How to descale a Keurig coffee machine

Reading Time: 2 minutes

If your Keurig is brewing slower than usual or your coffee tastes off, it’s time for a deep clean. Over time, mineral buildup (limescale) from water can clog your machine, affecting performance and taste. Descaling removes these deposits and ensures your coffee maker runs efficiently. Follow this step-by-step guide to keep your Keurig in top shape.

Why Descaling Your Keurig is Important

  • Improves Coffee Flavor: Mineral buildup can affect the taste of your coffee.
  • Prevents Clogs and Malfunctions: Scaling can block water flow and damage the machine.
  • Extends the Machine’s Lifespan: Regular maintenance keeps your Keurig working longer.
  • Ensures Proper Brewing Temperature: Buildup can affect heat consistency, leading to under-extracted coffee.

How Often Should You Descale a Keurig?

  • Every 3–6 months: Recommended for regular users.
  • Monthly: If you use hard water or notice a decline in performance.
  • Immediately: If your Keurig displays a descaling alert or water flow is restricted.

What You Need to Descale a Keurig

  • Keurig Descaling Solution (or white vinegar as an alternative)
  • Fresh water
  • Large mug
  • Soft cloth or sponge
  • Paper clip or needle (for cleaning the needle, if needed)

Step-by-Step Guide to Descaling Your Keurig

Step 1: Prepare Your Keurig

  1. Turn off and unplug the machine.
  2. Remove the water reservoir, drip tray, and K-cup holder.
  3. Empty any remaining water from the reservoir.

Step 2: Add Descaling Solution

  1. Fill the water reservoir with Keurig Descaling Solution and an equal amount of water.
  2. Place a large mug on the drip tray to catch the liquid.

Step 3: Run the Cleaning Cycle

  1. Turn the machine back on and start a brew cycle without a K-cup.
  2. Discard the hot liquid and repeat until the reservoir is empty.
  3. Let the machine sit for 30 minutes to break down mineral deposits.

Step 4: Rinse the Machine

  1. Refill the reservoir with clean water.
  2. Run multiple brew cycles with just water to remove any leftover solution.
  3. Repeat until there’s no vinegar or solution taste in the coffee.

Step 5: Clean the Needle (Optional)

  1. If your Keurig is still brewing slowly, use a paper clip or needle to unclog the needle.
  2. Insert the tool into the needle to remove coffee grounds or buildup.
  3. Run another water-only cycle to clear debris.

Alternative: Descaling Keurig with White Vinegar

If you don’t have Keurig’s official descaling solution, use white vinegar:

  • Mix equal parts white vinegar and water in the reservoir.
  • Follow the same cleaning steps.
  • Run extra water-only cycles to remove vinegar taste.

How to Keep Your Keurig Clean

  • Use Filtered Water: Reduces mineral buildup.
  • Clean Removable Parts Weekly: Wash the reservoir and drip tray with warm soapy water.
  • Wipe Down the Exterior: Use a damp cloth to keep your machine looking new.
  • Replace Water Filters: If your Keurig has a filter, replace it every 2 months.

By following these steps, you’ll keep your Keurig coffee machine running smoothly, ensuring every cup tastes fresh and delicious. ☕
