Just like soap and shower gel, most mouthwashes contain triclosan. This chemical destroys the good bacteria together with the bad which can cause an allergic reaction, a hormone imbalance, and even heart problems.
Solution: Remember that mouthwash is really only necessary for people who have a tooth infection or a gum problem. Using it every day if you have no dental problems is a bad idea.
It’s not the blender itself that is dangerous but its rubber parts. They are rarely washed and disinfected and as a result, your blender turns into a perfect place for bacteria and mold.
Solution: Just don’t forget to wash the entire blender every time you use it.
