Portable blenders are amazing — until you forget to clean one after a protein shake and come back to find a crusty, dried-up mess inside. Sound familiar?
The good news is cleaning a portable blender is incredibly easy if you do it right. Here are the three best methods for keeping your portable blender clean, fresh, and working like new.
Why Cleaning Your Portable Blender Matters
Before we get into the methods, here’s why you should clean your blender after every single use:
- Bacteria growth — Leftover smoothie or protein shake residue is the perfect environment for bacteria to grow, especially in warm conditions like a gym bag
- Blade damage — Dried-up food particles can dull your blades over time
- Bad smells — A blender that isn’t cleaned regularly develops a sour, unpleasant smell that transfers to your drinks
- Motor damage — Residue that gets into the motor area can cause long-term damage
The rule is simple: clean it the same day you use it. It takes less than a minute if you do it right.
Method 1: Self-Cleaning Mode (The Easiest Way)
Most modern portable blenders like the BlendJet 2 and Copkim have a self-cleaning function. This is by far the fastest and easiest cleaning method.
How to do it:
- Rinse out any leftover smoothie or shake with water
- Fill the blender about halfway with warm water
- Add one drop of dish soap
- Screw the lid on tightly
- Press the blend button and let it run for 30–60 seconds
- Pour out the soapy water
- Rinse with clean water once or twice
- Leave the lid off and let it air dry
Total time: About 1 minute
Best for: Daily cleaning after protein shakes and simple smoothies
Method 2: Hand Washing (Most Thorough)
For a deeper clean — especially after blending thick or sticky ingredients — hand washing is the way to go.
What you need:
- Dish soap
- A small bottle brush or cleaning brush (many portable blenders come with one)
- Warm water
How to do it:
- Unscrew the blade assembly from the bottom of the blender (if removable)
- Rinse the cup under warm running water to remove loose residue
- Add a small amount of dish soap to the cup and use your brush to scrub the inside walls
- Use the brush to carefully clean around and between the blades — be careful, they’re sharp
- Rinse everything thoroughly with warm water
- Leave all parts separate to air dry completely before reassembling
Total time: 3–5 minutes
Best for: Weekly deep cleaning or after thick smoothies and greasy ingredients
⚠️ Warning: Never submerge the motor base in water. Only wash the cup and blade assembly.
Method 3: Dishwasher Cleaning
Some portable blender cups and lids are dishwasher safe — but not all of them. Always check your blender’s manual before putting anything in the dishwasher.
How to check:
- Look for a “dishwasher safe” symbol on the bottom of the cup
- Check the product listing on Amazon or the manufacturer’s website
- When in doubt, hand wash — it’s safer
If your blender is dishwasher safe:
- Remove the blade assembly (never put blades in the dishwasher)
- Place the cup and lid on the top rack only
- Use a normal wash cycle
- Let everything dry completely before reassembling
Total time: Hands-off — just load and go
Best for: People who prefer low-effort cleaning and have a dishwasher-safe model
How to Remove Stubborn Stains and Smells
If your blender has developed a smell or has stained from berries or turmeric, here’s how to fix it:
For bad smells:
- Fill the blender with equal parts water and white vinegar
- Let it sit for 15–20 minutes
- Run the self-clean cycle
- Rinse thoroughly
For berry or turmeric stains:
- Make a paste of baking soda and a small amount of water
- Apply it to the stained areas and let it sit for 10 minutes
- Scrub with a soft brush and rinse
For dried protein powder:
- Soak the cup in warm soapy water for 10 minutes before cleaning
- The protein powder will loosen and come off easily
Cleaning Tips by Blender Brand
BlendJet 2:
The self-cleaning mode works extremely well. Add water and one drop of soap, blend for 30 seconds, rinse. For weekly deep cleans, the cup is hand-wash friendly. The lid and gasket should be removed and cleaned separately.
Ninja Blast:
The cup and lid are dishwasher safe (top rack only). Remove the blade assembly before dishwashing. Hand washing is also easy thanks to the wide mouth opening.
Copkim:
Has a self-cleaning function that works great for daily cleaning. The blade assembly unscrews for hand washing if needed.
Cleaning Mistakes to Avoid
- ❌ Never put the motor base in water — this will permanently damage your blender
- ❌ Never use abrasive scrubbers — they scratch the plastic and create grooves where bacteria hide
- ❌ Never put blades in the dishwasher — they can warp and become less effective
- ❌ Never store your blender with the lid on when wet — moisture trapped inside causes mold and bad smells
- ❌ Never leave it uncleaned overnight — dried smoothie is 10x harder to clean than fresh smoothie
