Cleaning Instructions for Blender Bottles
We recommend washing your blender bottle after each use; that will prevent odors from developing.
Hand Washing Your Blender Bottle
The easiest way to wash your blender bottle is by hand. Depending on the design, the heat from the dishwasher can easily damage the seal, which would result in leaks.
Step 1: Disassemble the Bottle

Start by disassembling the parts; that will prevent certain areas from retaining smells or flavors.
Step 2: Soak In Soapy Water

Fill the sink with warm water and add a bit of dish soap to create a solution, then place the bottle parts in.
Step 3: Scrub and Rinse

Gently scrub the parts with a bottle cleaning brush, then rinse with water.
Supply:
- Dish soap
- Water
- Bottle cleaning brush (optional)
Avoid using abrasive cleaners as they can damage the plastic parts.
Using the Dishwasher
If your shaker bottle is dishwasher safe, you can also put it in the dishwasher.
Supplies:
- Dish soap
Step 1:
Unscrew the lid, and place the parts on the top rack.

Step 2:
Add some dish soap and run a regular cleaning cycle.

Keep in mind that this method might cause the labels to dissolve, which can make it sticky over time.
How to Remove Odors From Shaker Cups
There are a few things you can do if your protein shaker smells or is retaining odors:
Use Baking Soda
Baking soda is a great cleaning agent that most of us already have in the house.
Supplies:
- Baking soda
- Warm water

Step 1:
Add one teaspoon of baking soda into the shaker bottle, then fill it with warm water and give it a good shake.

Step 2:
Pour the water out and rinse the bottle thoroughly with clean water.
If the odor is still present, leave the baking soda/water mixture in the shaker for 15 minutes before rinsing.
Use White Vinegar
White vinegar is another excellent deodorizer that’s cheap and accessible.
Supplies:
- White vinegar
- Water
Step 1:
Fill a sink with warm water and add one cup of white vinegar and mix.
Once it’s combined, disassemble your bottle and submerge the parts in the vinegar mixture.

Step 2:
Let it soak for at least one hour before removing the protein shake bottle from the sink.

You can also use apple cider vinegar if you don’t have white vinegar.
Use Hydrogen Peroxide
Hydrogen peroxide will not only deodorize your shaker bottle but it’ll also disinfect it.
Supplies:
- Hydrogen peroxide
- Water
- Dish soap

Step 1:
Start by rinsing the bottle with water and dish soap.

Step 2:
Pour 1/4 cup of hydrogen peroxide into the vessel, close the lid tightly, and give it a good shake.

Step 3:
Pour the contents out and rinse thoroughly with water.
For the best results, use a 3% hydrogen peroxide solution.
Use Lemon Juice
Lemon juice has acidic properties, which allows it to remove odors quickly and easily.
Supplies:
- Small bowl
- Lemon
- Water
Step 1:
Squeeze the fruit for the juice over a small bowl or cup and mix it with water.

Step 2:
Pour the lemon juice solution into the bottle and swirl it around to spread the mixture.
If necessary, leave the contents in for a while before pouring it out—that will maximize the lemon juice’s deodorizing effects.

For extra cleaning power, you can add a pinch of baking soda.
Use Coffee Grounds
Don’t throw away your coffee grounds if you’re a coffee drinker, you can use them to clean your shaker bottle.
Supplies:
- Coffee grounds
- Oven

Step 1:
Dry out the coffee grounds by placing them in the oven for 15-20 minutes at 245F.

Step 2:
Once they’re dry, place them in your shaker cup and let it sit for a few hours before removing.
For extra cleaning power, you can leave the coffee grounds in overnight.
Use Vanilla Extract
Vanilla extract can be used to remove any unpleasant scents from your shaker bottle. Here’s how to use it.
Supplies:
- Paper towels
- Vanilla extract
Step 1:
Dampen a few paper towels with vanilla extract.

Step 2:
Place the paper towels inside the bottle and leave them in overnight.
Remove them in the morning.

For the best results, try not to over-saturate the paper towels with vanilla extract.
Freeze It
Did you know that you can also remove odors with the freezer? You don’t need anything special for this method either.
Supplies:
- Water

Step 1:
Pour a small amount of water into the bottle.

Step 2:
Place the shaker bottle into the freezer overnight. Remove it in the morning and let it thaw.
How to Prevent Odors From Developing in Shaker Bottles
Here are a few things to keep in mind when it comes to preventing odors:
Wash the Bottle After Each Use
Protein powder residue can clump up inside your bottle and that can cause an odor over time.

To prevent that, you want to wash your shaker cup as soon as you’re done with the beverage. At the very least, give it a good rinse once you get home.
Dry with a few paper towels afterward.
Keep It Dry
Bacteria thrive on moisture, which is why you want to keep your shaker bottle dry. Pay extra attention to the cap and whisk ball as water tends to accumulate in those areas.

Give the nooks and crannies a thorough cleaning with a bottle brush or pipe cleaner.
