How to Clean a Mixer Grinder Jar Properly — Remove Stains, Odours & Turmeric Marks

A mixer grinder that isn't cleaned properly after every use will smell of the previous session's masala, stain permanently with turmeric, and eventually develop blade corrosion from trapped food residue. These are avoidable.

The cleaning method matters as much as the frequency. This guide covers the correct daily cleaning routine, how to remove turmeric stains and spice odours, and the deep cleaning process for jars that haven't been cleaned properly for a while.

Daily Cleaning Routine — After Every Use

1. Rinse the jar immediately after use. Dried food residue from masala, coconut, or batter becomes significantly harder to remove after 15-20 minutes. Even a quick rinse under running water immediately after use removes most residue.

2.  Fill the jar half-full with warm water and 2-3 drops of dish soap. Place the jar back on the motor base, close the lid, and run for 10-15 seconds. This self-cleaning method removes the blade assembly's residue that a sponge cannot reach.

3. Pour out the soapy water, rinse with clean water, and run with plain water for another 5 seconds to flush.

4. Remove the jar and wash the inside with a soft sponge. Pay attention to the rubber gasket around the blade assembly — food traps here and is a common source of odour.

5. Dry the jar completely before reassembling. Never store jars with moisture trapped in the blade assembly — this causes rust on the blade shaft over time.

How to Remove Turmeric Stains from Mixer Grinder Jars

Method 1 — White Vinegar Soak

Mix 1 part white vinegar with 2 parts water. Fill the stained jar with this solution and let it soak for 10-15 minutes. The acetic acid in vinegar breaks down the curcumin compound responsible for turmeric's yellow stain. Wash with dish soap after soaking. For severe staining, repeat twice.

Method 2 — Lemon Juice and Baking Soda

Make a paste of baking soda and fresh lemon juice. Apply to the stained surface with a soft sponge. Let it sit for 5 minutes. The mild abrasive action of baking soda and the citric acid from lemon lift the turmeric deposit. Rinse thoroughly. This method is safe for both plastic and stainless steel jars.

Method 3 — Dish Soap and Sunlight

Apply dish soap directly to the stained area and place the jar in direct sunlight for 2-3 hours. UV light breaks down turmeric's colour compounds naturally. Rinse and wash after sun exposure. This is the gentlest method and works well for mild staining on polycarbonate transparent jars.

How to Remove Spice Odour from Mixer Jars

•  Rice grinding: add 2-3 tablespoons of uncooked rice to the dry jar. Run for 20-30 seconds. Rice is a natural absorbent that pulls spice oils from the jar surface. Empty and rinse.

•  Baking soda paste: apply a thin paste of baking soda and water to the interior. Leave for 15 minutes. Rinse. Baking soda neutralises acidic spice compounds that create lingering odours.

•  Lemon peel grinding: add a few pieces of lemon peel to the jar with water and run for 15 seconds. The lemon oil replaces the spice odour and leaves a clean neutral scent.

•  Bread grinding: grind a piece of dry bread. Like rice, bread absorbs oils and odours effectively. Good for clearing strong fenugreek or asafoetida smells.

Deep Cleaning — For Heavily Soiled Jars

Disassembling the Blade Assembly

On most Wonderchef mixer grinders, the blade assembly can be removed from the jar by unscrewing anticlockwise. This allows direct cleaning of the blade shaft, the rubber gasket, and the inner surfaces that the self-cleaning method cannot reach. Important: unplug the mixer before disassembling any part.

Cleaning the Blade

Hold the blade by the central hub, never by the cutting edges. Wash with warm soapy water and a bottle brush to remove residue from under and around the blade. Dry completely before reassembly. A blade that is not dried properly develops surface rust, which affects both appearance and hygiene. 

Cleaning the Motor Body

Wipe the motor body with a soft damp cloth. Pay attention to the jar coupling area where food sometimes splashes during overfilled grinding sessions. Never spray water directly on the motor body or submerge it. The vents on the motor should be kept clear of accumulated dust — a dry brush or compressed air removes dust effectively.

Wonderchef Mixer Grinders with Easy-Clean Jar Design

Frequently Asked Questions

How do I clean a mixer grinder jar after grinding turmeric?

Immediately rinse the jar. Then soak in diluted white vinegar (1:2 with water) for 10 minutes. Alternatively, apply lemon juice and baking soda paste, let sit for 5 minutes, scrub gently, and rinse. For polycarbonate jars, direct sunlight for 2-3 hours after applying dish soap helps fade the stain naturally. 

How do I remove the smell of fenugreek or garlic from a mixer jar?

Grind 2-3 tablespoons of uncooked rice for 20-30 seconds — this absorbs the oils responsible for the smell. Alternatively, grind a paste of baking soda and water, leave 15 minutes, and rinse. For strong garlic smell, lemon peel grinding works well.

Can I put mixer grinder jars in a dishwasher?

Stainless steel jars are generally dishwasher safe, but hand washing is recommended to preserve the blade assembly's rubber gasket. The dishwasher's high heat can degrade the gasket over time, leading to leaks. Polycarbonate transparent jars should not go in the dishwasher — the heat causes cloudiness and weakening.

How often should I deep clean my mixer grinder?

Daily light cleaning after every use, and one deep clean (disassembling the blade assembly) every 1-2 weeks depending on frequency of use. If you grind strong-smelling ingredients like fenugreek, garlic, or asafoetida frequently, deep clean weekly.

My mixer jar leaks — what should I check?

The most common cause is a worn or improperly seated rubber gasket. Remove the blade assembly and check the gasket for cracks or deformation. If the gasket is worn, replace it — Wonderchef service centres stock replacement gaskets for all models. Also check that the jar is properly locked onto the motor base before grinding.

Conclusion

A clean mixer grinder works better and lasts longer. The daily 10-second soapy water self-clean after every use prevents 90% of the staining and odour issues. For turmeric stains, vinegar or lemon-baking soda works consistently. For odours, rice grinding absorbs what washing misses.

Stainless steel jars like those in the Robo, Capri, Vietri, and Acura range are significantly easier to maintain than plastic jars.
