Get Rid Of Plastic Taste From Your Keurig With These Easy Ways?

Rid Of Plastic Taste

Keurig machines are great, but they have a significant flaw.

Its plastic pieces touch the water, and over time this causes a plastic taste to seep into your cup. 

This article will guide you on how to get the plastic taste out of your Keurig so you can enjoy the coffee from the machine-like before.

Plastic, as you may already be aware, is harmful to your health. Furthermore, two types of chemicals are used to manufacture plastics to harden the basic plastic layer. These compounds, known as Bisphenol-A (BPA) or Phthalates, cause the plastic taste in your coffee.

The recycled grade 7 water reservoir in the coffee machine also emits BPA. On the other hand, PVC is the main element in the manufacturing of phthalate, which is used in coffee makers.

 A Keurig coffee maker’s plastic aftertaste is generated by hot water coming into contact with the coffeemaker’s plastic components.

The contact can extract trace volumes of "off-gas" from the coffeemaker's production line, imparting a distinct flavour to the water.

Almost all Keurig’s inner parts are composed of plastic, including the K-cup. Mineral deposition in the water, even in older equipment, can affect the taste of the coffee and add to that plastic taste or odour. 

Look for BPA-free parts in a coffee maker if you don't want your coffee to taste like plastic. Aside from that, if your coffee maker has a plastic taste, you must now clean it at home using the methods below.

How to clean Keurig thoroughly?

The simplest way to remove the plastic flavour from a Keurig is to clean all of the separate pieces regularly and descale the inside workings as needed.

If the plastic taste persists, use a reusable metal K-cup filled with ground coffee to eliminate one point of contact with plastic.

It is a matter of personal preference. Wash the  Keurig’s exterior once a week to avoid clogging the inside or interfering with the electrical workings. You can do so with a damp cloth or a wet paper towel. 

Here are some easy ways to clean the inner workings of the Keurig. 

Solution 1: Run vinegar through your Keurig

How long do you let vinegar sit in Keurig?

Vinegar is a mild acid and will neutralize any off-tastes in the Keurig. 

The vinegar solution will clean the inside of your Keurig, removing sludge, tea stains, and stale coffee residue.  

It will also remove calcium deposits and hard water scale. You can easily get it at home improvement stores or a local grocery store.

What to do:

  • Add 48 ounces of white vinegar to the water reservoir. Fill the Keurig reservoir with vinegar until it is empty.
  • Dump the used vinegar down the drain while the coffee machine is running.
  • Keep the Keurig on for at least 4 hours once the reservoir is depleted. Turn off the “Auto Off” option if your version has one.
  • After that, the water reservoir can be removed, washed, and replaced with fresh water.
  • Run the water through the Keurig without a K-cup multiple times until the water no longer smells like vinegar when it comes out of the machine.

Solution 2: Run Hot water through the machine

It includes using the Keurig without the K-cup, which can aid in mineral removal. I appreciate that this “solution” appears unsuccessful, yet other people have reported success with it on the internet. 

Can you run a washer with just hot water?

What to do:

  • Fill the Keurig’s water reservoir, then run it continually until the reservoir is empty.
  • Examine the water coming from the Keurig to see if it has picked up any coffee grounds that may have become stuck in the system.
  • Keep the Keurig running until the water is clear.
  • Instead of using a K-cup, run many brew cycles to empty at least one or two full clean water reservoirs through the machine.

Solution 3: Run food-grade activated charcoal

Activated charcoal is a substance made from burned, crushed, treated wood. There are various grades of activated charcoal, but the lower grades are often less expensive. 

Many people have found success with activated charcoal to remove odours and tastes from stainless steel appliances. 

What to do:

  • To begin, clean your water reservoir well with warm, soapy water.
  • You should thoroughly clean it, both inside and out, and thoroughly rinsed. In any case, this is something you should do regularly.
  • Remove the water filter made of charcoal from the system. It may be paradoxical to use a charcoal filter to remove the charcoal from your water.
  • Fill the reservoir with warm water until the “fill” line is reached.
  • Add approximately 3/4 teaspoon of activated charcoal to the water.
  • Set your Keurig to the LOWEST temperature setting if it has one. According to search engines, increasing the water’s temperature can diminish activated charcoal’s efficiency (adsorption rate).
  • Run enough brew cycles to deplete the reservoir (without the K-cup).
  • After passing the water through the device, test it.
  • Continue the charcoal water rinse if necessary.

Solution 4: Use Reusable Stainless Steel K-cup

Drinking coffee from a reusable stainless steel K-cup eliminates one point of contact with plastic instead of an aluminium K-cup.

Can you use reusable cups in Keurig?
It decreases the chance of aluminium leaching into your drink and increases your reusable coffee container's quality and lifespan. 

The stainless steel K-cup will not affect the taste of your coffee, aroma, or your health. However, it is not dishwasher safe.


Running the Keurig without K-cup multiple times in a row may be the best way to go. The water will wash away any mineral deposits and, hopefully, leave your Keurig with no taste of plastic. 

Of course, the brewer should be given fresh water every once in a while, but it's probably easiest to just run it without cups or K-cups until the taste is gone. Then, it will eliminate plastic contact and give you better-tasting coffee.
