Blender Bottles are fantastic tools for creating delicious and nutritious shakes on the go. They offer convenience, portability, and a quick cleanup. But it’s important to know what you should not put in a Blender Bottle to avoid any mishaps or damage. Certain ingredients or substances may be too thick or corrosive for the bottle, potentially causing leaks or even health risks. So, before you go blending away, let’s explore some items that are better left out of your Blender Bottle.

Foods and Ingredients

Carbonated drinks

While a Blender Bottle might seem like the perfect vessel to mix your favorite carbonated beverage, it is highly advised against doing so. The pressure generated from the carbonation can cause the bottle to burst open, resulting in a big mess and potentially injuring you or those around you. It’s best to save your carbonated drinks for a regular glass or can.

Hot liquids

Blender Bottles are not designed to handle hot liquids. Pouring boiling water or any other hot liquid into the bottle can cause it to warp or even melt, compromising its structural integrity. Not only could this damage the bottle, but it could also lead to burns or spills, posing a safety risk. It’s recommended to let your hot liquids cool down before transferring them to a Blender Bottle, or opt for a different container entirely.

Dry ingredients

It may be tempting to use your Blender Bottle to mix dry ingredients, such as flour, protein powders, or powdered sugar, but this can lead to clumpy messes and uneven mixing. The narrow opening of the Blender Bottle makes it difficult for powdered ingredients to disperse evenly, resulting in lumpy mixtures. It’s better to stick to a traditional mixing bowl or a dedicated food processor for dry ingredients.

Thick sauces and dips

While Blender Bottles do an excellent job of mixing protein shakes and smoothies, they are not ideal for thick sauces or dips. The small wire BlenderBall inside the bottle is not designed to handle the viscosity of thicker mixtures. Instead, opt for a blender or food processor specifically designed to handle thicker consistencies to achieve a smooth and well-mixed sauce or dip.

Uncooked grains and seeds

Uncooked grains and seeds, such as rice, quinoa, or chia seeds, should not be added directly to a Blender Bottle. These small and hard ingredients can easily get stuck in the blending mechanism or cause damage to the bottle’s blades. It’s best to cook or soak these ingredients before including them in your blender bottle recipes, or use a dedicated food processor or grinder for more efficient blending.

Whole fruits and vegetables

While the idea of blending whole fruits and vegetables directly in your Blender Bottle might seem convenient, it’s not the best approach. The narrow opening of the bottle makes it difficult for larger chunks of fruits or vegetables to blend properly, resulting in uneven textures and potential clogging of the bottle’s blending mechanism. It’s recommended to cut your fruits and vegetables into smaller pieces or opt for a larger blender that can accommodate whole ingredients.

Ice cubes

While some Blender Bottles come with specialized ice cube trays, not all bottles are equipped to handle the pressure and impact of blending ice cubes directly. The force generated by the blades can cause the bottle to crack or even break, resulting in a mess and potential injuries. To enjoy a frosty smoothie, it’s best to crush the ice cubes separately or use a blender specifically designed for ice crushing.

Nut butters

Blender Bottles are not designed to handle the thick and sticky consistency of nut butters. Attempting to blend nuts or nut butter in a Blender Bottle can cause the bottle’s blades to get stuck or even break, leading to frustration and potential damage to the bottle. For homemade nut butters, it’s recommended to use a high-powered blender or a dedicated food processor to achieve smooth and creamy results.

Powdered spices

While it may be tempting to use your Blender Bottle to mix powdered spices, it’s not the most efficient method. The narrow opening and small blending mechanism of the bottle make it challenging to evenly distribute and mix powdered spices. It’s better to use a dedicated spice grinder or mortar and pestle for better control and consistency when working with powdered spices.


Blender Bottles are not suitable for blending raw eggs. The inconsistent and unpredictable nature of blending raw eggs can result in a mix that is nowhere near as smooth and well-incorporated as you might expect. It’s best to use a traditional whisk or electric mixer when working with eggs, ensuring proper emulsification and aeration for your recipes.

Cleaning Agents


Using bleach in a Blender Bottle is not recommended. While bleach is a powerful cleaning agent, it can react with the plastic material of the bottle and cause discoloration, deterioration, or even a strong chemical odor. It’s best to avoid using bleach altogether when cleaning your Blender Bottle and opt for safer alternatives.


Similar to bleach, ammonia is another cleaning agent that should not be used with Blender Bottles. The harsh chemical nature of ammonia can cause damage to the plastic material and potentially compromise the integrity of the bottle. It’s advisable to steer clear of using ammonia-based cleaners when it comes to your Blender Bottle.

Dish soap with bleach

While dish soap is commonly used for cleaning many kitchen items, using a dish soap that contains bleach is not recommended for your Blender Bottle. The combination of bleach and the plastic material can lead to discoloration, unpleasant odor, or even structural damage. Stick to regular dish soap or specialized bottle cleaning solutions when washing your Blender Bottle.

Baking soda and vinegar

Baking soda and vinegar are commonly used as natural cleaning agents, but they should not be used together in a Blender Bottle. The combination of baking soda and vinegar leads to a rapid fizzing reaction, which can cause the bottle to overflow or even burst open due to the pressure build-up. It’s best to avoid this combination when cleaning your Blender Bottle and choose one cleaning agent at a time.

Abrasive scrub brushes

While it’s essential to keep your Blender Bottle clean, using abrasive scrub brushes can scratch or damage the surface of the bottle. This can lead to the growth of bacteria and make it more challenging to clean in the future. Instead, opt for soft-bristle brushes or bottle cleaning tools specifically designed for your Blender Bottle to ensure thorough yet gentle cleaning.

Non-Food Items

Metal utensils

Using metal utensils inside your Blender Bottle is not recommended. The harsh contact between metal and the plastic bottle can cause scratching or damage to the surface, making it more prone to bacterial growth and contamination. It’s best to stick to non-metal utensils when using your Blender Bottle to maintain its longevity and hygiene.

Sharp objects

Avoid using sharp objects, such as knives or scissors, in or around your Blender Bottle. Accidental punctures or cuts can compromise the bottle’s structural integrity and potentially render it useless. Practice caution and keep sharp objects away from your Blender Bottle to prevent accidental damage.


It’s crucial to keep electronic devices far away from your Blender Bottle. Moisture from liquids or cleaning agents can damage electronic components and lead to malfunctions or permanent damage. Never submerge your Blender Bottle with any electronic devices attached or stored nearby to ensure their safety and optimal performance.

Plastic bags

While plastic bags may seem convenient to store or transport your Blender Bottle, it’s best to avoid using them for this purpose. The plastic material of the bag can stick to the bottle, leaving behind residue or potentially melting onto the bottle’s surface. Opt for dedicated bottle storage solutions or cloth bags that are safe for use with your Blender Bottle.

Cotton balls

Using cotton balls to clean the inside or outside of your Blender Bottle is not recommended. The fibers from cotton balls can easily become trapped in the bottle’s crevices, leading to potential bacterial growth and contamination. Instead, use soft cloths or bottle cleaning brushes specifically designed for your Blender Bottle to ensure thorough yet gentle cleaning.

In conclusion, while Blender Bottles are fantastic tools for mixing and blending various ingredients, it’s essential to be mindful of what not to put in them. Avoiding carbonated drinks, hot liquids, dry ingredients, thick sauces and dips, uncooked grains and seeds, whole fruits and vegetables, ice cubes, nut butters, powdered spices, and raw eggs ensures the longevity of your Blender Bottle and maintains safety. Additionally, using appropriate cleaning agents like dish soap without bleach, avoiding harsh substances like bleach and ammonia, and being cautious with using sharp objects or abrasive scrub brushes contribute to the proper maintenance and cleanliness of your Blender Bottle. By following these guidelines, you can make the most out of your Blender Bottle and enjoy safe and hassle-free blending experiences.
