How (and Why) to Clean Your Shaker Bottle the Right Way

We’ve all been there. You finish your shake, toss your bottle in the gym bag or leave it on the counter, and forget about it. Hours later (or the next day - hey, no judgment), you open it up and that funky smell hits you.

If you’re using a PROMIXX shaker, you’re guaranteed that smell won’t stick around. Why? Because we use high-quality ECOZEN plastic that doesn’t retain smells. That said, every unwashed shaker bottle is the perfect hangout spot for bacteria if it’s not cleaned properly. Protein residue, warm temperatures, and a sealed lid create the ideal environment for unpleasant odors and unwanted germs.

But don’t worry, keeping your shaker clean is simple. Whether you use the PROMiXX Pro with its powerful electronic mixer, or the Pursuit and Form classic bottles, cleaning is quick and easy when you know how.

It’s more than just avoiding the “forgotten milkshake” smell. Although, that’s reason enough. Regular cleaning matters because:

• Bacteria love protein residue. Leftover shake clings to the inside of your bottle and breaks down into bacteria and mold.
• Odor builds fast. That sour smell is the result of fermentation. Once it sets in, it’s hard to get rid of.
• Your health counts. Dirty bottles can harbor harmful microbes that can cause stomach issues or skin breakouts.

PROMIXX Pro is a powerful bottle with an electric motor built right in. Meaning the good news is that cleaning it is just as simple as making your shake.

Here’s the quick method:

After finishing your shake, give it a quick rinse with warm water to prevent protein from drying on.

Fill the bottle halfway.

Switch on the motor and let the Pro essentially clean itself! The spinning vortex takes care of the inside walls and corners.

Empty and rinse with clean water.

That’s it. No scrubbing. No hassle. And because there’s no wire ball or complicated parts, nothing traps leftover protein or odor.

If you’re using the Pursuit or Form classic PROMIXX bottles, you’ll love how easy they are to clean. Unlike other shakers with wire balls, our bottles use a smooth, streamlined agitator design.

Why does that matter? Because those old-school wire balls are notorious for trapping thick protein and creating hard-to-reach spots where bacteria thrive. With PROMIXX, there’s nowhere for gunk to hide.

Here’s the easy clean routine:

Warm water works best.

Use a soft bottle brush or sponge if needed. Though most of the time, a swirl of soapy water will do the job.

Leave the lid off so everything dries completely.

• Don’t delay. The sooner you rinse after drinking, the easier the clean.
• Air it out. Store with the lid open to prevent trapped moisture (and smell).
• Deep clean weekly. Add a teaspoon of baking soda or white vinegar to warm water, let sit for 30 minutes, then rinse.
• Check the lid seal. Make sure the silicone seals are clean and dry, they can hold onto residue if neglected.

A fresh, clean shaker isn’t just about hygiene. It also makes your shake taste exactly as it should - smooth, pure, and delicious.

With any PROMIXX shaker, that’s easy. The Pro’s vortex-cleaning power, and the Pursuit and Form’s wire-ball-free design, mean no stubborn protein build-up, no lingering odors, and no excuses.
