Key Takeaways:

This is how you can clean your coffee maker.

Step 1: Empty the carafe and grounds.

Step 2: Mix one part water to one part vinegar to make a cleaning solution.

Step 3: Pour the solution into the water chamber and run a half brew cycle.

Step 4: Throw out the vinegar-water solution and run a fresh water cycle.

Step 5: Wipe down your coffee maker.

Is your coffee tasting bitter lately? Your coffee maker might not be as clean as you think. 

Some of the warning signs of a dirty coffee maker are clear: Oily sludge and mineral buildup eventually form on your coffee maker and pot, creating stains, gumming up the brewing process, and producing bitter-tasting brew.

To make sure you don’t drink up any of the germs or coliform bacteria this appliance has been known to grow, it’s essential to keep your machine clean and your coffee tasting great. 

Wash removable parts with dish soap after every use

This is important because it helps remove coffee, grinds, and oil that are left behind. You can hand wash at the sink with warm and soapy water, but usually the pieces are dishwasher-safe. And don’t forget to wipe down the outside and the warming plate where spills can burn on.

How to Deep Clean a Coffee Maker

What You’ll Need

  • Water
  • White vinegar
  • Hot soapy water
  • Sponge
  • Damp dish towel
  • Dry dish towel


Empty the carafe and grounds: Empty and rinse the carafe and dump out any coffee grounds left in the filter.

Make your cleaning solution: Mix one part water to one part vinegar.

Pour the solution into the water chamber: Fill the water chamber to its full capacity with equal parts white vinegar and water. I used the carafe to measure equal parts of each.

Run a half brew cycle: Start a brew cycle. Midway through the brew cycle, turn off the coffee maker and let it sit for an hour.

Finish the brew cycle: After an hour, turn on the coffee maker and let the brew cycle finish.

Discard the vinegar-water solution and run a fresh water cycle: After the brew cycle has completed, pour out the vinegar-water solution and fill the water chamber with fresh water (no vinegar). Run a whole new brew cycle just with the water. Repeat two more times, allowing your coffee maker to cool slightly between brews.

Wipe down your coffee maker: Wipe down the exterior of your coffee maker, and wash the carafe and filter basket in hot, soapy water. Reassemble and make delicious coffee!

Use a Descaling Solution

If the mineral buildup in your coffee maker is particularly heavy or the taste doesn’t improve, repeat the process with a manufacturer-approved descaling solution.
