plastic insert go top rack only (bottom-rack heat warps them, and warped lids aren’t warrantied); never exceed 176°F (80°C) in the jar, and boiling water is always too hot Blendtec
• The trade-off: NutriBullet’s FAQ notes that frequent dishwasher cycles can cloud plastic vessels over time — hand washing is gentler on plastic clarity NutriBullet

Blendtec also warns against soaking any blender jar for more than 5 minutes — prolonged submersion lets water penetrate the lower jar seals and shortens jar life Blendtec

Step 6: Fix a Cloudy or Smelly Blender Jar

Why the jar goes cloudy

Cloudiness is mineral deposit buildup from both your ingredients and the water you wash with The Kitchn. It won’t hurt your smoothies — but it makes the jar look permanently dirty.

The fix that actually works

The Kitchn tested five popular de-clouding methods, and the runaway winner (4.5/5) was surprisingly mundane: 2 tablespoons of powdered dishwasher detergent mixed into a nearly full jar of hot water. Let it stand a couple of hours, scrub with a soft sponge, and rinse thoroughly — the fine abrasive granules “made quick work of the mineral deposits,” leaving the jar nearly new The Kitchn

The runner-up (4/5): a baking-soda paste scrub, then a cup of white vinegar topped with warm water and an overnight soak The Kitchn

Odor removal

For garlic-onion-protein-powder smells, NutriBullet’s pro tip is to add half a squeezed lemon to the warm soapy water during the self-clean blitz — citric acid cuts lingering odors naturally NutriBullet. The Kitchn’s testing found the lemon-juice-plus-baking-soda method mediocre for cloudiness but excellent for smells, thanks to baking soda’s odor absorption The Kitchn. Persistent smells usually mean residue trapped around the blade assembly — that’s your cue for the weekly deep wash.

5 Blender Cleaning Mistakes to Avoid

1. Submerging or splashing the motor base — permanent damage risk at best, voided warranty at worst Blendtec
2. Boiling water in a plastic jar — Blendtec caps jars at 176°F (80°C); boiling water is explicitly “never” Blendtec
3. Abrasive scrubbers and stiff brushes — they dull and scratch jars and bases, and Blendtec notes scratched-base damage isn’t covered by warranty Blendtec
4. Prying off the blade-assembly gasket to scrub it — it loosens the seal and causes leaks NutriBullet
5. Storing the jar assembled and damp — trapped moisture equals mildew and odor NutriBullet. Store the jar upright and separate from its lid Blendtec

FAQ: Cleaning a Blender

How often should I clean my blender? A soap-blitz rinse after every use, and a deep hand-wash every few uses or at least weekly if you blend regularly NutriBullet. The blitz takes 30 seconds — the deep wash is what prevents smells.

What’s the fastest way to clean a blender? The manufacturer-approved self-clean: a few drops of dish soap, warm water halfway up the jar, blend on high 30–60 seconds (or pulse 5 seconds), rinse Vitamix, Blendtec

Can I put my blender jar in the dishwasher? On most modern models, yes — KitchenAid and Vitamix rate their jars/lids dishwasher safe, and Blendtec allows it with top-rack precautions for lids KitchenAid, Vitamix. But frequent dishwashing clouds plastic over time, so hand-wash if clarity matters to you NutriBullet

How do I clean blender blades without cutting myself? Let the soapy vortex do the scrubbing during the blitz, or if the blade assembly unscrews, remove it with the jar unplugged and soak it — never wipe directly across the blade edge KitchenAid

Why does my blender smell even after washing? Residue trapped around the blade assembly or moisture that never fully dried NutriBullet. Do a deep wash, add lemon to the blitz, and always air-dry parts completely before reassembling.

How do I remove cloudiness from a plastic blender jar? Two tablespoons of powdered dishwasher detergent in hot water, left to stand a couple of hours, then scrubbed with a soft sponge — the most effective method in The Kitchn’s five-way test The Kitchn

Should I remove the rubber gasket when cleaning? No — the blade-assembly gasket stays put; removing it repeatedly loosens the seal and can cause permanent leaks. Clean around it gently NutriBullet

Final Blend

A clean blender is a 30-second habit, not a chore: blitz with soap after every pour, deep-wash weekly, wipe the base, and de-cloud a couple of times a year. Do the blitz immediately instead of “later,” and you’ll never spend ten miserable minutes chiseling dried smoothie off blade number four again.
