How to Clean a Portable Blender: Blade, Lid & Deep Clean

By Saran Reddy, Founder — InstaCuppa | April 9, 2026 | 5 min read | Last updated: 30 September 2026. Steps checked against our product page that day.

Here is how to clean a portable blender: wash it right after every use with warm water, one drop of soap and one short blend. It takes less than a minute. It is the best thing you can do to keep your blender working well for years. In this guide, you will learn the daily wash, how to remove the blade, what can go in the dishwasher, the weekly deep clean, storage tips, and how to get rid of a bad smell.

How Do You Wash a Portable Blender After Every Use?

This is the habit that matters most. In the 2013 NSF International Household Germ Study, the blender gasket was the 3rd germiest of 14 kitchen items tested. Swabs from blender gaskets carried Salmonella, E. coli, yeast and mold. NSF says a blender must be taken apart, with the gasket pulled out, to be cleaned well. A quick wash after each use stops food from drying in the first place.

Here is what I do every single time:

1. Empty the jar completely. Pour out any leftover smoothie.
2. Fill the jar about halfway with warm (not boiling) tap water.
3. Add one small drop of liquid dish soap.
4. Attach the lid, press the button, and run one blend cycle (about 20 seconds).
5. Pour out the soapy water.
6. Rinse under running water for 5 seconds.
7. Shake off excess water and leave the lid off to air dry.

That is it for daily care. No sponge is needed. This is the same routine our product page gives for the InstaCuppa Portable Blender Bottle (450 ml). Once a week, take the parts apart for the deep clean below.

How Do You Remove the Blade from a Portable Blender?

Banana, mango pulp and protein powder are the usual culprits. If the daily wash did not catch everything, a 10-minute soak loosens dried bits. Other brands may not let the blade come off, so check your manual first. Never open the motor housing or the battery part. Our product page says this voids the warranty.

Step-by-step:

1. Fill a bowl with warm water and add a drop of dish soap.
2. Submerge the blade assembly (just the blending base, not the motor unit) for 10 minutes.
3. Use a narrow bottle brush to reach around the blades.
4. Rinse thoroughly and shake dry.

Important: Never use a metal scourer or steel wool on the blades. The InstaCuppa blades are 304 food-grade stainless steel. A soft nylon brush works best. A small baby bottle brush is the right size for this job.

Can You Put a Portable Blender in the Dishwasher?

This question comes up a lot. The safe answer for any brand is simple: hand-wash it. It takes about two minutes.

Here is why:

• The motor unit holds a rechargeable battery and the electronics. Never put it under water or in a dishwasher. Wipe it with a damp cloth, and clean the charging port gently with a dry cloth.
• The jar on the InstaCuppa blender is BPA-free, food-grade ABS plastic. Our product page allows the top rack, but it warns that high dishwasher heat and harsh detergent can wear the rubber seals over time.
• The gasket (rubber seal) is the part to protect. Hand-wash it. BlendJet's user guide says never to put its base, jar or lid in a dishwasher, or put it fully under water.

Hand washing takes two minutes. A dishwasher takes an hour and can wear the seals. For most people, hand washing is the better choice.

How Do You Deep Clean Weekly?

The weekly deep clean takes about five minutes. A fixed day, such as Sunday morning, makes it easy to remember.

Here is the process:

1. Add warm water to the jar (halfway).
2. Add 1 tablespoon of baking soda.
3. Blend for one cycle (about 20 seconds).
4. Let it sit for 5 minutes.
5. Pour out, rinse thoroughly.
6. For white water spots, blend warm water with half a lemon (or 1 tablespoon of white vinegar) as a separate step. Do not mix it with the baking soda: they fizz and cancel each other out.
7. Remove the silicone gasket from the lid. Rinse it separately. Check for any discolouration or cracking.

Why take the gasket out? It is the part NSF flagged. In the NSF study, only a blender that was taken apart, with the gasket pulled away from the base, could be cleaned well. Dry every part fully, mainly the threads and the seal, before you put it back together.

Why Does My Portable Blender Smell Bad?

If your blender smells sour or musty, it is almost always one of these:

1. Protein residue around the blade. Whey protein and milk stick to blade crevices and start smelling within hours. The fix: soak the blade assembly in warm water + baking soda for 15 minutes, then scrub with a bottle brush.
2. Wet storage with the lid on. Sealing a damp blender creates a warm, dark, moist environment — perfect for bacteria. The fix: always store with the lid off.
3. Old gasket. Rubber seals can hold on to smells over time. If the deep clean does not remove the smell, ask the seller or brand for a new gasket before you buy a new blender.

Wet storage is the easiest one to fix. Leave the lid off after cleaning until every part is dry.

How Should You Store a Portable Blender?

Storage is the step most people skip, and it is the reason most blenders start smelling.

My storage routine:

• After rinsing, I shake the jar upside down 3–4 times to get water out of the blade area.
• I place the jar upright on my kitchen counter with the lid off.
• The motor base goes next to it, standing upright.
• I never store it in a drawer or cabinet until both parts are completely dry (usually takes 30–45 minutes in Indian weather).
• If travelling, I wrap the jar in a dry cloth and keep the lid loose in my bag.

Keep it out of direct sun and away from heat, such as a sunny window or the top of the microwave. Charge it only when the base is dry.

Frequently Asked Questions

Can I use hot water to clean my portable blender?

Use warm water, not boiling water. Very hot water can harm the plastic jar and the rubber seal. BlendJet also says to use warm, not hot, water.

How often should I replace the silicone gasket?

Check it every week during the deep clean. Replace it when it looks cracked, hard or stained, or still smells after a deep clean. There is no fixed month count; how often you blend matters most.

Is it safe to blend soap and water inside the blender?

Yes. One drop of liquid dish soap in warm water is safe. Both our product page and BlendJet's guide give this as the daily wash. The spinning water reaches most of the jar and blade. Rinse well afterwards so no soap taste is left.

Can I use vinegar instead of lemon for the deep clean?

Yes. One tablespoon of white vinegar works the same way as lemon juice. Both are mild acids that dissolve mineral deposits and neutralise odours.

What if my blender still smells after deep cleaning?

The gasket is likely the problem. Remove it, soak it in a baking soda solution overnight, and check for cracks. If the smell stays, ask the seller or brand for a new gasket.
