1
Remove the reservoir filter and K-cup from your Keurig. If you have a filter inside your Keurig’s reservoir, empty the water and pull out the tall plastic piece off of the bottom to remove it. Then, open the machine and take out any K-cups or reusable filters inside.^{[1]

- If your brewer has an Auto-Off feature, turn it off as well so the machine doesn’t shut down while you’re cleaning it.
2
Fill the reservoir with a 50-50 mix of white vinegar and water. Cleaning expert James Sears recommends that you “pour white vinegar into [the] reservoir halfway” and fill up the rest with clean water.^{[2]

Run the vinegar solution through your Keurig. Put your largest mug underneath the Keurig’s spout to catch all of the vinegar solution that drains out. Either run your Keurig’s Descale setting or press the “Brew” button so the solution goes through the machine.
- Some models, such as the Keurig Slim, require you to press and hold certain buttons or find the Descale option in a menu. If you’re not sure if your coffeemaker has a descale setting, check the official support page for your specific Keurig model.
- If you’re manually pressing the Brew button, use the largest mug setting. Once it finishes, empty the mug and run additional brew cycles until the reservoir empties.
- Descaling a Keurig typically takes between 20–45 minutes, but it may vary on the model you have.
- Cleaning expert James Sears explains, “White vinegar…is slightly acidic so it will work to break down the scale, which is mostly mineral deposits such as calcium in your water that have settled over time.”^{[4]

Our Expert Agrees: Descale your Keurig at least every 6 months. You'll need to descale every 3-6 months or whenever you notice scale build-up, which looks like white calcified spots. The harder your water is, the more often you'll need to descale, unless you use distilled or bottled water in your coffee water reservoir.

Cleaning the Exterior and Removable Parts

While it depends on the Keurig model, you normally can remove the reservoir tank, lid, drip tray and cover, K-cup holder, and funnel. Carefully pull the pieces apart until they come free and set them aside.^{[9]

Wash the removable parts with soapy water. Place the components into a sink filled with warm water and a few drops of dish soap. Scrub the parts with a soft, clean sponge or microfiber cloth before letting them air-dry.^{[10]

- Keurig pieces are usually dishwasher-safe, but check the user manual before washing them this way.
- While it’s easier to wash the pieces with soapy water, you may also wipe them clean with a 50-50 solution of white vinegar and warm water.
- Avoid drying pieces off with a cloth because it could leave behind lint.

Use a paperclip to clean the Keurig’s needle. Look for the needle inside the machine where you place the K-cups. Cleaning expert Ryan Santos says, “Use a paperclip or a toothpick to gently clear any clogs or debris from the needle.”^{[11]

Vinegar works great for cleaning your Keurig. Just put a 50/50 mixture of white vinegar and water in the reservoir and run a few cycles to clear it out.

Question

After descaling my Keurig machine my coffee I just brewed is thick and cloggy. Any advice?

Community Answer

Did you go through the rinsing process at least 12 times (12 large cups worth of clean water after the solution)? You may have to fill the water reservoir a couple of times. This should wash away the scales that you descaled (calcium deposits) as well as residual solution. You want to make sure to not use any pods during the rinsing process, just water. The clumps are probably the calcium and/or the descaling solution. You can also use white vinegar to clean/descale. Again, you will need to thoroughly rinse by running about 12 large cups of water through so that it doesn't taste like vinegar or get clumps. This way is cheaper too!

Replace water left in the Keurig reservoir after 1 week so it doesn’t taste stale or leave mineral deposits.
