How to Clean Your Blender Quickly and Easily

How to clean your blender

If you’re not taking apart your blender every time you clean it, it may not be as clean as you think.

How clean is your blender? Even for those neat freaks out there, it’s probably not as clean as you think.

I probably shouldn’t share my dirty secret, but after years of using the same blender, I recently discovered that I wasn’t cleaning it properly, or as thoroughly, as I should have been. I’ll spare you the details, but the bottom line is this: just because something LOOKS clean doesn’t always mean that it is clean.

The problem was in the impeller assembly. The what? The impeller assembly is a vital part of your blender. It is the base of the blender jar that houses the blades—basically what makes your blender blend. Typically, this base is removable, and it’s removable for a very important reason—because it needs to be cleaned.

Even if you don’t see food getting trapped beneath the blades, you still might not be cleaning the assembly completely. Between the base and the blade is a rubber gasket. After repetitive use and washing, this gasket becomes a magnet for mold. That’s right—the moisture gets trapped between the blade and the base of your blender jar and makes it the ideal breeding ground for bacteria and mold. Yuck!

Clean your blender after every use

Fortunately, the solution is easy, and you probably already have all of the supplies in your kitchen. Rinse the blender jar, then pour in 1/2 cup of water and 1/3 cup of baking soda. Run the blender for 30 seconds, then disassemble it and wash all of the parts in warm soapy water. Check your manual to find out if you can toss the parts into the dishwasher. Just remember not to submerge the motorized base in any water. Instead, periodically clean it with a damp, but not saturated, sponge and an old toothbrush for those hard-to-reach crevices and grooves.

It’s just as important to remember to thoroughly air dry or towel dry the parts before reassembling the blender jar. Remember to follow this procedure to disassemble the blade housing and wash it after every use, and you’ll never have a problem with mold or germs in your blender again.

    My mother always took the blender apart after every use, so I figured everyone did! Ick!

    I was told by an appliance repair shop not to place the impeller or the gasket in the dishwasher. The heat and extended immersion in water will remove the lubricant from the bearings in the impeller.and cause the gasket to wear out prematurely.
