Easily Descale Keurig Costco Brewing Systems

General Cleaning

Care and feeding of a Keurig coffee maker is pretty straightforward and only requires a few minutes of your time every few weeks. Setting aside just a little time on a regular basis to clean and descale Keurig machines will provide years of trouble-free brewing and great tasting coffee from your Costco Keurig brewer.

Regular cleaning will ensure that your Keurig brewing system lasts a long time and produces consistently good coffee in every cup. Although you don’t have to descale Keurig machines very often, you should consider descaling Keurig every 3 or 4 months to maintain best taste and brewing performance.

The outside of your Costco Keurig brewing system can be cleaned with a damp, non-abrasive cloth or sponge and optionally a gentle soap or detergent like dish soap. However, make sure you never immerse or hold your Keurig brewer under water or get liquid into or near any of the electronic components. Also, never get cleaners or chemicals into the or near the removable water reservoir.

When brewing flavored coffees, hot chocolate, or iced tea, you should always remove these Keurig pods immediately after brewing. It’s also best to then perform a cleansing brew to ensure that the pod holder is clear of flavoring and residue.

The K-Cup Holder, funnel, drip plate and drip tray on your Costco Keurig brewing system are dishwasher safe, but the water reservoir and removable lid are not dishwasher safe, so make sure to clean them by hand!

Cleaning the Keurig K-Cup Holder

  1. Remove the K-Cup assembly by opening the cover and pushing up on the bottom of the assembly until it releases. The K-Cup holder is dishwasher safe.
  2. Remove and clean the funnel by pulling on it until it snaps off. The funnel is also dishwasher safe. To replace it, just snap it back into the K-Cup holder.
  3. Remove and clean the exit needle located on the inside bottom of the K-Cup holder. You can clean the needle using a paper clip or similar tool. Insert the paper clip into the tube and move it around to loosen and remove any clogs or debris. You will not be able to poke all the way through the needle because the other opening is located on the side and not the top.
  4. After cleaning, align the K-Cup holder tabs with the opening by placing the two front tabs on the bottom and the single tab on top and snap it into place by pushing down on the top rim.

How to Descale Keurig Coffee Makers

Scale, which is a buildup of lime and calcium from your water, is harmless, but it can alter the taste and performance of your brewing system. The buildup can make it harder to heat the brewing water to the necessary temperature, and can also impart a taste in the resulting cup of joe. To avoid this, you should descale Keurig machines whenever the brewing process slows down or your coffee begins to taste different.

Descaling Keurig coffee makers on a regular basis will help maintain the heating element and water reservoir. Using filtered water to brew coffee and tea with will also help reduce the amount of scale so you won’t have to descale Keurig machines as often.

Although Keurig recommends descaling Keurig brewers every 6 months, we’ve found that if we descale Keurig and thoroughly clean the Keurig accessories every 3 − 4 months, our coffee brews faster and tastes better;

Keurig coffee brewers are very easy to use, and it’s just as easy to descale Keurig coffee machines.  Some Keurig coffee makers even flash a warning light to let you know descaling is needed. In fact, descaling Keurig machines requires only a little white vinegar (or a commercial solution like Dezcal Descaler) and about a half an hour of your time. We prefer white vinegar because it’s cheap and readily available, but the Dezcal Descale Keurig product is also nontoxic and biodegradable.

In either case, both white vinegar and Dezcal Descaler will dissolve lime scale, calcium and other buildup inside your Keurig coffee maker.

Here’s what you’ll need to descale Keurig Costco models:

  • 48 ounces of undiluted white vinegar
  • Large ceramic mug (do not use a paper cup)


  1. Empty the water in the Water Reservoir.
  2. Disable “Auto Off” features.


  1. Pour approximately 48 ounces of the vinegar into the water reservoir.
  2. Place the ceramic mug on the drip tray and run a full brew cycle without any keurig pods! Just press the brew button. Pour the contents of the mug into the sink.
  3. Repeat the brew process without a K-Cup until ADD WATER lights up.
  4. Let the Brewer stand for at least 4 hours while still on.
  5. Discard any left over vinegar and rinse the water reservoir thoroughly.


  1. Fill the water reservoir with fresh water.
  2. Place the ceramic mug back on the drip tray and run another brew cycle. Pour the contents of the mug into the sink.
  3. Repeat the brew process until you see ADD WATER, then refill the water reservoir with fresh water and repeat the rinse process a second time.
  4. If DE-SCALE is still displayed after completing the procedure, repeat the entire descaling procedure above.
