Descaling removes mineral buildup from your Keurig’s internal lines and heating element. Vinegar works but can leave a smell or taste if not rinsed thoroughly. You can descale your Keurig without vinegar by using Keurig’s official descaling solution, citric acid, or other descalers made for coffee makers. This guide covers the steps and options so your machine runs clean and your coffee tastes right. For general Keurig care and tips, see our best Keurig coffee maker and why your Keurig is brewing slowly (Priority 2).

Why Descale?

Hard water leaves mineral deposits (scale) inside the machine. Over time they can block flow, slow brewing, and affect temperature—so your Keurig may brew weak or take longer. Descaling dissolves that buildup. How often depends on your water hardness; every 3–6 months is typical. If you see a “Descale” message or notice slower, weaker brews, it’s time.

Keurig Descaling Solution

Keurig’s own descaling solution is designed for their machines and usually doesn’t leave a residual taste. Follow the instructions on the bottle: typically you add the solution to the water reservoir, run several brew cycles (without a pod) into a large mug or container, then refill with fresh water and run more cycles to rinse. Check your model’s manual for the exact sequence. This is the safest “no vinegar” option.

Citric Acid

Citric acid (powder or liquid) is a common vinegar alternative. You mix it with water according to the product instructions (often 1–2 tablespoons per reservoir of water), then run the same type of descaling and rinse cycles as with vinegar or Keurig solution. Rinse thoroughly with plain water afterward. Citric acid is odorless and won’t leave a vinegar smell.

Other Descalers

Other coffee maker descalers (often based on citric or other food-safe acids) are available at hardware or grocery stores. Use only products intended for coffee machines and follow the label. Avoid harsh chemicals not meant for food-contact surfaces.

After Descaling

Run multiple rinse cycles with plain water until no descaling solution or taste remains. Wipe the drip tray and exterior. Your Keurig should brew faster and more consistently.

You can descale your Keurig without vinegar by using Keurig descaling solution, citric acid, or another coffee-maker descaler. Follow the instructions, then rinse well with water. For Keurig tips and machine picks, see our best Keurig coffee maker guide.
