Black Substance Coming Out Of My Blender


Nobody wants their nutritious food to be tainted with minuscule pieces of non-food material that have been generated by the blender itself. It’s common to see in blenders like Nutribullet, Vitamix, etc. a black liquid substance coming out of a blender.

It not only annoys but also emerges lots of questions to mind. In this article I have tried to cover all the necessary questions for you so, you may not worry about the black substance coming out of the blender anymore.

What is this black substance coming out of the blender?

This black substance is usually a blend of the lubricants required to smooth or grease the moving elements of the machine, as well as the blended substance. A leaky gasket, which has a tight seal on its blades, might cause the black or grey substance in some circumstances.

The tiny black flakes are made up of material that can be found in the seal directly beneath the blades. When the blades turn, the rotating assembly of the blades is supposed to create friction by rubbing against the seal that is directly under those blades. The purpose of the seal is to prevent any liquid from escaping through the container’s seams.

How to clean it?

Once you have finished using a blender, it is best to clean it by filling the container with warm water, turning the blender on for about 30 seconds, and then rinsing it. Do not store the container with the base and cover on at the same time because this will cause the agitator to corrode from the moisture that is trapped inside.

What factors are responsible for producing a black substance from the blender?

There could be multiple factors that can be the reason for producing it.

  • Your Rubber gasket might damage

When it comes to things wearing out in a blender, one of the first things to go is the rubber gasket. It does not matter how much money you spend on it or what kind of premium brand you choose to invest in. It is inevitable that a rubber gasket will become damaged over time because of the natural wear and tear that occurs over time.

Because this is a piece of rubber, there is no real way to fix it, and no one else is going to do it for you either. Rather than cleaning it, you should consider changing it out because rubber gaskets are readily available and not very expensive.

  • Your blender is older now

Because nothing in this world is permanent, age-related problems are guaranteed to occur at some point in life. The fact that the blender is dripping with a dark liquid is almost always an indication that it is getting on in years.

In practice, regardless of whether you are blending very soft foods (such as mangoes) or harder things, some of the food remnants are most likely getting into the internals – most commonly, between the bearing and the shaft. This is the case regardless of whether you are blending very soft foods or harder things.

  • Food decomposition

The food that has been blended but is still stuck in there will eventually fall into the blender. It is likely that there is additional material in there that has become black as a result of the natural decomposition process.

After the addition of the new food, the mixture becomes much darker in overall appearance. The introduction of new foods invariably results in the demise of older ones. As a direct result of this, the black leftovers will leak under the blender, and the disgusting black food that you keep seeing is a result of this.

When noticing the black substance, you should invert the blender so that you can observe the fine black coat that has most likely already formed. It is a little bit too late by the time these leftovers make their way out.

  • Not cleaning your blender properly

Neglecting the importance of a blender’s hygiene can also be the reason for producing black substances. You can avoid the problem, by giving it a thorough cleaning. Take some liquid dish soap, combine it with some water, and then put the mixture through the blender.

Start the blender and let it run for about a minute. It should then be drained out, and the process should be repeated with clean water. If there are still bubbles visible in the water after you have finished rinsing, you should probably give it another go with some clean water.

As a result of the fact that many of the blades can be removed, this component can also be taken apart and everything underneath can be cleaned.

  • Shaft needs attention

Be sure to keep an eye on the shaft as well. Placing a string around the shaft and moving it in a left-to-right motion will help you remove stale and rigid chunks of food. After completing any of the cleaning steps, you should always give everything a final rinsing with some clean water.

If you choose to actually disassemble some of the components, be sure to thoroughly dry them first. If the shaft seems to be moving too slowly or too stiffly, all you need to do is lubricate it with a non-hazardous spray or solution. To make sure it actually enters, you should do it from the bottom up.

  • Your jar is leaking

People have a tendency to ignore cracks in the glass, despite the fact that these are some of the most common issues out there. When people see a leak coming from the blender, they immediately point their finger at its internal components, particularly the rubber gasket. The vast majority of them are unaware that jars can also become cracked or damaged, which is quite typical if you have a habit of dropping things. There is a lower probability that you will notice this crack right away. You won’t be able to tell that there is a crack in your shake if you consume it as soon as it is finished being made.

How can you be sure that broken glass is the source of the leak? Make an effort to discover where it came from. If the leak is coming from the top of the jar rather than the basket, then the jar most likely has a crack in it.

How to know, if the black substance is mixing with the food as well or not?

A black liquid gives the impression that it contains more than just water because it is visually distinct from clear liquids. In addition, you probably imagine that all of those liquids could be easily pushed into your smoothies. This is a disturbing thought which might worry you a lot. For this, I have found a technique to check whether that black or grey substance is mixing with the food as well or not.

  1. Take half a liter of filtered water to a bowl that is clean.
  2. After that, transfer the water to a suspicious
  3. Run the blender on high for a total of 2
  4. Pour the water into the white bowl after running.
  5. You would be able to see either the black specks in the bowl or not.
  6. If yes, then you need to fix it immediately.

By this technique, you are able to determine whether or not the food you eat contains black specks that are produced by your blender. You can determine whether or not your blender is contributing the unwelcome component to your dish by performing the test with the water and the white bowl.

How to know your blender is being under attack?

By observing your blender for a set of diagnostic symptoms, you may easily and unmistakably tell when it is coming under attack.

  • If the moving parts of your blender, such as the electric motor or the blades, are not adequately lubricated, your blender is going to become excessively noisy when you use it. This is because of the friction that is created. In these kinds of circumstances, the blender is also likely to become a little bit too hot to touch because of the heat it generates.
  • Another typical issue with blenders is the leaking of liquid, which is especially likely to occur if you do not leave enough room in the blender cup for air to circulate, which is necessary for the appropriate grinding of ingredients.
  • It is possible for the power base of the blender to become unsteady and noisy if it is not screwed on with sufficient force during the assembly process.If you do not follow the directions that come with the blender when you are using it, you will probably experience other problems as well, such as the blades rusting more quickly than they should.

When should you clean your blender?

In order to maintain proper hygiene, the blender must always be cleaned before being used. By doing this, you will have the peace of mind of knowing that you are indeed maintaining it in good condition as you should be.

It is very simple to determine whether or not you need to clean your blender. For example, you should clean it when it appears dirty or when there are visible signs of stuck and dried blended debris on the blades or other parts of the blender.

It is essential to clean your blender after it has been used frequently for a significant number of times, regardless of whether or not it appears to be dirty.

How do I clean the black gunk in the blades of a blender?

After you have completed blending your beverage, soup, or other food items, refill the blender jar with warm water, place the jar back on the base, and turn the blender on for a few seconds. If the component you were combining contains a lot of oil, you should add some soap to this method first, then follow it up with some clean water.

You should never keep liquids in your blender, and you should also never leave the blending assembly and cover on the jar when the blender is not in use.

When it is possible for the contents of the jar to remain dry, I remove the blending assembly from the base and place it inside the jar. Never put the blending assembly in the dishwasher because doing so will remove the lubrication that keeps it functioning properly.


When you need some ingredients to be reduced to smaller sizes or ground, a blender comes in very handy. This is true whether you are preparing a drink or a meal.

Blenders can be found on the market in a wide variety of sizes, brands, and models, from which you can select the one that best suits your needs. If you treat them with care and perform routine maintenance on them, you can ensure that they will last for a very long time.
