Starting at the very beginning, and a question raised by our avid reader, Maddison was about the safety of using undiluted bleach to clean her coffee maker.
I can tell you absolutely with 100% certainty that using undiluted bleach and diluted bleach is safe, with the caveat that you rinse your coffee machine well afterwards with a plenitude of water.
Some people claim that it is unsafe. I have personally cleaned my coffee brewing equipment with both diluted and undiluted bleach many times with no adverse effects.
Is It Safe To Use Undiluted Bleach To Clean A Coffee Maker?
To emphasize the point, if you are going to clean your coffee making equipment with bleach of any kind, diluted or undiluted or any other cleaning solution, it is only safe to do so if you rinse your gear with an abundance of water.
Besides the health issue, it is also a matter of not brewing up your next few batches of coffee with an off or rotten taste.
How To Clean A Coffee Maker With Bleach Step By Step
Cleaning your coffee maker with bleach is easy. The process is exactly the same as any other cleaning agent, be it white vinegar, baking soda (Bicarbonate of soda).
Let’s crack on with this and talk about the equipment and materials needed.
There is no special equipment required other than a soft cloth, rubber gloves, bleach and plenty of water. In all probability, you already have all that you need in your kitchen.
Step 1: Prepare Your Machine.
First, prepare your machine by dipping a soft cloth or sponge in bleach and wipe clean the exterior. Remove the drip tray and wipe clean and rinse your drip tray.
Use a large container and place it below the nozzle where your coffee comes out and run 2 to 3 brewing cycles of hot water only. If you must, put it in an empty reusable pod.
This is to clear out any easy to clean water soluble grime in your pipes.
Don’t forget to wipe clean the inside and outside of your water tank.
Step 2: Cleaning The Inside Of Your Machines.
Now fill your water tank with bleach and carefully run a brewing cycle over and over again until your water tank is empty. Be sure to use an ample container to catch your used and dirty bleach.
Step 3: Rinse Your Machine.
Start by rinsing your water tank well and filling it with hot water 3 to 5 times to flush and rinse your machine by running brew cycles until it is empty each time.
Run another rinse cycle with warm but not hot water and fill your tank 3 to 5 times and run as many brew cycles as needed to empty your water tank each time. Follow up by running another 3 to 5 water tanks full of cold water.
It is absolutely imperative that you rinse your machine of the undiluted beach and the scent of it.
Step 4: Dry run time!
Fill your clean and ready water reservoir with clean cold water and “brew” a cup of water. Sniff test the water for any traces of bleach and cautiously sip test the water.
If it passes both tests, you are ready to brew a test cup of coffee.

Why Does Your Coffee Maker Need To Be Cleaned?
As a fellow coffee lover you want to enjoy the best possible cup of coffee every single time. As your coffee machine gets dirty, the quality of your coffee reduces. It is a kin to drinking coffee from a dirty mug.
there is the health issue. A 2011 study by NSF found that there are more germs and bacteria in your coffee maker reservoir than a toilet seat. I bet that grabbed your attention.
Unfortunately, your coffee machine is a breading area for mould and all kinds of germs.
Why Use Bleach?
While the use of bleach might alarm you, it is not at all dangerous or harmful if you are using it correctly. Bleach, as you know, is a very powerful disinfectant.
Did I mention there are more germs in your machine than a toilet seat?
Now you know why using bleach to clean your coffee maker is a very good idea!
What Is The Best Way To Clean The Inside Of A Coffee Maker?
The best way, in my humble opinion, is to follow the above step-by-step process, but instead clean your coffee maker with vinegar.
Distilled white vinegar is the best alternative to bleach and gets your machine just as clean and has antibacterial properties and kills germs.
Can A Dirty Coffee Maker Make You Sick?
Unfortunately, yes, a dirty coffee maker can make you sick.
Coffee machines of all types produce the perfect environment in which bacteria and mold will grow. Where you see a small bit of mold, there are, and will be a lot more in places that you can’t see inside your machine.
And that is what can, and will make you sick.
How Often Does Your Coffee Maker Need Descaling?
I advise that you clean and descale your coffee machine at least once every week or two. For better coffee quality and as a preventative maintenance routine I suggest that you use a water filter or use a commonly available water filter jug and use that to fill your water reservoir.
Regardless of your water situation, be it soft water or hard water, using a filter will help to prolong the life of your machine and improve the quality of your coffee.
