How to Clean a Coffee Maker With Vinegar
Mineral scale builds up inside every drip coffee maker, slowing the brew, making it sputter, and giving coffee an off taste. A simple vinegar descale every month or two fixes all of it. Here is the quick routine.
Mix the Solution
Fill the reservoir with a 50/50 mix of white vinegar and water. For a heavily scaled machine, you can go up to 2 parts vinegar to 1 part water.
Run a Half Cycle and Soak
Start a brew cycle (with a clean filter in place, no coffee) and let about half run through, then turn it off and let it sit for 30-60 minutes. This lets the vinegar dissolve the scale inside the tank and tubing.
Finish and Rinse
Turn it back on to finish the cycle, then run two or three full reservoirs of fresh water through to flush out all the vinegar — otherwise your next pot tastes like salad dressing.
Wash the Removable Parts
Wash the carafe, filter basket, and lid with warm soapy water. Wipe the warming plate once cool. Doing this every month or two keeps the machine fast and the coffee tasting clean.
