Coffee Maker DIY Cleaner

Coffee Makers

I am extremely wary of coffee makers such as the Keurig maker because they can harbor mold, bacteria and algae like crazy. Think about it: the water reservoir is warm, wet and dark – ideal conditions for bacteria and mold to grow. Thankfully there is a solution for your personal coffee maker at home, and I’m going to show you what that is in a second. However, you need to be wary about coffee makers in public places like offices and hotel rooms, where you can’t necessarily be sure it has been cleaned properly. I never use them in hotel rooms. Instead I ask for a tea kettle, and if they can’t accommodate me (which is often the case!), I bring my own mini travel kettle. This way I can make my own tea. The same goes for water dispensers!! I rarely dispense water from one of those big coolers or machines unless I know for a fact that it is cleaned regularly (which they often aren’t).

So, here’s the eco-friendly solution because I really don’t want to have to use bleach.

For a regular sized coffee maker machine, you will need:

  • 1.5 cups white vinegar + 1 cup
  • 1/5 cups water
  • 1 NEW scrubber sponge
  • Earth-friendly dish soap


  1. Locate and remove the water reservoir from your machine*. Stand it in your sink.
  2. Place the vinegar and water in a measuring cup and microwave for 1.5 minutes.
  3. Be careful removing it because it will be super hot.
  4. Pour 3/4 of the water/vinegar into the reservoir. Leave for 3 minutes.
  5. Re-heat the water/vinegar for 50 seconds. Turn the reservoir upside down and pour the the vinegar/water over the base making sure you hit the opening. Leave for a minute.
  6. Fill your sink with hot, soapy water, and immerse the reservoir. Scrub it well. Rinse and air dry.
  7. Heat the remaining 1 cup of vinegar in microwave for 1.5 minutes. Pour it into a sprayer bottle. Spritz the rest of the machine, and leave for a few minutes. Dry with a clean cotton cloth.
  8. Reassemble your machine, and run a full cycle of fresh water through it before making your next cup of coffee.
  9. When you are not using your machine regularly. Remove the reservoir, wash and dry it before reassembling.
  10. Do the thorough vinegar clean at least once a month.

*If your reservoir doesn’t come out of your machine, you can pour the hot vinegar solution into it while it’s still in the machine.
