How To Sharpen Blender Blades? Our Guide Here

Blenders are a great kitchen appliance to have if you like making smoothies, sauces, or soups. The problem is that the blender blades can become dull and inefficient after some time.

Dull blades will cause your food to be chopped up too finely, leaving behind a watery substance rather than chunky goodness.

Luckily there’s an easy way to sharpen the blades: all you need is a few household items!

– A piece of sandpaper

– A butter knife or something with a flat edge that is also wide enough to fit on your blender blades. You could also use the blade side of an old metal bread knife if you have one lying around!

– Something small and sturdy like a can opener, screwdriver, hammer

This is the step in how to sharpen blender blades, as you will be using a variety of different blade sharpening tools depending on the quality of blender you have.

Most blenders, both cheap and expensive, use a sturdy and heavy metal blade. These types of blades can be sharpened on a whetstone, and this method will get the sharpest results.

For high quality blenders, that are made with a lighter metal, the sharpening process requires a much lighter touch.

You may need to use a grinding wheel if the blade is made of aluminum or steel, but these cuts will be much finer, and the blade will have a higher risk of chipping.

Step 1 – Pull the Blender Apart

When you want to sharpen your blender blades, the first thing that you need to do is take it apart. It’s not always an easy process and can be a bit tricky if this is the first time that you’ve taken it apart but with some patience, persistence and luck.

Disassemble your blender carefully, and throughly. Take care not to break any of the inner workings. If your blender is a model with removable blades, be sure to remove the blades before removing the rest of the blender.

Step 2 – Wash the Jug

Once you have taken it apart, fill the jug with warm water and a small amount of soap. You should scrub all the inside parts that were in contact with food to make sure there is no left over residue on any surfaces.

Once everything has been washed out, rinse thoroughly under cold running water for several minutes before drying off completely.

You can wash the jug in the dishwasher, but make sure to remove any food stuck on the blades before you load it in.

If you are washing the blades themselves, make sure they are rinsed very well after you clean them, as food residue left on the blades will cause them to rust and spoil.

Also, be sure to dry the blades completely before you put them back in the jug, to prevent them from rusting.

Step 3 – Remove the Blade

There are a few different ways to remove the blade. You can either take it out from the top, or you can unscrew and remove it from the bottom of the jug.

If you have an older blender that does not come apart at all, try using a screwdriver to pry up one end of the blades while pulling them out

Step 4 – Wash the Blade

The best way to clean the blade is with water. A lot of people think you need harsher chemicals, but that’s not true at all.

If your blades are really dirty or have food residue on them, use a brush and dish soap to scrub off any residual material before washing it in the sink

Steps for Washing Blender Blades: Make sure there is enough water covering the entire blade so it can be washed thoroughly without being damaged.

Using both hands, gently rub one side of each blade against itself while turning around in a circular motion (this will help remove any stubborn dirt).

Gently rinse under running tap-water until most surface grime has disappeared from sight; do this two more times just to make sure

Step 5 – Sharpen the Blade

After you have washed away any grime, use a sharpening stone to sharpen the blade using circular motions. Make sure to run through each side at least ten times before moving on

Gently lay the flat of one side against a sharpening stone and slowly move it back and forth (turning around in a circle). Do this until both sides are cleanly shaved off.

Use water if necessary to keep blades from becoming overheated or too dry during the process. It can take up to 20 minutes depending on how dull your blender blades are; be patient!

You want them as close as possible so they will continue cutting without breaking down foods into smaller bits instead of slicing them right

Caring for Blender Blades

How long do blender blades last, and what’s the best way to care for them? It is a common belief that dull blades can be sharpened; however, this is an old wives’ tale.

In fact, it’s likely that you’re just grinding away at the material, and the chances of success are slim. The most economical way to handle a dull blade is to replace it.

However, you can extend the life of your blades by periodically cleaning them, as well as the inside of your blender.

Lubricant for Blades

Before and after use, you should apply a small amount of cooking oil to the blender blades. This will prevent food from sticking to them as well as help extend their life by preventing oxidation.

Try olive or vegetable oils; these are usually available in your kitchen at home. You can also try baby cream if you have that on hand. Be sure it’s not too cold before applying the lubricant—oil won’t spread properly when too cool!

If any material sticks to the blades, remove it with a tissue paper towel soaked in vegetable oil or an old toothbrush dipped in dish soap (be sure to rinse thoroughly!). Do this before reassembling your blender again; then turn on low speed.

Last Words

Blender blades are very vulnerable to damage. The most common reason for damaged blender blades is a lack of maintenance, but you can also damage them if you don’t use a little common sense in how you use them.
