"After you’ve made your smoothie you have to wash that blender. It can be difficult and, no matter how hard you try, the smell of the ingredients can stay for a long time. But there is a very simple way to get your blender perfectly clean. After making your smoothie, just pour some water in it, add a splash of dishwashing liquid, blend it, and it will wash itself. All you need to do now is just rinse it off."
