How to Clean Mixer Grinder Jar at Home Without Damage: Complete Indian Kitchen Guide

The mixer grinder is the most used appliance in every Indian kitchen. From grinding coconut chutney at 6 AM to making masala paste for dinner, it runs multiple times every single day. And because it handles everything — wet coconut, turmeric, tamarind, dried spices, tomatoes, and onions — the jars take the worst beating of any kitchen appliance you own.

The result: stained jars that turn yellow from turmeric, jars that smell of onion even after washing, blades that feel sticky and dull, and lids that become impossible to remove cleanly. Most people scrub hard, damage the jar, or simply replace it long before necessary.

You do not need to do any of that. This guide shows you how to clean every part of your mixer grinder jar properly — without scratching the polycarbonate, without damaging the blade assembly, and without spending a single rupee on special cleaning products. Works for Preethi, Butterfly, Sujata, Philips, Bajaj, and all other brands.

✅ Quick Answer (In Short)

• Self-cleaning method: fill jar halfway with warm water and a drop of dish soap, run for 30 seconds — does 80% of the cleaning instantly
• Remove turmeric stains with baking soda paste or a few drops of lemon juice left for 10 minutes
• Never submerge the blade assembly in water — water enters the bearing and causes rust
• Remove the rubber gasket from the jar lid after every use and wash separately
• Dry all parts completely before reassembling — moisture in the bearing ruins the blade over time

Why Mixer Grinder Jars Get Damaged So Fast in Indian Kitchens

Indian cooking asks a lot from the mixer grinder. We grind wet coconut, fibrous ginger-garlic paste, thick tomato puree, hard dried spices like pepper and cumin, and heavily pigmented ingredients like turmeric and red chillies. Each of these creates a different kind of damage:

Turmeric and red chilli leave deep yellow and orange stains that penetrate the polycarbonate plastic of the jar. These are not surface stains — the pigment actually enters the plastic.

Coconut and onion leave oils and compounds that create persistent smell even after the jar looks clean. The smell lives in microscopic scratches in the jar surface.

Tamarind and tomatoes are acidic and degrade both the rubber gasket on the jar lid and the blade assembly rubber over time — the same effect as on a pressure cooker gasket.

Hard spices like whole pepper, dried red chillies, and cardamom create fine scratches on the inside of polycarbonate jars every time they are ground. These scratches accumulate and cause the jar to look permanently cloudy or dirty even when clean.

Understanding these causes helps you clean correctly — because each type of damage needs a different solution.

The Parts of a Mixer Grinder Jar You Must Clean Separately

Most people wash the jar as one unit. This is the most common mistake. Each part needs different treatment:

Step-by-Step: How to Clean Mixer Grinder Jar Without Damage

Step 1 — Use the Self-Cleaning Method First

This is the fastest and most effective first step — and most Indian households do not know it.

Immediately after grinding, while the jar is still wet:

1. Fill the jar halfway with warm water
2. Add two to three drops of dish soap (Vim, Pril, or any brand)
3. Lock the jar onto the mixer grinder body
4. Run at medium speed for 20 to 30 seconds
5. Pour out the soapy water and rinse with clean water

This self-cleaning action removes 80 percent of all food residue instantly — including wet coconut, tomato, and onion. The spinning blades create a vortex that cleans all inner surfaces including around and under the blade where your hand cannot reach.

Do this step immediately after use, before the food residue dries. Dried residue is ten times harder to remove than fresh residue.

Step 2 — Wash the Jar Body by Hand

After the self-clean step, wash the jar by hand with warm water and dish soap using a soft sponge. Always use the soft side of the sponge — the rough green side of a Scotch-Brite creates scratches in polycarbonate that cloud the jar permanently.

Pay attention to the threading at the bottom of the jar where it screws onto the base — food residue collects in these threads and creates hygiene problems and smell over time. Use an old toothbrush to clean these threads thoroughly.

Never put a mixer grinder jar in a dishwasher. The high heat and harsh dishwasher detergent degrades polycarbonate rapidly, causes the jar to become permanently cloudy, and damages the blade assembly rubber.

Step 3 — Remove and Clean the Rubber Gasket Separately

The rubber gasket sits inside the jar lid and creates the seal. After every use, remove it from the lid groove and wash it separately with cool water and mild soap.

The gasket is the most neglected part of the mixer jar — and the biggest source of smell. Food particles, oil, and moisture get trapped between the gasket and the lid. If not cleaned and dried properly after every use, mould grows here within days, especially during monsoon.

After washing, dry the gasket completely and refit it in the lid groove before storage. Check it every month for cracks or permanent deformation — a damaged gasket on a mixer jar is a safety risk as it can cause the jar to leak or the lid to come off under pressure.

Step 4 — Clean the Blade Assembly Without Submerging

This is the most critical step for extending the life of your mixer grinder. The blade assembly — the metal blade with its rubber seal and bearing that screws into the bottom of the jar — must never be fully submerged in water.

Water that enters the bearing causes rust within weeks. A rusted bearing makes the blade wobble, creates noise, and eventually seizes completely — requiring blade replacement which costs ₹200 to ₹500 depending on brand and jar size.

The correct way to clean the blade:

1. Unscrew the blade assembly from the jar
2. Hold it under running water briefly from the top — do not let the bottom (bearing side) sit in water
3. Use a toothbrush to clean around the blade edge and the rubber seal
4. Shake off excess water and wipe dry with a cloth immediately
5. Leave it to air dry completely before reassembling — 15 to 20 minutes minimum

Step 5 — Remove Turmeric and Spice Stains

Turmeric stains are the nemesis of every Indian mixer jar. Here are three methods that actually work:

Method 1 — Baking Soda Paste (Best for most stains) Make a thick paste of baking soda and water. Apply it to the stained areas inside the jar. Leave for 15 to 20 minutes. Scrub gently with a soft sponge. Rinse clean. Repeat if needed for very old stains.

Method 2 — Lemon Juice (Best for yellow turmeric stains) Squeeze half a lemon inside the stained jar. Add a tablespoon of salt. Run the mixer for 15 seconds with this mixture inside. Leave for 10 minutes. Rinse clean. The citric acid in lemon breaks down turmeric pigment effectively.

Method 3 — Sunlight (The forgotten method) Place the clean, washed jar in direct sunlight for 2 to 3 hours. UV rays from sunlight naturally bleach polycarbonate and break down turmeric and chilli pigments. This is the oldest trick from Indian grandmothers — and it genuinely works for stains that cleaning cannot remove completely. No cost, no chemicals, no effort.

Step 6 — Remove Onion and Coconut Smell

Smell that persists after washing is one of the most common complaints with mixer jars. Two methods:

Baking soda soak: Fill the jar with warm water, add two tablespoons of baking soda, leave for 30 minutes, then rinse. Baking soda neutralises the sulphur compounds that cause onion smell.

Vinegar rinse: Add two tablespoons of white vinegar to the jar, fill halfway with water, run the self-clean cycle for 30 seconds, then rinse thoroughly with clean water. Vinegar eliminates both smell and bacteria simultaneously.

After either method, leave the jar open to air for at least one hour before storage.

From My Experience: What Works in Indian Kitchens

Written by Chinnagounder Thiruvenkatam, veteran of 25 years service across India and founder of dailyhindnews.in/.

A mixer grinder was one of the first major kitchen investments in every home I lived in during my years of service. Moving frequently across different states meant packing and unpacking the same mixer, adapting to different water qualities, and making it last as long as possible.

The self-cleaning method was something I learned from a colleague’s wife in Tamil Nadu — she ran the mixer with soapy water after every single use without exception. Her mixer jars were spotless and smell-free after years of use. I adopted this habit immediately and have followed it ever since.

The biggest mistake I saw consistently: people washing the blade assembly under running water and leaving it to dry while assembled. Water sits in the bearing, rust develops inside where you cannot see it, and within six months the blade starts making a grinding noise. By then the bearing is already damaged. Disassemble, wipe dry, and reassemble only when fully dry — this extends blade life by years.

On turmeric stains: in South Indian kitchens where fresh turmeric is ground frequently, the sunlight method is the most practical. Leave the jar in the window or on the terrace for an afternoon. The yellowing clears significantly without any effort.

Mistakes That Damage Mixer Grinder Jars

• Submerging the blade assembly in water — ruins the bearing, causes rust and wobble
• Using the rough side of a sponge — creates permanent cloudiness in polycarbonate
• Putting jars in the dishwasher — damages polycarbonate and blade rubber permanently
• Not cleaning immediately after use — dried residue is far harder to remove and causes smell
• Ignoring the rubber gasket — primary source of mould and food smell
• Grinding without enough liquid — dry grinding overheats the jar and blade, degrades rubber faster
• Leaving the jar assembled during storage — moisture gets trapped, promotes rust and smell
• Using harsh acid cleaners — degrades polycarbonate and blade rubber significantly

How to Store Mixer Grinder Jars Correctly

Storage is as important as cleaning for jar longevity:

• Store jars disassembled — jar body, blade, lid, and gasket stored separately
• Never store with the lid tightly closed — traps moisture and causes smell
• Store in a dry, ventilated spot — not inside a closed cabinet immediately after washing
• If storing for extended periods, apply a tiny amount of coconut oil to the blade threads to prevent seizing

Always buy brand-matched replacement parts. A Preethi blade in a Butterfly jar will not fit correctly and creates safety risks during operation.

FAQ: Mixer Grinder Jar Cleaning in Indian Kitchens

Q: How do I remove turmeric stains from a mixer grinder jar completely?

A: Use a combination of three approaches for best results. First, apply baking soda paste and leave for 20 minutes, then scrub with a soft sponge. If stains remain, rub lemon juice with salt and leave for 10 minutes before rinsing. Finally, place the cleaned jar in direct sunlight for 2 to 3 hours — UV light breaks down turmeric pigment naturally. Repeating this process over two to three days removes even old, deep-set turmeric stains from polycarbonate jars.

Q: Why does my mixer grinder jar smell of onion even after washing?

A: Onion smell comes from sulphur compounds that penetrate microscopic scratches in polycarbonate. Washing with soap alone does not eliminate it. Fill the jar with warm water and two tablespoons of baking soda, leave for 30 minutes, then rinse. Alternatively, run the self-clean cycle with white vinegar and water, then leave the jar open to air for one hour. Repeat if the smell persists — very old smell may need two or three treatments.

Q: Can I wash the mixer grinder blade in the dishwasher?

A: No — never put the blade assembly in a dishwasher. The high-temperature water and harsh dishwasher detergent degrade the rubber seal around the blade and cause the bearing to rust. Always wash the blade assembly by hand, keeping the bearing side away from water, and dry immediately and completely before reassembly.

Q: My Preethi mixer jar has become permanently cloudy inside. How do I fix it?

A: Permanent cloudiness in polycarbonate is usually caused by fine scratches from rough scrubbers or dishwasher use, or by hard water mineral deposits. For mineral deposits: fill the jar with a mixture of equal parts white vinegar and water, leave for one hour, then scrub with a soft sponge. For scratch-related cloudiness: this cannot be fully reversed, but the sunlight method and baking soda paste improve appearance. Prevent future cloudiness by only using the soft side of sponges.

Q: How do I clean the three-jar mixer grinder — which jar should I prioritise?

A: Clean all jars after every use using the self-clean method — this takes only 2 minutes per jar. For the chutney jar (smallest jar), clean with special attention as coconut and tamarind residue builds up quickly in the narrow interior. The dry grinding jar needs particular care — remove all spice dust with a dry brush first, then do the self-clean cycle. Never run the dry grinding jar with water until all dry spice residue is removed first.

Q: Is it safe to use a mixer grinder jar if the lid gasket is cracked?

A: No — a cracked lid gasket is a safety risk during operation. The gasket creates the pressure seal that prevents the lid from coming off while the blades are spinning. A cracked or missing gasket can cause the lid to release suddenly, which is dangerous. Replace the gasket immediately — it costs only ₹30 to ₹80 and takes two minutes to replace.

Q: My mixer jar blade has started making a rattling sound. What does this mean?

A: A rattling sound from the blade usually indicates a loose or damaged bearing — typically caused by water entering the blade assembly during cleaning. First, check that the blade assembly is screwed tightly into the jar. If tightening does not fix the rattle, unscrew the blade and inspect the bearing for rust or damage. A damaged blade assembly should be replaced promptly — a faulty blade creates vibration stress on the mixer motor and can cause the jar to crack during operation.

Conclusion

Your mixer grinder jar does not need harsh chemicals, expensive cleaners, or frequent replacement. The self-clean method after every use, gentle hand washing with cool water, keeping the blade assembly dry, and the occasional baking soda or lemon treatment for stains — these four habits keep your jars clean, smell-free, and functioning like new for years.

Start with the self-clean method today — immediately after your next grinding session. Two minutes of effort right after use saves you thirty minutes of hard scrubbing later. Your jars will last twice as long, and your kitchen will smell fresher every day.
