How to Deep Clean Your Blender Jar

facebooktwittergoogle_pluspinterest

The title of this post may sound silly since Blendtec jars nearly clean themselves. But for those who have only known old-fashioned blenders, where you have to untwist the blade to clean the blender and have the worry about protecting the rubber gasket and not poking yourself with the thin crisscross blade…let me walk you through how I clean my Blendtec blender jars.

First off, let me start by saying I use multiple jars every day: Twister, WildSide* and FourSide, depending on what I’ve decided to create. I actually use my jars like mixing bowls. If I am blending up a quick bread, I grind my wheat berries into flour in the FourSide jar, place my wet ingredients in the WildSide jar, dump a third of the flour from the FourSide into the WildSide, and ta-da! Quick bread batter in mere minutes.

To clean up, I add a little water, one drop of dish soap (note the words “one drop”) and then just put the jar back on the blender with the lid. I hit “pulse” a few times, dump the sudsy water, rinse the jar with running tap water, turn it upside down on a dish towel to air dry and I am on to the next task. Easy peasy!

Just one drop of soap in your Blendtec blender jar

Now, if I have made fresh nut butter in the Twister jar, I admit cleaning the jar is a longer process – but not that long. Here’s what I have learned.

I use the Spectacula spatula to pull out all that fresh yummy nut butter. Then I put the Twister jar back on the blender with the Twister lid on and hit “Pulse.” This throws the nut butter that was clinging under the blade to the sides of the jar. I scrape the jar clean again, then add to the jar a few tablespoons of water, plus a tiny drop of dish soap. Pulse, pulse, rinse, rinse. I tilt the jar so I can see all angles, and if it meets my approval, I am done. If not, I put the jar on the top rack of the dishwasher and that’s it!

Ok, so it’s canning season and I’ve canned several batches of salsa. Cleaning the blender jar is just as easy. But to be sure there is no leftover heat from a hot chili pepper, I just put the jar in the sink filled with suds and a little bleach. I rinse the jar, then turn it upside down to dry. All the water runs off the jar with the help of the little drain holes on the bottom of the jar. Thank you, gravity! (And thank you engineers!)

As I said, the jars nearly clean themselves. How do you clean your jar? Here’s some more tips on how to maintain your blender jars.

Here’s some more tips for removing stains from your jar:

  • Juice of 1 lemon, 2-3 tbsp of baking soda, and some water. Then, run to Speed 10 and scrub with non-scratch sponge.
  • Vinegar mixed with baking soda (and some water) will also work. Then, run to Speed 10 and scrub with non-scratch sponge.
  • 1-2 tbsp powdered dishwasher detergent dissolved in 1-2 cups hot water, left to soak for 1 hour. Then, scrub with non-scratch sponge.
  • To get ‘smells’ out, just grinding up a lemon works like it does for your garbage disposal.
  • Put in six squirts of Bleach in the jar.  Let it sit in the jar for about 5 minutes and rinse well before blending.
  • Lemi Shine® is a dishwasher detergent additive.  Combined with your auto dish detergent, Lemi Shine® Original removes tough hard water spots, stains, and film during the main wash cycle.
  • Protein powder – Lemi Shine® will also help with the protein powder.  Let soak in the jar for 20 min with some powdered dish washer detergent.

    • Hi Michelle,
      I’ve had a few suggestions come through from employees here. Most have been to use white vinegar with warm water, but I know you said that isn’t working. Another was to use a Magic Eraser, or to call our customer service if the jar is still under warranty. You’re also welcome to send us a picture so we can see what’s going on. Sometimes a jar will get crazings which are small clouded spots that can happen in the material. I hope that helps. Thanks

          Thanks for the question. This could be answered with a simple, “No, you cannot remove crazing, and yes, you can prevent crazing,” but here is the longer answer.
          Our jars are made from a copolyester material. Crazing on copolyester generally occurs from a chemical interaction with a cleaner or an oil, such as an essential oil. Crazing may appear as a cloudy fog or tiny cracks. However, these effects are purely cosmetic and do not impact the integrity of the jar. There is a great definition of crazing on Wikipedia, if you are interested. If you have further questions, our Customer Service Agents are always willing to assist. Happy Blending!

    Is there a certain amount of uses of the Wildside jar before we should replace it? It isn’t blending like it used to. I’ve owned it for almost a year and we’ve blended 380 times. It just doesn’t blend frozen berries like the first 1-280 times. Thanks!

    • Julie

      Hi Jeremie,
      Our customer service agents can help you. They can answer any concerns you have regarding your machine or jar. They are experts at listening to jars over the phone. Yes, they can tell what the jar sounds like, even long distance, to see if it is functioning properly. Give them a call at 1 800 Blendtec or 801 222 0888, they are happy to help.

    I am having trouble with the mineral buildup on my jar. Can you elaborate on the white vinegar solution? Thanks so much in advance! I love my blender!!! :)

    • Hi Katie,
      The white vinegar and warm water solution helps to remove hard water build up. However, since our jars are made from a copolyester material crazing may occur from a chemical interaction with a cleaner or an oil, such as an essential oil. Crazing may appear as a cloudy fog or tiny cracks. These effects are only cosmetic and you can still use your jar(s) without any problems, but the white vinegar solution will not remove any crazing. I hope this helps.

  • Shannon Wallace

    I use basically the same techniques EXCEPT that we never put anything from the Blendtec into the dishwasher…ever! I would personally advise everyone who owns a Blendtec to never put any of the jars into the dishwasher. It’s hard on them and will eventually wear them out sooner than if you had just hand washed them.

  • Chris

    Your post title mentions deep cleaning but then proceeds only to cover normal cleaning. To me, a deep cleaning is what I need after I get back to the house to discover dense dried-on smoothie gunk left over from having to rush out of the house with the jar half-full of smoothie sitting on the counter on a hot day.

    We generally soak it in hot soapy water for an hour or so and then scrub with a dish brush before sticking it back on the motor to pulse the soapy water. After losing several Vitamix blade assemblies to the dishwasher over the years, we’re hesitant to believe the Blendtec manual that the jar is safe for the dishwasher top rack), but I’d love to hear your take on how to do an actual deep clean, since I’m sure I’m not the only parent who is occasionally too busy to clean my blender immediately after use.

    • Hi Chris,
      While it is so easy to take just a few extra seconds to pulse, clean and rinse the jar there are life moments when schedules scream and the jar just sits.
      Cleaning off dried sticky blended food is done best, as you said, by soaking in a sink of warm water with dish soap. After soaking use a dish cloth to reach into the jar and get into the corners of the machine. The wide jar base allows your hand to reach and clean easily. Be careful when using dish brushes as some can scratch the jar. Never use a scouring pad on the jar as it will scratch the copolyester material.
      Or
      You really can wash the jar in the dishwasher on the top rack (newer dishwashers allow for this) be sure to turn off the drying cycle.

      Hope that helps

    i am having trouble making anything with more than a few cubes of ice.
    I had a recipe calling for 15 ice cubes…
    i added the almond milk, the other ingredients to taste, then the ice and hit ice/ice cream and the ice kept jamming up…
    i had to constantly stop, stir, and start again

    So the next time i tried crushing the ice before hitting start…
    worked well until a little cube lodged under the blade (i’m assuming)…then it jammed again and i had to stir it

    A $400+ machine shouldn’t jam up when using ice…what am i doing wrong?

    thanks,
    jain

    I recently noticed after years of using and having a BlendTec (e.g. over 6 years now) that the underside of the jar – the ring is getting for lack of better terms – funky. It’s almost like it is starting to etch away. Just now I made a smoothie and when I lifted the jar up from the blender itself there were little pieces of black plastic stuck to the top of the blender unit and also to the underside of the jar.

    Not sure what to do?

  • Mark

    I just bought the Designer Series and I love it. Made pretzels and tortilla soup from the recipes in the book. And it makes great smoothies using fresh rice milk, bananas, oranges, and frozen strawberries.

    And cleaning it is a breeze with putting a little bit of water and soap into the wildside jar and running it for 5-10 seconds and rinse it out. I didn’t see any mention of it in the owners manual, but is it safe/ok to use a dish towel to dry the container so dry water marks don’t show up like air drying does?

  • Dhara

    Hi,

    I purchased blendtec a few months ago, and must admit that it has been a precious addition to my kitchen. Juices and smoothies sound so easy to make that they are an everyday routine now.

    But after about 600 uses now, the wild side jar looks dirty as if it is few years old. Could you help me with some way to clean it?

    Thanks,
    Dhara

    • Hi Dhara,

  • Terez

    I don’t get this “one drop of dishwashing liquid” part. When I use just one drop, the jar doesn’t get clean. I tend to make “bulletproof coffee” and put a bit of butter with coffee in and blend them. And I make salad dressing and mayonnaise. I guess these are all greasy things but I have to give a pretty good squirt of dishwashing detergent.

  • Terri

    I was looking at this website to see if I could put my blendtec in the dishwasher. I am moving and will have one, I haven’t in the past and despite all the claims I see that just soap and water will clean the jar, that isn’t so. Maybe I started to use a wrong kind of scrubber on it in the beginning but there are scratches and I always get chia seeds that don’t come off with using just soap and water, in fact I also put in some baking soda but it still needs to be wiped down. Someday when I get a new one I’ll have to see if I can keep that unscratched.

  • Tanya Smith

    I have a relatively new Blendtec. The jar has turned green/yellow recently- likely from from my smoothies. I don’t leave them in it long but am quite surprised. I don’t want to put bleach or anything inside. Suggestions?

  • maurilio leon

    i really enjoy my blender, but the blender is cloudy and looks horrible on the blender. how do i fix the my “cloudy” blender jar? can i return it?

    • Hello,
      The cloudy look of your jar is called crazing. Our jars are made from a copolyester material. Crazing on copolyester generally occurs from a chemical interaction with a cleaner or an oil, such as an essential oil. Crazing may appear as a cloudy fog or tiny cracks. However, these effects are purely cosmetic and do not impact the integrity of the jar. Thanks for the question. Unfortunately, you cannot remove crazing, but you can prevent by following these steps: http://www.blendtec.com/blog/2013/10/04/how-to-maintain-your-blender-jar/

    Hi there, Last night I blended a mixture with curry spices in it and it stained my blendtec jar yellow! I have tried, vinegar, baking soda and olive oil. The stain remains. Is it true that denture tablets in hot water is a good way to remove stains? what does blendtec suggest for removing stains like this? thanks.

          • Hi Paul,
            Here are some more tips for cleaning your jar.

            What we recommend:
            1. Fill the jar with hot water.
            2. Add 1-2 teaspoons of liquid chlorine bleach.
            3. Stir for 10 seconds to mix water and bleach. Let mixture stand in jar for 5 minutes.
            4. Empty water/bleach mixture. Turn jar upside down on dish rack until dry.

            Others have found success with:
            – Juice of 1 lemon, 2-3 Tbsp of baking soda, and some water. Then, run on a high speed and scrub with non-scratch sponge.

            – Vinegar mixed with baking soda (and some water) will also work. Then, run on a high speed and scrub with non-scratch sponge.

            – Or, 1-2 Tbsp. powdered dishwasher detergent dissolved in 1-2 cups hot water, left to soak for 1 hour. Then, scrub with non-scratch sponge.

            – To get ‘smells’ out, just grinding up a lemon works like it does for your garbage disposal.

            Combine Lemi Shine® Original with some powdered dish washer detergent and let soak in the jar for 20 minutes.

  • Steve Means

    Thanks for the article! I’ve started making nut butters with the twister jar (which is awesome BTW) and cleanup was a pain. Using these instructions it’s simple and takes less than 5 minutes to get it spotless.

  • Mardi Sifuentes

    I made salsa in my blender jar and my friend washed it after. I don’t think she washed it very well after, because now the rubber lid smells like the salsa and no matter how many times I wash it, it still stinks. I even tried boiling the lid in hot water hoping it would “sanitize” it. I’ve heard of this happening before but have never heard of a solution. Help!

  • Paul

    Hi I was blending some fruit powder acerola berry cause it was clumpy and now it seems to have built up the powder inside the plastic under the blade like it squeezed through the ring under the blade..
    Its making the blade sluggish to turn putting strain on the motor..
    Can I remove the blade and open that area for cleaning?
    There’s no way to get in their otherwise..
    Thanks

    • Hi Paul,
      There is no way to remove the blade for cleaning.
      If your jar is not working properly, we may be able to replace, if it’s still under warranty. Please call 800.748.5400 for assistance. You will need to be near your blender when you call.

  • annie

    We make green smoothies everyday…our jar gets a brownish minerally build up. I put in extra soap and rise super well, but it still builds up and looks terrible. We are move a lot so at the mercy of what ever water (and minerals) are in each location, buti even in a really soft water place we still get build-up. Is there something that will clean it better, like a once-a-month cleaner? (I hate the looks, but hate to have you replace it just because of the looks.)

    • Plastic discoloration is a possibility when blending certain items such as certain protein powders, certain spices, dry goods, etc. When regular cleaning does not remove these stains, there are a few other things that can help diminish the appearance which are listed below. Some of these tips will work better for certain types of stains, while other tips might work better for another type of stain, so if one doesn’t seem to do the trick, try out another.

      Tips for removing stains from your jar:

      Juice of 1 lemon, 2-3 tbsp of baking soda, and some water. Then, run to Speed 10 and scrub with non-scratch sponge.
      Vinegar mixed with baking soda (and some water) will also work. Then, run to Speed 10 and scrub with non-scratch sponge.

  • Gregory Santollo

    Yeah I have had my current jar for 2000 blends. I think it is just time to order a new jar, as I have tried everything to clean it in recent months, with very little success at getting the brown mineral stains out. (which prevents me from instargraming my 3x daily smoothies.) I just wanted to know if anyone else noticed a fermentation type after taste in there blender… I have eaten all my ingredients separately as well as mixed in another blender and I don’t taste it but when blended in my blendtec with current jar I have a weird after taste. Any thoughts?

    thanks GREG.

    I have one of these old fashioned blenders and I love it. I admit that I am not exactly sure how should I clean it. Thank you for the interesting cleaning solutions here! I will try them!

    I have a sour milk smell in the opening to the base of the blender. It also gets on the bottom insert of the blender jar. How can I get rid of that horrible smell?
