How to Get Rid of Plastic Taste From Keurig K Coffee Brewer

I recently bought a Keurig K-Slim Coffee Brewer and was a bit disappointed by the strange rubbery taste that it was producing. I paid $180 for it so I was expecting much more. Granted, any coffee maker will have a plastic taste to it for the first few cups, but just going by the instructions from Keurig, it should be gone after just a few cups.

Anyways, I started researching and looking for other’s that have had the same experience and sure enough, many others in an Amazon discussion are tasting the same thing.

The problem seems to be in the reservoir and the particular plastic that it’s made out of. Some aren’t able to taste it at all, so this might suggest that Keurig is going through different manufacturers who use different materials.

Keurig seems to be aware of the issue and they are reportedly helpful in fixing the problem. They will send you a new reservoir if you are still experiencing problems after cycling the water through multiple times.

Apparently the new reservoir they send out is made of more optimal material. This begs the question – why are they still selling brewers with faulty materials? The problem is ongoing for over a year now, so you’d think they’d fix the problem already. For a $180 coffee maker, funky tasting coffee is not cool…

If you don’t want to go through the hassle of calling up Keurig and waiting for a new reservoir, here’s a good way to get rid of the smell manually:

  1. Remove the reservoir from the Keurig, and fill it with hot water & dish soap.
  2. Let it soak for 30 minutes.
  3. Take a sponge to it and scrub it out thoroughly.
  4. Rinse the reservoir.
  5. Fill it up again with just water and add a 1/2 cup of white distilled vinegar.
  6. Hook it back up to the Keurig.
  7. Cycle through several cups of just water/vinegar until it’s empty (use the largest cup size to speed this up).
  8. Fill it up again with just water (no vinegar) and cycle through the reservoir again.
  9. Repeat step 8 again until the funky taste is gone. It should only take a couple cycles.

The plastic taste that some machines can produce will disappear very quickly when using the espresso machine, the taste of coffee will take over. However, to get rid of this unpleasant taste as soon as possible, you can add lemon juice in the water tank of the machine and let the water run by itself without coffee. For more efficiency, after having made the espresso machine run with lemon, you can incorporate white vinegar.

After doing this I can happily say that the bad taste is completely gone and my coffee is tasting pretty spectacular! Yea, it’s a pain in the butt, but you only have to do it once. It’s definitely worth it. If you still have a plastic or rubbery taste in your coffee after all that, you should contact Keurig and have them send you a new reservoir.

Please leave comments and let me know if this works for you, or if you have any better methods of cleaning it out!

UPDATE

I took advice from one of the comments below and cleaned out my k-dcup holder after I started tasting the plastic again after a couple days. It wasn’t as strong, but it was definitely still there. After soaking the holder in vinegar and washing it thoroughly, the taste seems to be gone again. Hopefully for good this time. Sheesh…what a hassle for a premium coffee maker…
