Need to know how to sharpen blender blades?
Many homes today can’t do without a blender in the kitchen. Without this kitchen gadget, people can not use fruits and vegetables to enjoy fresh, safe, and yummy drink concoctions.
Raw food dieters have discovered that their blenders are vital to food preparation. You can make delicious milkshakes in an instant in all your favorite flavors, and during your get-together, you can comfortably serve them to family and friends.
Like other kitchen appliances, though, they are likely to get worn out when people use them regularly and after a long time. Do you know how to sharpen blender blades when they go dull?
The blender blades will become dull after too much grinding, pureeing, and crushing. You will start to notice that your blender is not performing as well as it used to. The most obvious sign is a change in texture.
Finding replacement blades or buying a new blender is the first thing that can come to your mind. However, If you can do anything to sharpen those blades, it will save you more cash. You’ll have to do some maintenance to keep your blender blades robust.
You may have to sharpen the blades, depending on what kind of blender you have and the materials from which the blades are made. Doing this alone, though, can be dangerous as the edges are sharp and can cause injuries quickly.
If you’re concerned about the process of sharpening the blender blades and your warranty doesn’t cover blade sharpening or replacement parts, we’ll walk you through the process.
Caring for Blender Blades
To clean your blender blades, remove the blender jar from the motor base by lifting the jar up and down. Please turn off the locking ring and separate it from the rubber gasket and the cutting ring according to your manufacturer’s instructions.
Wash the cutting assembly in warm soapy water, rinse thoroughly and dry thoroughly.
For most blenders, the lock ring can be washed in the top rack of the dishwasher or washed with warm soapy water.
For blenders that do not have a removable blade, immediately after use, fill the blender jar with 1/3 hot water and a drop or two of the detergent. Put the lid on the blender and run for about 10 seconds at medium speed.
Then rinse the blender with fresh water, using a sponge to remove any remaining residue from the blade or inside the jar.

As such, with proper cleaning and care, your blender blades should last the life of your appliance.

Five Steps To Sharpen Your Blender Blades
In keeping with the spirit of the KISS principle (Keep It Simple Sharpeners), we have our easy-to-follow 5-step process to make it easy for you.
1. Identify Your Blender Type and Determine How You Can Disassemble it
There are different models and types of blenders, some of which do not allow you to separate the pieces.
If you can’t separate the blades from the container, you may not be able to sharpen the blades on your own. If this is the case, we recommend that you buy a new blender or contact the company to see if they can help you solve your problem or help you with the replacement parts.
If you can disassemble the blender, start doing so after you unplug the device, as this can help prevent injury. From there, you’re going to want to separate each section. Although we do not recommend unscrewing any part of the blender because this can lead to damage.
2. Wash Each Section Carefully
It’s best to always work with a clean blender since the cleaner the blender, the less likely it would run into problems. Residue from sticky foods makes it harder to sharpen and can cause your hand to slip and cut while working.
First, remove the blender and wash each section that can be placed in the water. This is likely to include the glass container, the blade section, and the lid.
The motor can be easily wiped off with a damp paper towel or, at most, used with a bit of soap before wiping it dry. But it is recommended to be cleaned with a sanitary wipe.
The blades are the main section you’re going to work with. Therefore, inspect every nook and cranny to get all the dirt and grime out.
After each section has been cleaned, pat dry with a clean kitchen cloth or paper towel.

3. Remove the Blades and Wash them Again
We have now reached the dangerous part of sharpening the blades.
You’ll see the blades attached to the base of the device. You will want to inspect the base thoroughly and see if they can twist out of the bottom. If they can’t, you will not be able to sharpen your blades.
If possible, you’ll want to carefully twist them counterclockwise to help separate the blades from the base. Using protective gloves or even cooking mitts can help prevent injury. Don’t hold your bare hands on the blades, as you can seriously hurt yourself.
After separating the two, you should have the base of the device, the protective ring or seal, and the blades. All of these parts should be separated from the bottom. Handle these carefully and place everything carefully on a folded towel.
After separating the blades, you’ll have to wash them under the blade section. Food residues may remain from months to years of use. It would be best to be very careful when cleaning this section as you want to use a minimum amount of soap and rinse your blades.
Once they’re clean enough, you can start sharpening your blades.
4. Sharpen Blender Blades
Once the blades are dry, place the sharpest side of the blade away from your body and on top of the sharpening stone. From here, start running against the sharpening stone, holding the blade at a slight angle and moving it away from your body.
When you have run it many times around the stone’s face, turn it over and repeat the same process on the opposite side. There should be about four sides to sharpen each blender blade. Two of them are in the back of the blades and two are in the front of the blades. However, it will depend very much on what kind of make and model you have. Repeat the procedure for all the blades, either way, until each side has a sharp edge.
When the blades are sharpened, you can easily tell, as they will have a slight glint on them and appear to be sharper. Don’t be tempted to use your hand to touch the edges, because if they are sharpened, they can easily be cut. We recommend waiting for the blender to be assembled and tested to see if the blades are really sharpened.
5. Put Everything Back Together
Now that you’ve sharpened your blades, it’s time to put it all back together. Return the protective ring to the blender’s base and screw it into the blades. Ensure that everything is locked in place before the glass container is attached and secured back to the blender motor.
Once everything is in place, you can do a test run by trying to make a simple smoothie or a chopped vegetable. If the blades work efficiently, then you’ve finished the process of sharpening the blender blades. However, if they still seem dull, we suggest you repeat the process until you get the desired results.
Are There Any Possible Complications?
Not all blenders can be taken apart, as we have said. Most high-tech blenders or recent models will allow you to separate each section. However, lower-grade blenders are usually stuck together and won’t come apart.
If you can’t sharpen your blades, the company you bought your blender from may be in a position to assist you. Contact their customer support; sometimes, you can get replacement parts or a new blender if the warranty covers it.
Conclusion
As you can see, sharpening your blender blades is daunting and dangerous.
We do not recommend this process if you’re uncomfortable working with sharp objects. If you haven’t used a sharpening stone before, we suggest you get help from someone who does.
However, for those who are not intimidated by this process and are careful, these five simple steps show you how to sharpen blender blades and extend the life of your blender’s performance.
