These are some pretty common scenarios below:

  • You’ve forgotten to wash your protein shaker for a week
  • You left your protein shaker at your friends house after the gym

Whatever reason why you haven’t been using your protein shaker, if you haven’t washed it in a week, then it’ll smell like sh*t. Real diarrhea type sh*t (or cheesy feet).

But don’t worry, here at SpotMeBro, we’re giving you some quick fixes – to make your protein shaker smell normal and help make America great again.

Check it out:

Quick Fixes for Smelly Protein Shakes

This is the easiest fix of them all. It means you won’t have to smell the disgusting smell radiating out of the protein shaker for too long.

Just stuff it into the dishwasher and hope for the best.

In fact, we’ve seen great results with this method ourselves. But it did take 2-3 spins for the smell to completely leave the protein shaker.

What to do: 

  • Pinch nose, open & rinse protein shaker
  • Add dishwashing soap inside protein shaker
  • Stuff into dishwasher and pray to the god of gainz
  • Wash 2-3 times

2. Baking Soda

Baking soda seems to be a fix for many things recently – from helping to clean burned pans to your fridge. But you might not have known that it’s also great for getting rid of that funky-ass smell out of your protein shaker.

This fix isn’t really ‘quick’, but the title brought you here, didn’t it? So stop complaining and see what’s going on below…

What to do: 

  • Pinch nose, open & rinse protein shaker
  • Add 2 spoons of baking soda & fill with water
  • Mix, then leave for 1 hour

The final quick fix on this list. If you’ve tried all of the others and still have a protein shaker smelling like sh*t, then good luck.

Anyway, we’ve read that denture tablets (which you buy at any drugstore) will help take away the smell of your smelly protein shaker.

What to do: 

  • Pray to the god of gainz
  • Fill protein shaker with boiling water
  • Add denture tablet
  • Dance around a fire while praying to the god of gainz
  • Wash protein shaker out with soapy water


Honestly, if you’ve actually tried all 5 of those fixes and your protein shaker still smells bad…then just throw that sh*t out. Please.

Unless you have a dishwasher and you can just leave it in there for 2-3 spins, it can take a lot of time to stop your protein shaker from smelling horrible. You’ll save a lot of time by driving to a supermarket and buying a new protein shaker (or ordering one online).
