How to Clean 7 Brand Name Coffee Makers

Tip: Always make sure the empty carafe is in your machine to catch the dirty water while cleaning your machine.

1. How to clean Cuisinart coffee maker

Cleaning a Cuisinart coffee maker is a simple process. Make sure you follow the cleaning process at least once a month if not more so that you don’t get bacteria growth or mold.

Supplies:

  • water
  • vinegar
  • nonabrasive scrubby pad/brush
  • mild dish soap

Steps to clean a Cuisinart coffee maker:

  1. Rinse: Run a complete cycle without coffee grounds using a paper filter to help remove scale and gently lift grime. Discard the water.
  2. Sanitize: Use a mix of 1/3 white vinegar and 2/3 water and run a cycle to sanitize the unit and kill any lingering bacteria or mold. If your machine has a “clean” button you can press it (while the machine is plugged in but turned off) and then when it glows turn the machine on and it will be in clean mode. When you hear five beeps the cleaning mode will be finished. Otherwise, proceed with the next steps
  3. Rinse again: Run another cycle or two of plain water to remove any vinegar and finalize the cleaning process.
  4. Scrub the carafe to remove grime and allow everything to dry completely before your next use.
  5. Soak as required: If you have trouble removing the coffee film from the carafe try letting it soak in hot soapy water for a few hours (or overnight) and then gently scrub with warm soapy water and a little vinegar.
