Blender leaking black liquid

If you’re a fan of smoothies and shakes, your blender will definitely be your best friend. You put a few ingredients in the blender, run it for a few seconds, and off you go with a healthy drink.

However, the real struggle begins when your favorite blender starts leaking a black liquid. This liquid goes into your food and ruins the whole experience for you – argh!

Blender users often wonder where this dark liquid comes from and is there a way to fix it? This helpful guide will explain the causes of blender leaking problem and a few fixes you can follow right away; read on to know more.

Why is my blender leaking from the bottom?

Blenders start leaking a dark liquid from the bottom when their rubber gaskets are worn down and broken after continuous usage. If your blender is old, its heavily-used rubber gasket may be leaking the liquid into your food. Other reasons that can cause a blender to leak from the bottom are stuck food particulate, rust, and lousy cleaning. Closely monitor your blender’s bottom to see which part is problematic and act accordingly. 

Blenders aren’t designed to work for a lifetime; a time comes when their parts get old, resulting in a lousy performance. If your handy Nutribullet blender has also started releasing a sticky liquid from the bottom, its rubber gasket, shaft, or blades might need replacement. 

Here are a few other reasons that can cause your blender to leak:  

Broken Rubber Gasket 

The rubber gasket holds your blender’s rotatory blade, central shaft, and glass jar together. But regular usage and improper maintenance can erode this rubber gasket over time. If you closely observe your blender’s rubber gasket, you might find small particles coming out of it.

Now, if you run the blender with a faulty rubber gasket, it won’t keep the water and food particles inside the jar. Instead, these particles can seep down to the gasket, resulting in a problematic food leakage. 

Also, even if a rubber ring is okay, its lubricant or oil can leach into your food when not appropriately rubbed. If you have recently repaired your Ninja food blender or Nutribullet, make sure it is not loaded with a lubricant. 

Cracked Blender Jar

If you notice liquid seeping out of your blender jar instead of its bottom, its glass is most likely cracked. These cracks can appear if your glass blender jar falls or collides with a hard surface.

Although the liquid leaking out of the glass jar won’t be as dark as that from the rubber gasket, it can still be very annoying. You can easily spot a crack or broken point in your blender jar by filling it with water and noticing the droplets coming out. 

Rusted Blades

Your blender’s blades can pick up the rust with time and lose their original performance. Regular exposure to water and cleaning detergents can impact metallic blades, eventually making them slower and dirtier. Check its blades if your blender is quite old and you notice a dark liquid leaking from its base.

The presence of a thick layer of rust can be the primary reason you find a dirty liquid in your blended food. Although regular lubrication and careful cleaning can reduce this rust, you might still have to replace these blades. 

Dried Food Particulate 

When you blend something, small and soft food particles can get into the blender’s cracks. Since getting these particles out is quite tough, they keep on accumulating there. A time comes when there’s no space for the food particulate to hide, and it starts getting into your fresh food. 

This stuck food leftover also rots and changes color with time, resulting in a dark seepy liquid. The only way you can ensure there’s no rotten food particulate in your food is by disassembling the blender and cleaning it inside out.

You might have to lubricate or replace the blades because of this stiff food layer. 

Lousy Cleaning 

When was the last time you deep-cleaned your blender? If you can’t remember the date, it’s been quite a while, and it’s about time you do it.

If you quickly pour a cleaning liquid into your blender and rinse it off, it doesn’t guarantee a deep clean. Your blender requires thorough cleaning to perform well and keep your food hygienic. 

Take your blender’s glass jar off its central gasket to check how much cleaning effort is needed. If you find stiff food particulate and rust around the blender shaft, soak it in warm soapy water for 30 minutes.

Clean all parts of your blender after disassembling them and let them air dry before putting them back together. This careful cleaning haul will ensure nothing rotten gets into your food and your blender runs at its full capacity.

How do you fix a leaky blender?

If you have started noticing some dark liquid releasing from your favorite blender, it’s time for some fixing. Although you can’t repair a broken blender, you can do quite a lot for the leaky one.

Here are the two steps to take after you find your blender giving off liquid: 

1. Find Replacements 

If your blender’s jar or gasket is broken, you cannot fix them. To retain your blender’s performance, you must find a good-quality replacement for these parts.

If your blender is under the warranty period, contact its manufacturer to know if replacement parts are available. But if you can’t find these parts’ replacements, getting a new blender might be your final resort.

2. Contact the Blender Manufacturer 

Since some blender manufacturers have a policy to collect broken appliances, you must check with yours to know if this deal is up for grabs. You can send the faulty blender back to the manufacturer or purchase a new one when the existing one is out of order.

How do I stop my blender from leaking?

If your blender is not visibly broken but still starts leaking, you can follow a few quick steps to stop this. Here are some easy tips you can try to stop your blender from leaking: 

Tighten the Glass Jar’s Base

Sometimes the only thing wrong with your blender is its misplaced position. If your blender shakes when on, make sure it’s well snugged around the rubber gasket.   

Replace the Rubber Gasket 

You cannot fix a broken rubber gasket; the only thing doable in this situation is getting a new gasket for your blender. Check if your blender’s rubber ring is hard to repair and act accordingly. 

Fix the Jar 

The cracks in your blender’s jar will only worsen with time. Once you notice these cracks, get a new glass jar because repairing it isn’t possible.

Thoroughly Clean your Blender

Don’t let the food particulate accumulate in your blender’s creaks if you wish to use it without trouble. This stuck-on food gunk will worsen with time, eventually impacting your blender’s performance.

Final Thoughts 

No matter how expensive and advanced your blender is, it can start leaking with time. Sometimes extensive blender usage is the problem, while other times, a broken part is the culprit. But luckily, you can overcome the blender leakage issue by keeping it clean and rust-free. Follow the tips we have shared above and never let food gunk accumulate in your blender to keep that dark liquid from impacting your food.
