How To Clean Coffee Maker - Simple and Effective Ways

Many people have taken to drinking coffee. Most of us like to wake up to a cup of coffee or two. But when was the last time you cleaned your coffee maker thoroughly? Well, take a break from your brewing. Peep inside the internal components of your best coffee maker. Is it unsightly?

Are you worried about the unusual taste in your coffee? Most probably you have skipped cleaning your coffee maker several times. Built-up minerals, mold, and yeast growth have taken over. Hence the strange taste. With just white vinegar, baking soda, bleach, or lemon juice you can solve this problem. Is this the case with your coffee maker? If yes, it's because you have taken months or even longer to clean the internal parts of the coffee maker. A coffee pot left idle on the counter over a weekend is likely to have mold and yeast growing in it.

So instead of taking in caffeine, you have probably been drinking contaminated coffee every morning. The unpleasing sight in your coffee maker may even endanger your life, and here is why:

5 Reasons Why You Need to Clean Your Coffee Maker

A recent study conducted in 22 households by NSF revealed that about 50 percent of coffee makers had yeast and mold growth in their reservoir. You may not believe it. Did you know that your dirty coffee maker could be harboring more germs than even the toilet seat or bathroom door? The same study suggests that cleaning coffee maker machines regularly bestows the following benefits to you:

1. Improved coffee taste

We all know the taste of real coffee. Failure to clean the internal components of the coffee maker may change your coffee flavor and make it unpleasantly bitter. That happens due to the buildup of coffee oil in the pot. If it is safe to do so, clean the coffee maker in the dishwasher using hot soapy water and rinse thoroughly. The oddly bitter taste will then disappear.

2. Eliminate the germs residing in the moist and warm environment

Normally germs love to breed in a warm moist environment. A dirty coffee maker presents an ideal breeding ground for germs. After each brewing, remove the lid; drain the liquid that might have remained in the container. Leave the lid open and give the coffee maker time to dry out. Doing so keeps the container dry, thereby eliminating the chances of germs growing in it. 

3. Maintain a healthy life

As pointed out before, coffee makers can be the breeding grounds of yeast and mold. The two substances can negatively impact lives, especially if you are asthmatic or allergic. For example, research conducted out by the NCBI shows that molds and yeast can trigger an allergic reaction or asthma.  Cleaning out the two substances, therefore, reduces the chances of asthmatic attack or allergic reactions.

4. Shorter brewing time

When preparing coffee using hard water regularly, calcium deposits bit by bit in the brewing pot. In the end, it provides a kind of insulation. Consequently, the buildup calcium deposits increase the brewing time. A thorough monthly cleaning (as we’ll be discussing later in the article) removes the insulation thus reducing the brewing time.

In addition to the dangers described above, the higher accumulation of mold and yeast in the coffee maker endangers even your infant’s life.  For example, according to the National Center for Biotechnology Information, there is a link between kidney disease and exposure to mold (mycotoxins).  Therefore, it is important to learn how to clean a coffee maker.

This is because the vinegar and water mixture has been dripping from the coffee maker into the pot. Leave the mixture in the pot to cool off. The vinegar will help to descale the coffee maker. 

Do likewise with the rinsing water during the rinse cycle in the above brewing cycle. Once the water has completely cooled, then empty the container and wash in the ordinary way.

Method 3: using baking soda

Even if you can’t get lemon juice, you can still clean your coffee machine with baking soda. This substance is a natural cleaning detergent which is also non-hazardous.

You can also clean your automatic coffee maker with bleach. However, it is important to point out that it is highly corrosive. Consequently, you should neither add bleach directly into a coffee maker nor use it in excess. Otherwise, it will surely corrode and damage the coffee machine. Just a few drops of bleach into the cleaning water are enough to remove the build-up stains and gunk.

What you need

  • Filter paper
  • 2 tablespoons of bleach
  • Cleaning water
  • Mixing jug
  • Stirring rod

5. Plug in the machine and run the brew cycle for a few minutes

6. Switch off the coffee maker. 

7. Discard the dirty water.

8. Add plain clean water to the reservoir and run the brew cycle several times to rinse the bleach traces out of the machine's system. 

9. Discard the rinsing water out of the coffee pot and let it dry.

Method 5: using ice and salt

So far, we have described how to clean the coffee maker machine using various methods. What if you have a narrow-mouthed coffee pot which has not been washed for weeks? For instance, consider the coffee carafe shown below:

The coffee carafe

Cleaning stubborn stains from such a narrow-mouthed coffee carafe could be challenging; that’s why we recommend the combination of ice and salt. Here is how to clean coffee pots with a narrow mouth.

What you need

  • 1 cup of cold water
  • 1 ½ cups of crushed ice
  • 4 tablespoons of salt
  • A lemon portioned into quarters

Steps

1. First, let the coffee pot cool down especially if it is a glass carafe. Sudden cooling of hot glass by adding cold water may shatter it.

2. Squeeze out the juice from the lemon quarters into the coffee pot. Drop the squeezed-out rinds into the pot as well. 

3. Pour the crushed ice, salt and water into the pot

4. Hold the pot securely by the handle and swirl in a clockwise direction for about 15 seconds.

5. Next swirl the mixture in an anticlockwise direction.

6. Repeat several times until the stains are removed. If there are still stubborn stains at the bottom, let the mixture stand overnight.

7. Finally, dump the whole mixture. Rinse the pot thoroughly with COLD water

Using the above method, you shouldn’t experience difficulty in cleaning even the most stubborn grease and built-up mineral salts from your coffee carafe.  

Author’s recommendation

You don’t have to wait until mineral deposits accumulate in the coffee maker. Clean your coffee machine on a regular basis. For example, use lukewarm soapy water and a sponge to clean your coffee pot daily. If a sponge can’t fit in the carafe then add a little rice into the container and swirl.

On a monthly basis, descale the coffee maker using any of the above methods. Alternatively, do the cleaning as often as necessary; some coffee makers will even give you a warning indicating when there is excess mineral accumulation.  

Conclusion

Failing to clean your coffee maker is a risk to your health. Moreover, you have no reason for failing to do so. The above detergents can easily be obtained at home. From vinegar, lemon juice, baking soda or bleach, you get all of them from your kitchen cupboard. Happy cleaning!
