All coffee machines are a little different, but you can clean them using this simple method. It’s important to not only wipe coffee machines clean and wash the pot after every brew but to also deep clean it at least once per month to make sure there’s no mould growing somewhere inside the pot. Unfortunately, because coffee machines hold a lot of moisture, they’re at a high risk of harbouring mould, but a deep cleaning is sure to take care of that for you.

 

  1. 1. Remove removable parts. The first thing you want to do is take off every part of your machine that you can easily remove, including the coffee pot, filter holder, and possibly the lid if it snaps off easily.
  2.  
  3. 2. Wash removable parts. Although some coffee machines will have removable parts that you can wash in the dishwasher, others recommend hand-washing these parts, so if you don’t know, it’s better to wash them by hand just to be safe. Just use regular dish soap with warm water.

  5. 3. Wipe down the outside. Next, you’ll want to wipe down the outside of the coffee maker with a rag filled with soapy water to get off any dust or grime that may be on the outside. Clean especially well where the pot sets to make sure to get up any coffee drips.

  7. 4. Replace removable parts. Once all the parts are clean and dry, you can put them back on the machine as they were and begin preparing to clean the inside parts that you can’t reach with a rag.
  8.  
  9. 5. Make a cleaning mixture. To make a cleaning mixture that will go through your machine to clean out the insides, mix equal parts of white distilled vinegar and water. The exact amount will depend on the size of your coffee machine, but you will want to make sure you have enough to fill the reservoir at least halfway. So, if you have a 4-cup machine, you need to make 2 cups of this solution.
  10.  
  11. 6. Pour in the cleaning mixture. Carefully pour in the mixture of vinegar and water into your coffee machine’s reservoir.
  12.  
  13. 7. Start brewing. For the first part of the internal cleaning portion, you’ll need to allow this solution to brew until about half of it has passed through the machine. You can either check to see how much is left by looking at the reservoir or the coffee pot. Once it reaches the halfway point, shut the machine off.
  14.  
  15. 8. Let it sit. Set a timer for one hour and allow the solution to sit for that time. This will give the bacteria-and-mould-fighting vinegar time to work on all the internal pieces that you can’t otherwise clean.
  16.  
  17. 9. Finish brewing. Once the hour is up, you can turn the machine back on and allow it to finish brewing the solution. You can then dump out what’s in the coffee pot. 
  18.  
  19. 10. Rinse. In order to rinse out the internal pieces to avoid some very sour coffee in the morning, fill the reservoir at least halfway with fresh water and allow it to run a brewing cycle with just water, be sure to dump that water as well
  20.  
  21. 11. Repeat. To make sure that all the vinegar is out of the machine, you’ll need to do one more rinse brew with another pot of freshwater 
  22.  
  23. 12. Wipe everything down again. By now, you will probably have gotten some small amount of moisture on the outside of the machine, so to finish up, you can quickly wipe down the outside of the machine one last time with a dry rag or paper towel. Now you have a clean coffee machine that is free from mould and other harmful bacteria that may have been lurking inside.
