Rusty NutriBullet? Learn Why It Rusts and How to Fix It

My beloved NutriBullet has been my faithful sidekick for years, helping me whip up smoothies and salad dressings in seconds. But lately, I’ve noticed some rust spots on the blade and in the cracks of the cup. At first, I tried to ignore it, but now I’m worried that my trusty Nutribullet won’t last much longer if I don’t take action. And I thought about it a little.

I have noticed that this popular blender tends to rust over time and with frequent use, for a few reasons. The good news is that my simple solutions help remove existing rust and prevent more from forming, which I’ll tell you about below.

So, if your Nutribullet shows signs of rust, don’t despair. Here’s what you need to know to get it back in working order and keep it going strong for years. Let’s start!

First of all, I will explain why your Nutribullet blender rusted.

5 Reasons Your Nutribullet Blender Rusted

As an avid Nutribullet user and kitchen expert, I was disappointed when I noticed rust stains on my blender. Several factors contribute to Nutribullet blender rust. I am mentioning some of the reasons below:

5 Reasons Your Nutribullet Blender Rusted

Moisture buildup

The biggest culprit is moisture buildup in the base and blade assembly. Tiny water droplets left behind after washing can lead to rust if not fully dried. Now, I make sure to thoroughly dry all parts after cleaning, especially the blade and gasket area.

Harsh detergents

Another reason could be the use of harsh detergents with bleach or ammonia. They can break down the protective finish and expose the metal underneath. I’ve switched to a natural, bleach-free dish soap, which is gentler and helps prevent rust.

Scratches on the finish

Even small scratches or dents in the finish allow moisture and oxygen to reach bare metal parts. Think of small scratches or dents in your blender’s finish as little doors for moisture and oxygen. Although they are small, they allow the metal to reach inside these troublemakers. It’s like a sneak attack. You’ll be surprised to know that moisture and oxygen from the air combine, and before you know it, they begin to rust metal parts. Even minor scratches can cause rust problems for your blender. No matter how innocent they may seem. When assembling or cleaning my NutriBullet, I handle all parts with care to avoid damaging the finish.

Acidic Ingredients

  • Acidic ingredients, like citrus fruits (lemons, oranges), tomatoes, and vinegar, can corrode metal over time.
  • When these ingredients come into contact with the blades or other metal components of the blender, they may speed up corrosion.

Salty Ingredients

  • Salt, especially if it is not cleaned off promptly, can contribute to corrosion on metal surfaces.
  • If salty ingredients are frequently used in the blender, and the appliance is not cleaned thoroughly, it may lead to rusting over time.

Storing in a humid environment

Excessive heat and humidity can speed up rust formation. Store your NutriBullet in a cool, dry spot away from direct heat sources like ovens or dishwashers.

Nutribullet blenders rust due to the reasons above, so avoid these reasons. Do you know how dangerous rust is? Let us inform you about this.

Why is Rust So Dangerous?

Rust is dangerous news for your NutriBullet. As the owner of a NutriBullet myself, I’ve had to deal with rust before. Here’s why it’s bad and what you can do:

Rust contaminates your smoothies and meals. When rust forms inside the NutriBullet cup or blade, it flakes off into your drinks and food. Ingesting rust can lead to anything from an upset stomach to serious health issues. It can harbor tetanus bacteria. It can cause serious illness and even death if it enters a wound. Staying up-to-date on tetanus vaccinations is important. This is especially true before handling rusty objects.

Rust also damages the blades and cups over time. As rust eats away at the metal, your NutriBullet components become less effective and efficient. The blades get dull, and the cups become prone to leaks. Eventually, they’ll need replacements.

Regarding rust, the US Environmental Protection Agency (EPA) advises against inhaling large amounts of rust, as it can cause respiratory problems. Iron oxide, a safe, FDA-approved food coloring, is used to rust foods, but in small amounts, it may not harm health. Source

Now that you know the dangers of rust, you will know how to remove it from your blender. 

How to remove rust from blender blades?

Below, I’m showing rust removal techniques.

How to remove rust from blender blades

Using Baking Soda

Baking soda is very effective in removing rust. I made a thick paste from baking soda and water and used an old toothbrush to scrub the rust off each blender blade. Baking soda is non-toxic and gentle enough to remove rust from blade surfaces.

However, you can now apply the paste to the rusted area on the blender blade. Then, let sit for 15-20 minutes to allow the baking soda to break down the rust. Then, use a toothbrush and scrub well. When done, rinse the blades with water and dry them completely.

Using WD-40

I’ve used WD-40 to fix rust and lubricate parts on all kinds of appliances over the years. For my NutriBullet, it’s been a lifesaver. Those sharp blades whirling around at high speeds can start to show spots of rust over time. This can happen, especially if you don’t always completely dry the container after washing. Not to worry. A little WD-40 will have your NutriBullet parts rust-free and running smoothly again in no time.

Here’s what I do:

Disassemble my NutriBullet into its main parts like the blades, seals, and drive socket.

Clean all parts with soap and water, then dry completely with another towel. Make sure no moisture remains before moving on to the next step.

Shake the can of WD-40 well. Hold each part over the towel and spray a light, even coat of lubricant over all surfaces. Pay extra attention to any visibly rusty spots.

Let the WD-40 soak in for a few minutes. Then use a clean cloth to wipe away any excess, buffing the parts to a shine.

• Reassemble your NutriBullet, and you’re ready to blend!

Using Vinegar

Using white vinegar is an easy way to remove rust from the blades and container of your NutriBullet. Vinegar is a mild acid that helps dissolve the rust and leaves behind a protective coating to prevent future rust.

Any remaining rust spots got a vinegar treatment. I filled a resealable plastic bag about halfway with white vinegar and dipped the blender blades into the bag. After soaking them overnight, I removed the blades in the morning. Then I washed them and dried them with a clean cloth. The acid in the vinegar helps break down the rust and keeps the metal shiny and rust-free.

So, you fill a small bowl with white vinegar. Next, soak the rusty blender blades in vinegar for 1-2 hours (I soaked them overnight, though, because I was a little queasy). Then, remove the blades and wipe off the rust with a soft cloth. Rinse the blades under running water and dry them thoroughly before reassembling them.

Using chemicals like Metal Glo.

Using harsh chemicals to clean the NutriBullet can damage the finish and cause rust. Instead, I prefer to use Metal Glo, a natural metal polish and rust remover.

How Metal Glo Works

Metal Glo is a gentle abrasive polish made of fine pumice powder suspended in a wax and oil base. When you rub it on rust or tarnish with a soft cloth, the pumice physically buffs away the rust and oxidation. The wax and oils then form a protective coating to prevent future rust.

Unlike harsh chemicals, Metal Glo won’t strip or damage the NutriBullet’s finish. It’s safe for all metals – stainless steel, aluminum, copper, brass, and more. I’ve used it for years to polish and protect metal items in my home, and it works great for keeping my NutriBullet looking like new.

To use Metal Glo, apply a small amount with a soft cloth. Gently rub in small circles over any rust spots on your NutriBullet. Buff until the rust is removed and you see the bare, shiny metal underneath. Then, wipe away any excess with a clean cloth. Your NutriBullet will be rust-free and protected. It will be ready to make your favorite smoothies and juices for years.

Hopefully, from the above discussion, I have been able to explain to you how I remove rust. You just follow the steps I gave above.
