How to Clean Mixer Grinder Jars Properly (Without Damaging Blades)

MaintenanceBy BestMixerGrinder Editorial Team·April 15, 2026·6 min read

Most mixer grinder problems — bad smells, leaking jars, dull blades — come down to one thing: improper cleaning. Indian kitchens are tough on jars. Turmeric stains, coconut residue, and wet batter all leave behind deposits that corrode the blade assembly over time. The good news? A proper cleaning routine takes less than 2 minutes a day and can add years to your mixer's life.

Daily Cleaning Method

The fastest and most effective daily clean is the self-clean method. Do this immediately after use — before residue dries and hardens.

1Fill the jar halfway with warm water (not boiling — thermal shock can crack the jar base).
2Add 2–3 drops of dish soap.
3Lock the jar onto the motor base and run on medium speed for 10–15 seconds.
4Pour out the soapy water, rinse with clean water, and repeat once.
5Invert the jar on a clean cloth to air-dry. Never store with the lid on — trapped moisture breeds bacteria and causes smell.

Pro tip: For the dry masala jar, skip water entirely. Wipe with a dry cloth, then grind a small piece of stale bread or a tablespoon of raw rice to absorb residual spice oils before the water rinse.

Weekly Deep Clean

Once a week, disassemble the jar completely for a thorough clean. This prevents gasket degradation and blade corrosion.

1. Unscrew the blade assembly

Turn counter-clockwise (most brands). Use a rubber grip cloth if it's tight — never use metal tools.

2. Remove the rubber gasket

Peel it out carefully. Check for cracks or hardening. Soak in warm soapy water for 5 minutes.

3. Clean the blade assembly

Use an old toothbrush to scrub around the blade base where food collects. Rinse thoroughly.

4. Clean the jar interior

Use a bottle brush with dish soap. Pay attention to the bottom corners where residue accumulates.

5. Dry everything separately

Air-dry all parts for at least 30 minutes before reassembling. Moisture trapped under the gasket causes leaks.

6. Wipe the motor base

Use a damp cloth on the motor base. Never submerge it in water. Clean the coupler socket with a dry brush.

Removing Turmeric Stains

Turmeric (haldi) contains curcumin — a powerful natural dye that bonds to stainless steel and plastic. Regular dish soap won't touch it. Here are three methods that actually work:

Baking Soda + Lemon Paste

20 min

Mix 2 tbsp baking soda with fresh lemon juice to form a paste. Apply to stained areas, leave for 20 minutes, scrub with a soft brush, rinse. Works on both stainless steel and plastic lids.

White Vinegar Soak

30 min

Fill the jar with equal parts white vinegar and water. Let soak for 30 minutes. The acetic acid breaks down curcumin bonds. Rinse thoroughly — vinegar smell disappears after drying.

Sunlight Method

2–3 hours

After washing, place the stained jar or lid in direct sunlight for 2–3 hours. UV rays naturally bleach curcumin. This works surprisingly well on plastic lids and is completely chemical-free.

Removing Bad Smell from Jars

Smell in mixer jars comes from two sources: bacterial growth (from storing jars with lids on while damp) and absorbed spice oils in the gasket. Here's how to fix both:

For bacterial smell:

Fill the jar with warm water + 1 tsp baking soda. Run for 15 seconds. Rinse. Then fill with water + 1 tbsp white vinegar, run again, rinse. The baking soda neutralises acids; the vinegar kills bacteria.

For spice oil smell in gasket:

Remove the gasket and soak in a mixture of warm water + 2 tbsp baking soda for 1 hour. If the smell persists after 2–3 treatments, replace the gasket — they're inexpensive (₹30–80) and available on Amazon.

Blade Maintenance

Mixer grinder blades are made from hardened stainless steel and don't need sharpening — they work by impact and friction, not cutting. What they do need is protection from rust and corrosion.

✓Always dry blades completely before storage — even a thin film of moisture causes rust within 48 hours in humid Indian climates.
✓After the weekly deep clean, apply a tiny drop of food-grade coconut oil to the blade shaft (not the blade edges) to prevent oxidation.
✓Never grind extremely hard items like frozen meat or whole nutmeg — this bends the blade tips and causes vibration.
✓If you notice the blade wobbling or the jar vibrating more than usual, the blade assembly needs replacement, not sharpening.

What NOT to Do

✗ Soak jars in water overnight

Water seeps into the blade assembly and causes rust and gasket swelling.

✗ Use steel wool or abrasive scrubbers

Scratches the stainless steel surface, creating grooves where bacteria hide.

✗ Put jars in the dishwasher

High heat warps plastic lids and degrades the rubber gasket rapidly.

✗ Store with the lid on

Traps moisture inside, causing bacterial growth and persistent bad smell.

✗ Use bleach or harsh chemicals

Corrodes the blade assembly and leaves toxic residue that contaminates food.

✗ Grind without liquid in wet jar

Running the wet grinding jar dry overheats the blade and warps the gasket.

When to Replace Jars

Even with perfect maintenance, jars have a lifespan. Here are the signs it's time to replace rather than repair:

⚠ Leaking from the bottom

Replace gasket first (₹30–80). If leaking continues, replace the blade assembly (₹150–300). If still leaking, replace the jar.

⚠ Visible cracks in the jar body

Replace immediately. Cracks can cause the jar to shatter during operation — a serious safety hazard.

⚠ Blade wobbles or grinds unevenly

Replace the blade assembly. Don't attempt to straighten bent blades at home.

⚠ Permanent staining despite cleaning

Cosmetic issue only — safe to continue using. Replace when other functional issues appear.
