If your blender has a lingering smell, there's an easy hack to freshen it up. Simply slice some limes, add water, and blend for a minute or two. This trick works because limes have antimicrobial properties due to their high acidity and citric acid content. You can also create a cleaning spray with lime juice and vinegar to wipe down the surface around the blender. For stubborn residue, mix baking soda and warm water for a deep clean. Once your blender is odor-free, you can enjoy making smoothies and other recipes without any lingering smells.
