How to Sharpen Mixer Jar Blades at Home: Easy Salt Trick That Works

How to Sharpen Mixer Jar Blades at Home: A mixer grinder is one of the most essential kitchen appliances in Indian households. From grinding spices to making smoothies, chutneys, and batters, it handles multiple tasks every day with ease. However, after prolonged use, many people notice that their mixer grinder does not perform as efficiently as it once did.
Grinding becomes slower, spices remain coarse, and the mixer starts making more noise than usual. In such situations, most people consider buying a new jar or even replacing the mixer altogether. But the truth is, you can sharpen mixer jar blades at home using a simple, cost-effective method—without spending extra money.
Why Do Mixer Jar Blades Become Dull?
Over time, mixer blades lose their sharpness due to:
-
Regular grinding of hard spices and grains
-
Wear and tear caused by friction
-
Lack of proper cleaning and maintenance
Dull blades not only reduce grinding efficiency but also put extra strain on the motor, increasing noise and electricity consumption.
Can Mixer Jar Blades Be Sharpened at Home?
Yes, mixer jar blades can be sharpened at home to a certain extent. While professional sharpening is required for severely damaged blades, minor dullness can be easily fixed using a household ingredient—salt.
How Salt Helps Sharpen Mixer Blades
It may sound surprising, but salt works as a natural abrasive. The coarse particles of salt create gentle friction when they come in contact with the blades. This controlled friction helps remove minor bluntness and restores the blade’s cutting edge.
The best part is that this method:
-
Requires no special tools
-
Is safe when done correctly
-
Is inexpensive and quick
How to Sharpen Mixer Jar Blades Using Salt
Follow these simple steps carefully:
Step 1: Clean and Dry the Jar
Wash the mixer jar thoroughly to remove any food residue. Allow it to dry completely. Moisture can reduce the effectiveness of this method.
Step 2: Add Salt
Add one handful or about half a cup of coarse salt into the jar. If coarse salt is not available, regular table salt can also be used, though coarse salt gives better results.
Step 3: Run the Mixer
Close the lid properly and run the mixer:
-
Use pulse mode if available
-
Run for 1–2 minutes in short intervals
Pulsing helps distribute salt evenly and prevents overheating.
Step 4: Empty and Clean
After grinding, discard the salt. Wash the jar thoroughly to remove all salt particles and dry it before use.
Additional Tips for Better Results
-
Do not add water while sharpening
-
Avoid running the mixer continuously for long durations
-
Repeat this process once every few months for maintenance
-
This method works best for slightly dull blades, not broken ones
When Should You Avoid This Method?
Do not use this trick if:
-
The blade is chipped or broken
-
The jar makes burning smells
-
The mixer vibrates excessively
In such cases, professional servicing or blade replacement is recommended.
How to Maintain Mixer Blades for Long Life
-
Clean the jar immediately after use
-
Avoid grinding extremely hard ingredients frequently
-
Use pulse mode for tough items
-
Dry the jar completely before storage
Proper maintenance keeps blades sharp and improves the overall lifespan of the mixer.
Before spending money on a new mixer jar or appliance, try this simple salt sharpening trick. It is an easy, budget-friendly way to restore blade performance and improve grinding efficiency. With just a little care and regular maintenance, your mixer grinder can work like new for a long time.
