How to Clean a Coffee Maker with Vinegar

Introduction

Over time, mineral deposits, old coffee oils, and residue can build up inside your coffee maker, affecting taste and slowing down brewing. Cleaning your machine with white vinegar is one of the easiest and most effective ways to restore performance and keep your coffee tasting fresh. This method works for most standard drip coffee makers.

What You'll Need

• White vinegar

• Fresh water

• Dish soap

• Soft sponge or cloth

• Optional: coffee filter

Steps

Empty the coffee maker and remove any used filter or coffee grounds.
Fill the water reservoir with equal parts white vinegar and water.
Place an empty coffee filter in the basket to catch debris.
Start a brew cycle and let it run halfway. Then turn off the machine and let it sit for 30 minutes.
After soaking, turn the coffee maker back on and complete the brew cycle.
Empty the pot, discard the filter, and rinse both thoroughly.
Fill the reservoir with clean water and run a full brew cycle to flush out any remaining vinegar.
For best results, repeat the water-only rinse cycle once more.
Wipe down the exterior, warming plate, and removable parts with warm soapy water and dry completely.

Alternative Methods

• Use a commercial coffee maker descaling solution instead of vinegar for machines that specify it.

• Clean removable parts by soaking them in warm, soapy water to remove stains and oils.

• For stubborn buildup, run an additional half-vinegar cycle followed by two rinse cycles.

What NOT to Do

• Do not use bleach—it can damage the machine and is unsafe to ingest.

• Do not skip the rinse cycles, as vinegar can leave a strong flavor behind.

• Avoid scrubbing heating elements or internal parts that are not designed to be removed.

• Do not submerge the entire machine in water.
