The best thing about making smoothies as that there really is no wrong way. It all depends on your personal tastes and desires. You can spend time experimenting if you want to, adding a little of this and a little of that and seeing how it tastes. Take a standing recipe and tweaking a little, adding or substituting. Some dont want to take the time to experiment and want a recipe that is know to work. This site will have many recipes to try and there are many out there on the web with countless sites.
Its best with all blenders to start out adding your liquids, then your softer items and last put in your harder ingredients (like ice and frozen fruits). This especially true for your lower end blenders that are not that powerful. This will make it easier for your blender to get going and be less of a strain. Also start off at a lower speed and quickly work up to the highest.
When you are done rinse out the container. Then fill it up about 1/2 to 3/4 full of hot soapy water. Next just run the blender then rinse again! its that easy and ready again for your lunch time smoothy!
