How to clean a Keurig coffee maker

Keurig owners tend to clean their machines in two most popular methods, general method- using soap and dish detergent- which should be done regularly, and using vinegar- which should be some two to four times every year, up to your frequency of using the machine. My honest article today will show you how to perform these two methods correctly.


Method 1: General Cleaning

This method covers some steps as follow:

Uninstall the machine: Lift the handle and take out the inside K-cup holder to open the machine’s cover.

  • To take out the K-Cup holder, use one hand to hold the top of the part while using the other hand to press the bottom of the K-cup assembly, make sure that the assembly should be released in the end
  • As you remove the K-Cup holder, remember that the two sharp needles inside can hurt you if you haphazardly take out the assembly
  • The rest pieces should be disassembled gently and gradually. Smoothly pull the funnel on til it is away from the K-Cup holder. Then disassemble the drip tray by taking it out from the base of the machine

Clean the machine’s parts: K-Cup holder, drip tray, funnel, as well as drip plate: Luckily, these parts are all dishwasher-safe. So simply put them in the top rack of the dishwasher and have the brewer run under standard wash setting, using mild dish detergent.

  • If you want to hand-wash the K-Cup holder, rinse it with warm to hot running water. Further scrubbing or detergent is not required here but you should be careful or you will easily get stabbed due to the sharp needle in the holder
  • If you want, you can also hand-wash the other parts: funnel, drip plate, and drip tray. Simply put them under hot soapy water, then gently use a non-abrasive cloth to scrub them. Finish the process by careful rinsing to eliminate soap residue
  • Yeah, turn back with your dishwasher cleaning. As you finish cleaning the parts, remember to dry them all well. You can choose to let them air dry within some hours, or dry them manually, using a clean dish towel or paper towels

Clean the needle: Exit needles are designed at two places, inside bottom and higher parts of the K-Cup holder. Each needle comes with three holes whose debris can be easily removed by attaching a paper clip and having it work inside each one.

  • Mix of coffee ground and cocoa is one of the most difficult enemies in the exit needle, so note this when it comes to cleaning the needles
  • In term of tool to insert into the needles’ holes, it is recommended choosing a straightened paper clip or some tools like that. The tool should be able to get almost 1cm deep inside the holes

Rinse the water reservoir and removable lid. These arts cannot be washed with a dishwasher, do you will have to clean them by hand, using clean water and a non-rough cloth.

  • Do not use any cleansers and detergents. The chemicals used near the water reservoir are likely to pollute your water supply for future uses
  • Use a wet cloth to wipe out the parts thoroughly
  • Dry the parts thoroughly by letting them air dry or using a clean dish towel to

Clean the external part of the machine. Let’s make the front part of the brewer clean with a damp, non-abrasive cloth.

  • If you want, you can also take advantages of a soapy cloth for a more thorough cleaning. But ensure that no soap residue remained after you finish your process
  • Do not place the whole brewer in water

Reinstall the machine: It’s time to insert the parts into their right positions within the machine. Let’s insert the funnel back into the K-Cup and the K-Cup back into the brewer.

  • Pay attention to the arrows marked on the K-Cup and on the machine for exact installation
  • Reinstall the drip tray by sliding it back into its placement until it clicks

Method 2: Vinegar Soak

Operate the brewer with a vinegar rinse: Pour undiluted vinegar into the water reservoir, then run the vinegar through the brewer.

  • This is actually a descaling, so it should be performed 2 to 4 times a year. This process allows removing excess grime which sticks inside the brewer. The grime, if not removed, can weaken the machine’s ability to heat up and function
  • It is recommended to insert a ceramic mug on the drip tray to store the vinegar which brews through the machine
  • Never use any K-Cup during vinegar rinse process
  • If your machine is a mini model, pour 10 oz of unmixed white vinegar into the water reservoir. After 5 seconds, make the brewer handle lower and push the “Brew” button. The button should become red as the vinegar brewing is started
  • If your machine is a normal-size model, fill the water reservoir with 48 oz (1500 ml) of vinegar and push the “Brew” button. Let’s time for the participated parts to brew into the mug below
  • Reject the dispensed vinegar by putting it down the sink

Repeat the same vinegar rinse: this is the second vinegar rinse, but keep the vinegar inside some minutes so that it can descale the brewer more thoroughly.

Also, insert the ceramic mug on the drip tray to catch the released vinegar.

  • Do not take any K-Cup
  • Again, if you own a mini model, fill the water reservoir with 10 oz of white vinegar then lower the brewer handle 5 seconds. Push the “Brew” button, and decrease the machine’s power as it starts dispensing the vinegar. Let the remained vinegar in the brewer about 30 minutes before adjusting the power to standard level and finish the brewing cycle by pushing the “Brew” button
  • If your machine is a normal -size models, pour 48 oz of white vinegar into the water reservoir before pressing the “Brew” button. As there is the “Add Water” signal, temporary stop the process and let the vinegar sit in the brewer about 4 hours with the machine in “on” condition. Finish the process by dumping the rest vinegar

Finish the process with a fresh water rinse: operate the machine with a brewing cycle of fresh water to rinse away any remained vinegar residue.

  • Put a ceramic mug on the drip tray to store dispensed water
  • Pour fresh water into the water reservoir. If mini models, add 10; if standard-size models, add 48 oz (1500 ml).
  • Start the brewing by pressing the “Brew” button and have the machine run as usual. Reject the hot brewed water by pouring it down the sink
  • Run up to three rinse with cold water to eliminate any remaining vinegar taste
