Protein shakes are delicious. They are a great way to get in some lean protein, and can be eaten on the go if needed. Blenders can be a pain though. Here is a quick cleaning tip for you. Once you make your shake rinse out your blender with water. Fill it up about 1/3 full with hot water and some dish soap, and then put the lid back on and blend up the water/soap solution. It is a great FAST way to clean your blender, and get all the way down to the blades. Rinse out the soap and set it on a towel to air dry. Easy as that!
