Glass blenders are particularly easy to clean. They do not easily get scratches, and there are usually very few leftovers stuck to the jar. If your best glass blender is not dishwasher safe, here is how to manually clean it up: 01. Fill the pitcher with water halfway through. 02. Pour a dash of liquid dish soap in it. 03.Put the lid on and hold it down. 04. Turn on the blender to a medium or high setting. 05. Empty the hot water and thoroughly rinse it to get a squeaky clean jar! In case there are stuck food bits on the blade or the corners of the container, use a brush to loosen those up before starting this cycle.
