Step-by-Step Guide to Descaling a Keurig K-Supreme and K-Supreme Plus with Vinegar:
The process will take approximately 30 minutes to an hour.
Step 1: Preparation
Ensure that your Keurig machine is turned off and unplugged. Make sure there is no K-Cup in the machine.
Remove the water reservoir, dump out any water, and remove any water filter if present.
Step 2: Vinegar + Water Fill
Fill the reservoir with 14 ounces (approximately 2 cups) of distilled white vinegar.
To the vinegar, add an equal amount of fresh water (14 ounces or 2 cups). This creates a 1:1 ratio of vinegar and water in the reservoir.
Step 3: Enter Descaling Mode
Plug in and turn off the machine. Hold the 8-ounce and 12-ounce buttons together for three to five seconds. The descale light should come on, indicating that the machine is in descaling mode.
Step 4: Run Descaling Cycles
Press the flashing “K” button to start the descaling process. The machine will run approximately 12 ounces of vinegar solution through the machine into your container. Once finished, discard the hot solution in the container.
Press the “K” button again and repeat the process until the “add water” light comes on.
Step 5: Rinse and Refill Reservoir
Remove the water reservoir, discard any remaining solution, and rinse thoroughly with soap and water. Refill it with fresh water to the max line and reinstall the reservoir.
Step 6: Run Fresh Water Cycles
With the machine still in descaling mode, press the flashing “K” button to start running fresh water through the machine. Discard the water in your container after each cycle.
Press the “K” button again, repeat the process, and keep an eye on the “descale” light.
Step 7: Check the Descaling Light
If the descale light is still on, you might need to repeat the descaling process or consider using a Keurig descaling solution.

Keurig Mastery: Tips for Top-Notch Brews
- Regular Maintenance: Descaling should be done every three to six months, depending on the hardness of your water. Don’t wait for the descale light to come on, as this might mean there’s already significant build-up affecting the performance of your machine.
- Extra Rinsing: When using vinegar, it’s advisable to do extra rinsing to flush out all the vinegar.
- Refill the reservoir to the max line with fresh water to achieve that. Turn on the machine and run additional new water cycles (approximately 2-4 times) by pressing the 12-ounce and the “K” buttons.
- External Cleaning: Don’t forget to also clean the machine’s exterior with a soft cloth or sponge and mild dish soap.
Following this guide, you should be able to successfully descale your Keurig K-Slim with vinegar, improving your coffee maker’s performance and lifespan.

Can I use something other than white vinegar to descale my Keurig?
Yes, you can also use Keurig’s own descaling solution or other descaling products designed for coffee machines. However, white vinegar is a cost-effective and readily available alternative that works effectively.
Will the vinegar leave a taste in my coffee?
Not if you thoroughly rinse your machine afterward. It’s important to run several cycles of fresh water through the machine after descaling to ensure all vinegar residue is gone.
Can I use apple cider vinegar instead of white vinegar?
It’s recommended to use white vinegar for descaling as it’s odorless and colorless. Apple cider vinegar may leave a slight taste or color and may not be as effective in removing mineral deposits.
