Table of Contents

Some people are grossed out by the idea of drinking coffee from a pot. After all, it’s just hot water that has been boiled inside a metal container. But others love their cafetiere so much that they don’t mind about the fact that it can be contaminated with bacteria if not cleaned thoroughly after every use.
If you are one of these people who love your cafetiere, then you’re probably wondering whether or not you should be concerned about germs growing in your coffee maker. The answer is yes, you should be worried about this. Because even though most machines come with a descaling solution to help wash out any dirt and residue left behind by old coffee grounds, there’s still a chance that they could harbor some bacteria if they aren’t cleaned properly after every use.
Fortunately, cleaning your coffee maker isn’t too difficult and doesn’t take long at all either. If you read through the following article, which explains how to clean your coffee maker thoroughly so it doesn’t become breeding ground for bacteria again as soon as you switch it on next time, then you will feel much better knowing that no matter how often you brew coffee from it, not even one germ will make its home in there again!

What Is The Best Way to Clean a Coffee Maker?

The first thing to do when you have a coffee maker is to check the water level, and then make sure that it’s as hot as possible. The next step is to take out any old coffee grounds and put in fresh ones. Then wash the carafe with hot soapy water to ensure that it stays clean and hygienic.
A lot of people are still concerned about the process of cleaning a coffee maker; however, once you know what you need to do, then doing it won’t be too hard at all. Eventually, this will become a habit for you, and you won’t have a problem figuring out how to clean your coffee maker for next time!
In summary:
Coffee makers can act as breeding grounds for germs if not cleaned properly after every use. However, there are many ways that people can go about cleaning their machine so they’re bacteria free!

Equipment You’ll Need

You’ll need a scrubby, a jug of water and a reusable coffee filter.
The first thing you’ll need to do is remove the device from the machine. This can be done by pressing down on the button that is located on the side of the device, or it can be done by lifting the handle up (this will release it from its spot). Next, unscrew all of the parts so you are able to spray them thoroughly with your descaling solution. If this doesn’t come with your machine, then you should buy some vinegar and set out to clean your machine properly with it. After spraying all of these parts in question, you will put them back together again and throw away your vinegar.
Now that all of those steps have been taken care of, dip your scrubby into some water (you should use around 2 cups of water) and then carefully scrub away at all areas in which bacteria might grow at this point is when you should also use your reusable coffee filter if needed to ensure that every nook and cranny has been removed from possible bacterial growth. After cleaning this part really well, now it’s time to do something about any sticky residue that might have accumulated throughout your device. You may need to give it a quick rinse under some hot running water before throwing away any leftover sticky stuff but make sure not to over-saturate yourself as this could damage your machine.

Remove The Plunger From the Cafetiere

One of the most important things to do when you want to thoroughly clean your coffee maker is to remove the plunger from the cafetiere. This will stop any water that has been left in the bottom of your device from stagnating and turning into a breeding ground for bacteria. Alternatively, you could use a paper towel or a cloth to soak up any residual water in your coffee maker before you switch it on again for a fresh brew.

Use a Sharp Knife to Cut Through the Build-Up

on the Bottom
You can use a small knife to cut through any build-up on the bottom of your coffee maker. After you have done this, you will see that the whole bottom is now smooth and clean.
There are three important steps that you should take if you want to make sure your coffee maker is bacteria free:
First, use a sharp knife to cut through any build-up on the bottom of your coffee maker. If there’s a lot of buildup, then it would be best if you used a scalpel or an X-rated lancet in order to get rid of it completely.
Secondly, scrub the inside walls with a solution made using bleach and water. Use one teaspoon of bleach for every two cups of water and place the mixture into an old plastic bottle before opening it up.
Thirdly, fill up your machine with hot water and run it through again. This will help remove any residue that was left behind by the bleach solution, which may have dissolved some of your coffee beans while doing so.

Keep Scrubbing Until No Dirt Shows Up on Your Scrubbing Brushes

The most important part of cleaning your coffee maker is to make sure you scrub it until all the dirt and residue is gone. So, after you’ve rinsed out the water and taken your pot to a sink to drain off any leftover water, you should take some time to get down on your hands and knees and scrub the exterior of your machine. When you’re done scrubbing, wait for a few minutes before turning it back on again.
Once it has been running with fresh water for a few minutes, turn on the steam mechanism again until no more scum or dirt show up in the basket. Now that all the dirty stuff is gone, it’s time to clean out the filter basket too!

Don’t Forget the Drip Tray and Thermometer

Some people might say that coffee makers are self-cleaning and don’t need to be cleaned as often. However, this is not true. The drip tray and the thermometer are both important parts of your coffee maker that should be cleaned every time you use them. When these parts are dirty, it can result in a brew that is too hot or too cold. What happens when you put something with a lot of bacteria in the drip tray? If the coffee isn’t filtered or if the water drops on old grounds, then those germs could contaminate your coffee and make you sick.

Cleaning your coffee maker will also help to prolong its lifespan. This means you’ll be able to save some money by making fewer purchases of replacement parts over time. Plus, if you keep your machine clean and healthy, then it will last longer than if it was left unclean and unhealthy.


You should be concerned about germs in your coffee maker because even though most machines come with a descaling solution, there’s still a chance that they could harbor some bacteria. And the best way to avoid this is to clean your coffee maker thoroughly so that it doesn’t become a breeding ground for bacteria again as soon as you switch it on next time.


What is the purpose of descaling a coffee maker?

The purpose of descaling a coffee maker is to remove residues left from coffee brewing. Coffee brewing creates acidic by-products that can etch the inside of your coffee maker. These residues eventually build up and create a breeding ground for bacteria and fungus. The purpose of descaling your coffee maker is to remove these residues and restore your coffee maker to its original


How often should you descale a coffee maker?

If your coffee maker still works fine, there is no need to descale it. However, if you are having problems with it, descaling may help. The best way to descale a coffee maker is to fill it with white vinegar and water and run the coffee maker on a regular basis (2-3 times a week). This will help to remove any built up mineral deposits that may be causing the coffee maker to produce odd tasting coffee. See the link below for more information on how to descale a coffee maker.

What is the best way to descale a coffee maker?

The best way to descale a coffee maker is to firstly remove it from the power source and then give it a wash with mild dish-washing liquid, or soapy water and allow it to soak. Now, using the appropriate utensil of your choice, carefully unscrew and remove the filter which sits beneath the spout at the top of the machine. Then, using another utensil, gently scrape any debris off the walls of the machine. Finally, insert a tablet into the spout and run 2-3 cups of water through it until any excess grounds have been flushed down the drain. Finally, refill with fresh water and allow to brew again before serving.
