Frequently Asked Questions

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:

• 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.

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.

Our jars are made of Eastman Tritan™ copolyester. 

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. 

There are lots of things that set Blendtec blenders apart. Please visit this page to learn more.

All of our blender models will work for making nut butters. We recommend using the Twister Jar as it is the best jar option when making thicker blends like nut butters.

All blender models are designed to make ice cream.

All blender models can do this. We recommend getting a separate jar for grinding since it can make your jar look foggy.

All blender models are designed to knead dough. The best jar to use when doing this is the WildSide+ jar because it is larger and can make more dough. However, the FourSide jar will work as well.

All blender models are designed to juice whole foods.

Yes! All Blendtec blender models can to this. You can add 1-2 cups of wheat berries or other grains into your FourSide jar (or 2-3 cups in your WildSide+ jar). By grinding, your jar will permanently become cloudy. This is just cosmetic and will not harm or hamper your food; however, please note cosmetic alternations are not covered under your jar warranty. We suggest buying a separate jar for grains. 

Yes, you can! Several of our blenders have a preprogrammed "Soup" or "Hot" cycle. Even if your model doesn't have this feature, you can blend on a high speed for 90-180 seconds. The blender itself does not have a heating element; however, the length of time, combined with the friction from the speed of the blender, heats the ingredients. If your soup isn't warm enough, blend until desired temperature is reached. 

*PLEASE NOTE: 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.

Those numbers are a cycle count and show how many times you have used your blender.

Many of our recipes were developed for the Total Blender Classic Series that has six preprogrammed blend cycles. However, we have created many blender models since then that don't have those same blend cycles. To learn how to do these cycles on your blender, please visit this page to see the blend cycles conversions.

We engineer, design, and assemble our blenders in Orem, Utah, with components either manufactured in-house or sourced primarily from the USA. There are some components of the blenders that are made outside the USA, or made with foreign components or materials. Due to some fairly strict requirements, those foreign components prohibit us from saying "made" or "manufactured" in the USA without providing a lot of very specific detail. You can learn more here.

Clean your blender base with mild soap and warm water. Do not use chemicals such as Lysol Kitchen or Clorox wipes.

The mixture is probably cavitating during the cycle. Cavitation occurs when an air pocket forms within the mix because the mix is too cold or too solid. The blender blade then spins freely in this cavity. You can fix this by increasing the mix temperature. Reducing ice, increasing liquid and/or ensuring that the frozen ingredients used in the recipe are never colder than 10°F (-12°C) will help.
