How to clean protein shakes from a blender/shaker bottle.
Have you ever forgotten a protein shake (or a batter mix, like for protein pancakes) in your shaker bottle? The smell is ungodly, and can permeate your bottle even after soaking and washing. But I’ve found a great way to clean them.
Cleaning Blender Bottles
I use Blender Bottles to make my protein shakes (no more clumps stuck to a spoon or extra dirty dishes!) but if I don’t wash them the same day, they’ll start to reek once I crack them back open. Remove the metal shaker ball, since that won’t smell after you soak it, add a tablespoon (or about 1/3 of an ounce) of white vinegar to the bottle, fill the rest of the way with water, and let it soak in the vinegar overnight. The smell will be gone and you can wash it by hand or plunk it in the dishwasher the next time you run a load.
