• If your blender has a Clean cycle, just add a cup of water and a drop or two of dish soap to your jar, replace the lid, run the cycle, and rinse. If your blender does not have a Clean cycle, add the same amount of water and soap, replace the lid, Pulse a few times, and rinse.

  • You can keep your jar running smoothly with these tips and tricks:

    • Spin the blade manually by the shaft on the bottom of the jar before each use to lubricate the blade shaft.
    • Don't use your jar as a storage container or let liquids sit in the jar overnight.
    • Wash your jar or use the Clean cycle immediately after use.


  • The maximum temperature we recommend exposing the jar to is 176°F (80°C). Things get hotter as they blend, so avoid adding ingredients over 115°F (46°C). Please keep in mind that boiling water is too hot for the jar and should never be poured into the jar.

  • WildSide+ jar: 90 oz capacity jar with measurements up to 36 oz*

    FourSide jar: 75 oz capacity jar with measurements up to 32 oz*

    Mini WildSide jar: 46 oz capacity jar with measurements up to 24 oz*

    Twister jar: 37 oz capacity jar with measurements up to 16 oz*

    Mini Twister jar: 28 oz capacity jar with measurements up to 12 oz*

    *We recommend that the finished blended product stays at or below this line.

  • Our jars are made of Eastman Tritan™ copolyester. You can learn more about it here: http://www.eastman.com/Brands/Eastman_Tritan/Pages/Overview.aspx 

  • The blade spins over 300 miles per hour, so it doesn't need to be sharp to get the job done. Instead of chipping away at ice and frozen fruit with sharp edges, the large, blunt design pulverizes virtually anything.

  • Most blending problems can be avoided by loading your jar properly. Always load your blender with liquids first, followed by soft solids like bananas or spinach, and then hard dense items like ice and frozen ingredients. Always secure lid before blending.

  • The main difference between the FourSide and WildSide+ jars is size. The FourSide jar is slightly smaller, and the WildSide+ jar has a wider base and larger blade.

    The FourSide jar has a 3" blade and a capacity of 75 oz (9.375 cups) with markings up to 32 oz (4 cups). We recommend that the finished blended product stays at or below this line. 

    The WildSide+ jar has a fifth side and is designed for larger, faster blends. It has a 4" blade and a capacity of 90 oz (11.25 cups), however, the markings are up to 36 oz (4.5 cups). We recommend that the finished blended product stays at or below this line. There are also two vertical ridges in the jar's interior that allow ingredients to hit two additional surfaces. This accelerates the blending process and makes a smoother blend.

  • Grinding grains, legumes, beans, rice, or nuts may result in a fogged appearance. Using some greens, spices, and protein powders will also cause it to have a cloudy appearance. Please note that this is a cosmetic alteration and is not covered under your jar warranty. It does not affect the performance of the jar.

    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:

    • Add the juice of 1 lemon, 2-3 tbsp of baking soda, and some water to jar. Run on a high speed for about 10 seconds, pour the water out and scrub with a non-scratch sponge. 
    • Vinegar mixed with baking soda and some water will also work. Run on a high speed for about 10 seconds, pour the water out and scrub with a non-scratch sponge.
    • Add 1-2 tbsp powdered dishwasher detergent dissolved in 1-2 cups hot water, let soak for 1 hour. Then, scrub with a non-scratch sponge. 
    • Combine Lemi Shine® Original with some powdered dishwasher detergent and let soak in the jar for 20 minutes. 
  • Two reasons: 

    1. Safety is our top priority. Blendtec blenders are among the most powerful on the planet, and their jars have to handle high-speed impacts from very hard ingredients like frozen fruit. Glass jars have the potential to shatter not only when dropped, but also during high-speed blending. Blendtec's Tritan copolyester jars are engineered to withstand that kind of stress. 
    2. Lighter is better. Blendtec jars are very light and are molded for easy gripping and storage. Glass jars, on the other hand, are heavier and more difficult to grip, pour, and store.
