Can you put blender blade in dishwasher?


Many people own and use blenders regularly in their kitchens. Blenders have removable blades that need to be cleaned after each use. This leads to the common question – can you put blender blades in the dishwasher? The short answer is yes, you can put most blender blades in the dishwasher. However, there are a few caveats to keep in mind. In this article, we’ll discuss in detail if and how to clean blender blades in the dishwasher.

The Basics of Dishwasher Safe Blender Blades

Most blender blade assemblies are top-rack dishwasher safe. This includes commonly used blender brands like Vitamix, Ninja, NutriBullet, Oster, Hamilton Beach, KitchenAid, and Cuisinart.

Blender blades are made from sturdy stainless steel. This material can withstand the high heat, detergents, and water pressure of a dishwasher cycle.

However, there are a few exceptions. Some blender models have blades made from plastic rather than metal. Plastic blender blades are not dishwasher safe as they can warp or melt under high heat.

Also, some high-performance blenders like Vitamix or Blendtec have blades tightly fastened to the blender jar. These are not designed to be removable and submerged in water.

So as a general rule of thumb, if your blender has a removable stainless steel blade assembly, it is likely dishwasher safe. Check your blender’s manual to confirm.

Precautions for Washing Blender Blades in Dishwasher

While you can wash most blender blades in the dishwasher, you need to take some precautions:

1. Remove any silicone gaskets

Many blender blades have a silicone gasket fitted to the base. This helps create a tighter seal between the blade and the blender jar. Silicone gaskets should always be removed before putting the blades in the dishwasher. The high heat can damage and dislodge the gasket.

2. Place blades carefully on top rack

Position the blades horizontally on the top rack, away from other utensils. Make sure no parts are hanging off the edge or loosely placed. The spinning water jets can potentially cause the blades to move and damage other items or the dishwasher interior.

3. Use caution when unloading

Blender blades come out extremely sharp and hot after a dishwasher cycle. Always handle them carefully, preferably with thick gloves to avoid cuts.

4. Inspect blender gasket after washing

After removing blender blades from the dishwasher, inspect the gasket. Make sure it is still intact and properly fitted before reattaching the blades. Replace gaskets that become damaged or loose.

5. Avoid detergents with bleach

Bleach and other harsh chemicals found in some dishwasher detergents can cause pitting and corrosion on stainless steel over time. For long term blade care, use milder detergents.

Tips for Effective Blender Blade Cleaning

Follow these tips for safely and effectively cleaning blender blades in the dishwasher:

  • Rinse blender blades immediately after use to remove leftover food residue.
  • Wash the blender jar separately before disassembling blades.
  • Place blades loosely on top rack, without stacking or overlapping.
  • Run a hot wash and dry cycle for thorough sanitization.
  • If needed, use a nylon brush to remove stubborn stains beforehand.
  • Let blades air dry completely before storing to prevent rusting.
  • Replace blender gaskets that become loose, cracked or stained.

Avoid these common mistakes when washing blender blades:

  • Leaving blended food or liquids to dry on the blades.
  • Overloading blades on top rack of dishwasher.
  • Using ultra-harsh dishwasher detergent or bleach.
  • Letting blades sit wet after washing.
  • Putting plastic blender blades in the dishwasher.

Cleaning Blender Blades by Hand

While the dishwasher is convenient, you can also hand wash blender blades effectively:

Supplies Needed:

  • Mild dish soap
  • Warm water
  • Clean sponge or nylon brush
  • Soft towel for drying

Steps for Hand Washing Blender Blades:

  1. Disconnect blade assembly from blender jar.
  2. Rinse blender and blades under running water.
  3. Fill sink or bowl with warm water and mild detergent.
  4. Soak blades for 15 minutes, use brush to remove stains.
  5. Rinse blades thoroughly under water.
  6. Dry immediately with a soft lint-free towel.
  7. Polish with soft cloth if needed.
  8. Reattach blades to blender jar once fully dry.

Hand washing allows extra care when cleaning crevices and corner of the blades. Avoid using any abrasive scrubbers than can damage the blade finish. Also take precautions while handling the sharp edges.

Signs Your Blender Blades Need Replacement

With regular cleaning, blender blades can last for years. However, inspect your blender blades periodically for any signs of wear and tear. Here are some indications your blender blades need replacing:

  • Corrosion or rust spots on stainless steel
  • Visible cracks, dents or pitting of blade

  • Damage to rubber gasket around blade
  • Plastic housing has cracks or stains
  • Blades feel dull, leave large chunks after blending
  • Leaking around base of blade while in use
