After blending up something sticky, gooey or smelly, just place a few drops of soap in the carriage with some warm water and blend on high until all of the congealed food slips away from the blades and sides. Then repeat this process. Then rinse with water and presto! Clean carriage.
If you have smells or stains repeat this process with some bicarbonate of soda or lemon juice and water.
Check out the video on A No Hassle Way To Clean Your Blender that I did as part of the Chow Tips Series.
