If you have a Keurig water filter inside the reservoir, take that out too - the descaling solution should not be running through your filter.Make sure the brew head is also empty. No K-cup pod should be in the holder for the entire descale process."},{"number":2,"title":"Fill the Reservoir With Vinegar and Water","text":"Measure 14 ounces of distilled white vinegar and pour it into the reservoir. Then measure 14 ounces of fresh water and add that on top. The reservoir should sit roughly at the max line - half vinegar, half water.For larger Keurigs the ratio stays one to one - just scale up to fill the reservoir to its max line."},{"number":3,"title":"Enter Descale Mode","text":"Turn the machine off so no lights are on. Then press and hold the 8 ounce and 12 ounce buttons together for about three seconds. The K logo light and the descale light start flashing - that means you are in descale mode.Stay in descale mode for the entire process. Do not press power, do not exit. The machine handles each cycle differently when descale mode is active."},{"number":4,"title":"Run the Vinegar Through the Machine","text":"Place a large mug or measuring cup under the brew head and press the K button. The machine pushes about 14 ounces of vinegar mixture through and stops. Dump that liquid out, return the cup to the brew head, and press K again.Repeat until the add water light comes on - usually two cycles. The vinegar smells strong while it heats up, which is normal."},{"number":5,"title":"Refill With Fresh Water and Continue Cycles","text":"When the add water light comes on, take the reservoir off, rinse it well, and refill with plain fresh water to the max line. Snap it back on. Stay in descale mode the whole time - do not press power.Press K and run a fresh-water cycle into your catch container. Dump it. Press K again. Repeat about four or five times until the add water light comes on again and the descale light goes off automatically."},{"number":6,"title":"Run Two or Three Extra Rinses","text":"Once the descale light is off, the machine is technically done. But vinegar smell lingers, so it's worth running a few extra rinse cycles. Power the machine on, refill the reservoir with fresh water, and brew a few 12 ounce cycles into your catch cup.Lift the brew lever between cycles to reset the brew head if the K button does not respond. After two or three more rinses, your next coffee should taste like coffee, not vinaigrette."}],"recipe":null,"lastUpdated":"2026-05-20T13:28:56.259Z","published":"2026-05-01T17:06:29.339Z","license":"CC BY 4.0.
