How Do You Deep Clean a Coffee Maker?

If your coffee isn’t tasting too good lately, there’s a good chance your coffee maker needs a bit of cleaning. Plus, according to a study, most of these household machines contain mold and yeast. That means they’re even dirtier than the average restroom faucet handle.

To ensure that your body doesn’t take in the coliform bacteria or germs housed in this brewing machine, make sure to give it a regular cleaning after every use and deep cleaning once a month.

Coffee Maker Cleaning Methods

To say that we use our coffee makers frequently is an understatement. This appliance is what we rely on every day. Often more than once, to create the perfect cup of coffee that gets us going. Yet as much as it has gotten to the point of not being able to live without this machine, most of us haven’t been taking care of it as well as we should.

Using the coffee maker correctly is one thing many coffee lovers have gotten the hang of, but cleaning it properly is another story. Some will be fine with just wiping it down or putting off washing its parts until the next day. Then, some clean their coffee makers after every use but neglect the deep cleaning procedure that is necessary every month.

Overlooking even one of these procedures or not doing them correctly can lead to some bitter-tasting coffee that ruins your day more than it perks it. Let’s take a closer look at these must-know methods for addressing your brewing machine’s cleaning needs.

Regular Cleaning

Ideally, your coffee maker should be cleaned after every use to get rid of the grinds and oil left behind. Here’s a recommended process of doing so:

  1. Wash the Parts: Handwash the machine’s dishwasher-safe parts using warm and soapy water.
  2. Wipe Dry: Wipe down the outside of the outside pieces, particularly the warming plate, where spills tend to get stuck.
  3. Leave Them Out to Dry: To really keep those germs at bay, make sure to leave the lid of the reservoir open when drying. In this way, it will dry completely and leave no moisture for germs to grow.

Deep Cleaning 

This process involves eliminating the hard-water minerals that build-up in your brewing machine’s inner workings. These calcified mineral deposits reduce your machine’s drip rate and even ruin it completely in the long run. To get your appliance back to peak shape, you’ll need to cleanse and decalcify it monthly using every coffee enthusiast’s favorite cleaning substances: vinegar and baking soda.

Here’s how you deep clean your coffee maker correctly:

  1. Brew the Vinegar and Water Solution: Fill the machine’s reservoir with one part vinegar and one part water. Then, put a paper filter into its empty basket. Put the pot in position, then brew the mixture halfway. Power off the appliance and let the solution sit for half an hour.

Turn your machine back on and boil the mixture the rest of the way. Then, dump the mixture. Lastly, place a new paper filter and brew clean water to rinse away any remaining solution.

    1. Remove Stains: Use a sponge and some baking soda to deal with those hard-to-remove stains. If the stains still won’t budge, create a mixture of two parts baking soda and four parts water and let it sit in the reservoir overnight.


  • Wash Your Coffee Maker’s Parts: Although this is something you do after every use, make sure not to overlook it during a deep cleaning procedure. You still need to wash the coffee pot, brew basket, and reusable filter (if your machine has one) with warm soapy water after completing the first two parts of the deep cleaning process.


Deep Cleaning an Old Carafe

If your coffee maker’s been around for quite some time, then even regular cleaning won’t be enough to get rid of the carafe’s dingy appearance. To ensure that your carafe remains shiny, follow these two easy steps:

  1. Use Water and Rice: Fill the carafe with warm, sudsy water and a bit of rice. Then, stir the mixture to loosen any hardened sludge. 
  2. Use a Sponge to Clean off the Gunk: Using a scrub sponge, remove the tiny particles of dirt stuck to your carafe. Rinse properly.

Deep Cleaning Your Coffee Maker

When it comes to coffee maker cleaning methods, it’s important to keep in mind that some brands may have their specific cleaning instructions. See this comparison review of the Keurig and Mr. Coffee brands to get a clearer picture of how they may not necessarily require the same cleaning and shining procedures.

That said, generally, a deep cleaning procedure for a coffee maker shouldn’t be too hard. As soon as you establish that your appliance’s parts are washable, gather your sponge, vinegar, and baking soda and start performing the process as indicated above. Do this regularly once a month, while also washing your machine after every use, to keep it looking great and producing that perfect, flavorful cup every time.
