How to Clean a Blender: Quick Methods Including the Self-Cleaning Trick

Blenders are one of the most-used kitchen appliances — and one of the trickiest to clean thanks to those sharp blades. But with the right technique, you can have a spotless blender in under a minute. Here are the best methods, from the quick self-clean trick to a thorough deep clean.

Method 1: The Self-Cleaning Trick (30 Seconds)

This is the fastest way to clean a blender after everyday use — no disassembly required.

1. Immediately after use, fill the blender jar halfway with warm water.
2. Add 2-3 drops of dish soap.
3. Put the lid on and blend on high for 30-60 seconds.
4. Pour out the soapy water, rinse with clean water, and blend again for 10 seconds to rinse.
5. Pour out and air dry upside down.

This method works perfectly for smoothies, sauces, and most everyday blending tasks. The spinning blades create a vortex that cleans all interior surfaces.

Method 2: Hand Wash (For a Thorough Clean)

For sticky, thick residue or when the self-clean method isn't enough:

1. Disassemble the blender — remove the jar from the base, and unscrew the blade assembly from the bottom of the jar (if removable).
2. Wash each part separately in warm soapy water.
3. Use a long bottle brush to clean inside the jar, reaching the bottom around the blade.
4. Use a small brush or old toothbrush to clean around the blade assembly and gasket.
5. Be careful with the blades — always handle by the blade assembly, not the blade edges.
6. Rinse all parts thoroughly and air dry completely before reassembling.

Method 3: Baking Soda for Odors and Stains

For blenders that smell like garlic, onion, or fish after blending strong ingredients:

1. Fill the jar halfway with warm water.
2. Add 1 tablespoon of baking soda and a few drops of dish soap.
3. Blend on high for 60 seconds.
4. Let sit for 5 minutes, then rinse thoroughly.

Method 4: Vinegar Soak for Mineral Deposits

If your blender jar has cloudy mineral deposits from hard water:

1. Fill the jar with equal parts white vinegar and water.
2. Let soak for 30 minutes.
3. Blend briefly, then rinse thoroughly.
4. Wipe with a microfiber cloth for a streak-free finish.

Cleaning the Blender Base

Never submerge the motor base in water.

1. Wipe the exterior with a damp microfiber cloth.
2. For sticky residue around the base where the jar sits, use a damp cloth with a little dish soap.
3. Dry immediately — don't let water sit near the motor vents.

Can You Put a Blender in the Dishwasher?

Many blender jars are dishwasher-safe (top rack only) — check your manual. The blade assembly is usually dishwasher-safe too, but hand washing is gentler and extends blade life. Never put the motor base in the dishwasher.

Tips for Keeping Your Blender Clean

• Clean immediately after use — dried smoothie or sauce is much harder to remove.
• Use the self-cleaning method after every use for quick maintenance.
• Do a full hand wash weekly or whenever you blend strong-smelling ingredients.
• Check the gasket/seal regularly for mold — it's a common spot that gets overlooked.

Frequently Asked Questions

What is the easiest way to clean a blender?

The self-cleaning method — fill with warm soapy water and blend for 30-60 seconds. It cleans the jar and blades in under a minute with no disassembly.

How do I remove stains from a blender jar?

For turmeric or berry stains, fill with warm water and 1 tablespoon of baking soda. Blend and let sit for 10 minutes before rinsing. Sunlight also helps fade stains in clear plastic jars.

How do I clean blender blades safely?

Always handle the blade assembly by the plastic housing, not the blade edges. Use a brush to clean around the blades rather than your fingers. A bottle brush lets you clean around the blades without touching them.

Why does my blender smell bad?

Residue trapped under the blade assembly or in the gasket is usually the cause. Disassemble fully, clean the gasket and blade assembly thoroughly, and use the baking soda method to neutralize odors.
