People often put protein products in blender bottles to make protein shakes or smoothies. If you clean the bottle well after each use, protein powder dust can build up and make the bottle smell good. The smelly smell comes from the germs that grow on the leftovers.

Mildew and germs

Leftover smoothie

Leftover Food

Sometimes, blender bottles are used to save extra food or snacks. If the bottle isn’t cleaned right away after holding food, food bits can stay in the bottle and break down. It can make the bottle smell bad. After using the bottle to store food, it’s important to clean it well.
