Anyone know how to clean a Keurig?

Disassemble the brewer. Open the cover of the brewer by lifting the handle and remove the K-Cup holder inside.

• To remove the K-Cup holder, grab the top of the holder with one hand. Using your other hand, push up on the bottom of the K-cup assembly from below. The assembly should eventually release.
• Use caution when removing the K-Cup holder. There are two sharp needles inside that could hurt you if you remove the assembly haphazardly.

The remaining pieces should disassemble with relative ease. Gently pull on the funnel until it separates from the K-Cup holder. Remove the drip tray by simply pulling it away from the base of the machine.

or

Run a vinegar rinse through the machine. Fill the water reservoir with undiluted vinegar. Brew the vinegar through the machine.

• This process is also known as descaling and should be done every 3 to 6 months. Descaling the brewer removes excess grime sticking to the inside of the brewer. If left alone, this grime came have a serious negative impact on the brewer's ability to heat up and function properly.
• Place a ceramic mug on the drip tray to catch the vinegar that brews through the machine.
• Do not use a K-Cup while performing the vinegar rinse.
• If using a mini model, fill the water reservoir with 10 oz (300 ml) of undiluted white vinegar. Lower the brewer handle after 5 seconds and press the blue "Brew" button. It should turn red and begin brewing the vinegar through the machine.
• If using a standard-size model, pour 48 oz (1500 ml) into the water reservoir and press the "Brew" button. Allow the contents to brew into the mug below.

Discard the warm, dispensed vinegar by dumping it down the sink.

Here's what I found: If you use citric acid you will need an acid-to-water ratio of about one part acid to 20 parts water. For vinegar and/or lemon juice, the mixture is a 50/50 ratio. Pour either solution into the water reservoir of your machine. Choose the largest volume brew cycle and press start. If your machine will not brew without a pod in place, simply use an old, used pod. IMPORTANT: If you used citric acid or lemon juice you will need to run 2 water-only cycles to rinse the machine out. If you used vinegar, 4-5 water-only cycles will be necessary to thoroughly remove the smell and taste.

Good luck!!

the vinegar and water will descale. be sure to keep running water through or you will taste the vinegar. also, if it is clogged or liquid is not coming out of the needle (that punctures the kcup)-take a paper clip end and put into the 3 holes of the needle to make sure they are free of grounds.

Thank you!

I use white vinegar to descale coffeemakers as well, but never run it through just once. I catch it and run it through several times before discarding and doing several rinses with plain water.

Thank you!
