Are Shaker Bottles Dishwasher Safe?

It’s okay to put plastic, metal, and glass shaker cups on the top rack of a dishwasher, but not all the time. Eventually, the heat will destroy the rubber seal or measuring lines on the side. Try to wash your shaker cups by hand instead whenever possible.

If you’re cleaning your protein shakers in the dishwasher, stack the lid and bottle separately. The whisk ball (agitator) at the bottom should be removed and washed by hand.

How to Clean a Protein Shaker Bottle

Even if your shaker bottle is dishwasher-safe, you should still regularly clean it by hand. Follow the steps below!

  1. Step 1: Remove the lid from the protein shaker so it can be cleaned separately from the bottle.
  2. Step 2: Soak the bottle in warm, soapy water for at least 30 minutes.
  3. Step 3: Clean the lid using a soft bristle brush and a pipe cleaner for the straw.
  4. Step 4: Take the bottle out of the water. If it’s still caked in protein powder, refill the sink with warm water and let the bottle soak for another 30 minutes.
  5. Step 5: Scrub the inside and outside of the bottle using a scrub brush. Be extra thorough around the mixing ball.
  6. Step 6: Rinse any remaining suds from the lid and bottle.
  7. Step 7: Dry thoroughly with a clean towel. Leave the bottle and lid upside down on a dish rack to make sure there’s no more moisture.

Do Not Microwave

Store Bottle & Lid Separately

Take the lid off before storage. You’ll cut down on any odors that may get trapped inside, increasing the shelf life of your protein shaker.

Fill With Safe Ingredients

Fill With Safe Ingredients

Don’t fill your shaker bottle with random foods like mustard, pickle juice, shrimp, or noodles. You should use it only to make healthy protein shakes that contain ingredients like milk, oatmeal, nuts, bananas, etc.

A protein shaker isn’t meant to last forever. It gets worn down over time, especially if you’re using it 5 to 7 days a week. If you drink a lot of protein shakes, it may not be a bad idea to buy more than one shaker bottle.

The Bottom Line

You wouldn’t wear your sweaty gym clothes without washing them first. Why should your protein shaker cup be any different? Give it a good cleaning before your next workout!
