Are Blenders Dishwasher Safe? What You Can (and Can’t) Wash

Ever had a moment after blending a protein shake or purée where you’re staring at your messy blender and asking yourself, “Can I just throw all of this into the dishwasher?” It feels like the easy way out, especially when food splatters are drying up fast and you’re in no mood to scrub.

But here’s the truth—you can’t just toss the whole blender into the dishwasher without thinking. Some parts are dishwasher safe, others aren’t, and certain brands play by their own rules. Washing the wrong part the wrong way could ruin it, dull the blades, warp the seal, or even shorten your blender’s lifespan. And no one wants that—especially if you’ve invested in something like a Vitamix or Ninja.

Let’s break this down step by step, covering all the parts, brands, and practical cleaning methods to help you know exactly what to do next time that smoothie splatters all over the lid.

So, Can You Put a Blender in the Dishwasher?

Here’s the most straightforward answer: Yes, but only certain parts—and only if your specific model allows it.

Most countertop blenders come with a few removable components: the pitcher (or jar), the lid, the blade base, and a gasket (rubber seal). These parts are often made of plastic, glass, rubber, or stainless steel—all materials that can usually survive the dishwasher.

But the motor base—the part that plugs into the wall and powers the blender—should never go in. That part contains electrical circuits that will be damaged immediately by moisture, heat, or steam. If you toss that in the dishwasher, it’s game over.

Also, not every manufacturer recommends dishwasher cleaning for all parts, even if technically they can survive a wash cycle. Some brands suggest hand washing to extend the life of key components like the blades and gaskets. It’s not always about what’s possible—it’s about what’s smart for long-term performance.

Dishwasher-safe Blender Parts

To make this easier to remember, here’s how most blender parts behave with dishwashers:

1. Blender Jar (aka Pitcher or Container)

Plastic and glass jars are usually dishwasher-safe. Most brands allow them on the top rack. This keeps them away from the intense heat that rises from the bottom.
That said, plastic jars can become cloudy or scratched over time, especially if your dishwasher uses aggressive detergent. You might notice this especially if you’re washing daily.

2. Lid and Cap

These are generally safe for dishwasher cleaning—again, ideally on the top rack. They’re small, easy to rinse, and made to withstand dishwasher heat.

But if your blender lid has a silicone seal or flip cap, check if those parts detach. They can trap food particles and mold if not cleaned regularly.

3. Blade Assembly

This one’s tricky. If your blender has a removable blade base (like many Ninja and Oster models), the metal part can technically go into the dishwasher. But here’s the catch:
Dishwasher heat can dull sharp edges over time.
Plus, trapped moisture between metal and plastic may cause rust or loosen glued components. That’s why many manufacturers recommend hand washing blades, even when dishwasher use is allowed.

Pro tip: If you must put blades in the dishwasher, use the top rack, and avoid high-heat settings like “sanitize.”

4. Rubber Gasket or Seal

This flexible ring creates an airtight seal between the pitcher and the blade base. It’s usually dishwasher safe—but often ignored. When left unwashed, gaskets can develop mildew or foul smells from trapped moisture and food bits.

Always remove it from the blade base and wash it separately, especially if you’re blending thick foods like peanut butter or hummus.

5. Motor Base (Never Dishwasher Safe)

This is the powerhouse of your blender, and it should never get wet. Only wipe it down with a slightly damp cloth. Keep moisture away from buttons, displays, and the bottom vents.

Mistake to avoid: Some people try to “deep clean” by spraying it with kitchen cleaner. Don’t. Just use a damp microfiber cloth and dry it immediately.

Hand Wash vs Dishwasher Cleaning

If convenience is your main priority, then the dishwasher wins—no question. Just drop in your blender parts, press a button, and walk away.

But if you’re more concerned about keeping your blender working like new, hand washing may be better in the long run.

Here’s why:

• Dishwasher cycles are rougher than we think—lots of heat, pressure, and detergent.

• Blades can dull faster.

• Plastic jars can warp or get that foggy look after many washes.

• Gaskets may loosen or crack.

So, what’s the sweet spot? A hybrid approach.

• Blend soapy water in your pitcher for 30 seconds, rinse, and wipe down—this works for everyday cleaning.

• Then, once or twice a week, disassemble and wash parts by hand using warm water and gentle dish soap.

• Or, if you’re using the dishwasher, only put the lid, jar, and cap on the top rack, and hand wash blades and gaskets.

This approach keeps your blender performing well without sacrificing your time.

Are Hand Blenders Dishwasher Safe Too?

Hand blenders (also called immersion blenders) are a different beast altogether. They’re the handheld tools you stick directly into pots or bowls for quick blending—great for soups, sauces, or baby food.

But can you toss them in the dishwasher? Here’s the breakdown:

What You Can Wash

• The detachable blending arm or wand (the metal or plastic stick with blades at the end) is usually dishwasher safe, especially if it clicks off from the motor.

• The whisk and chopping attachments that come with some hand blenders can also go in—just make sure they’re rated for it.

• Are cups and jars included in the package? Also safe, usually top rack.

What You Should Never Wash

• The motor handle (where the power button is) should never get soaked. This part contains the actual motor and is usually NOT waterproof.

• Avoid submerging or putting the motor section near steam from the dishwasher—it can cause internal condensation and damage over time.

Quick tip: If your hand blender comes with a food processor bowl or lid, check for gaskets or locking pieces. Those often need a rinse under warm water to prevent mold buildup.

Brand-Specific Guidelines & Recommendations

Every brand has its quirks. Some make cleaning super easy, others expect you to do a bit more maintenance. Let’s look at the popular ones:

Nutribullet

• Dishwasher-safe parts: Cup, lid, and extractor blade (top rack only).

• What to avoid: High-heat cycles can warp lids or dull the blade sooner than expected.

• Extra advice: Nutribullet blades have rubber seals—make sure those get cleaned every single time to prevent leaks or mold.

Vitamix

• Mostly hand-wash only.

• Containers are self-cleaning—just blend warm water with dish soap and rinse.

• Some newer models have dishwasher-safe containers (check your model number).

• Why the caution? Vitamix containers are high-performance and expensive—best to hand wash if you want them to last years.

Ninja

• Dishwasher-safe parts: Jar, lid, blades, and accessories (top rack).

• However, blade bases are very sharp and can get damaged with frequent dishwashing.

• What to avoid: Gaskets on some Ninja models aren’t removable—so clean them thoroughly after blending sticky or oily ingredients.

Hamilton Beach

• Budget-friendly and mostly dishwasher safe.

• Pitchers, lids, and blades can go in the dishwasher—but again, always use the top rack.

• The motor base must be wiped clean only.

Oster

• Known for durable glass jars, which are top-rack dishwasher safe.

• Blades are removable and often go in, but to avoid wear, it’s smarter to hand wash.

• Older models may not separate—if yours doesn’t, blend warm soapy water to clean internally.

Common Mistakes to Avoid When Washing Your Blender

Here’s where people go wrong—and end up with broken, smelly, or leaking blenders.

• Washing blades in the bottom rack: That’s dishwasher death for sharp edges.

• Forgetting to detach the gasket: This leads to mold and unpleasant smells.

• Not drying parts completely after washing: Blades rust. Seals loosen. Always dry thoroughly.

• Soaking the base in water to clean it: Don’t do this—ever. Just wipe it down.

• Using abrasive pads or harsh cleaners: These can scratch plastic jars and make them cloudy or dull.

Best Practices for Long-Term Blender Care

If you want your blender to last for years without weird smells, leaks, or weakened blades, here’s your go-to routine:

1. Rinse right after blending—even if you plan to wash later.

2. Blend warm water and dish soap for quick cleaning when in a hurry.

3. Disassemble and clean deeply once a week—focus on the gasket and under the blade base.

4. Use the top rack only if dishwashing.

5. Dry each part completely before reassembly to prevent rust or mold.

6. Store your blender with the lid off to avoid trapped moisture and odors.

So, Is It Okay to Wash a Blender in the Dishwasher? Final Thoughts

Yes—as long as you know which parts can go in, and how to do it smartly. The pitcher, lid, and sometimes blades can survive your dishwasher, especially on the top rack. But the motor base? Never.

Whether you’re working with a Nutribullet, Ninja, Vitamix, Oster, or Hamilton Beach, always check the manual, follow brand-specific tips, and clean immediately after use when possible.
