Go Easy on Your Blender

When making frozen beverages in a blender, substitute ice with one or more of the ingredients that's been frozen such as frozen bananas or blueberries. If ice is non-negotiable in your recipe, blend with liquid. The liquid will serve as a buffer. Using the blender as essentially an ice crusher will bend and dull the blades over time.

Blend Your Blender Clean

Many modern blenders have a clean feature. But if you don't, add some warm water and dish detergent to your blender. Then blend it until the detergent suds. It makes cleaning much easier. Continue to do this until stuck on food and residue dissolves. Then wash the outside of the blender as you usually do and rinse the inside thoroughly.
