Confession: I never used to clean my coffee machine. The truth is that I hadn’t really thought about cleaning my coffee maker until I saw a video on TikTok about all the grime that can build up if you don't clean it. It was enough to put me off ever using my espresso machine again *shudders.* 

The unfortunate reality is that if you’re someone who habitually starts their day with coffee (I mean, who doesn’t?) you should probably think about giving your machine a good ol’ clean. Because the gunk builds up hella fast. 

You might assume that all it takes to clean your machine is to give the exterior a little wipe and polish to keep it shiny, streak-free, and looking pretty. But that’s not enough, because it’s actually the inside of your coffee machine that needs the most care.

There is some good news though, and that’s how easy it is to clean your coffee maker. Whether it’s an espresso maker, a pod machine, or a French press, all you need to give your machine a deep clean is a sprinkling of baking soda.

Good to know

Time: 10 minutes 

Difficulty: Easy  

Helpful hints: Every coffee maker is different. Make sure to check the user manual or brand website to ensure you won't harm your machine or ruin the warranty.

Here’s what you’ll need

How to clean a coffee maker with baking soda

Step 1: Empty the tank on your coffee maker

The first step is to empty out the water tank on your coffee maker so that it’s completely empty. 

Step 2: Fill a jug with warm water 

Top up an easy-pour jug with warm water. 

Step 3: Add baking soda to the water 

Then, add ¼ cup of baking soda to the water and mix it in.  

Step 4: Pour the mixture into your coffee maker

Next, pour the baking soda and water mixture into the water tank of your coffee machine. 

Step 5: Run the mixture through the machine 

Turn on the coffee maker and run the baking soda mixture through the machine until the water tank is empty.  

 Step 6: Flush the machine out 

Wash out the water tank and refill it with fresh water. Then, run the fresh water through the machine until the tank is empty and the water runs clear. 


How frequently does my coffee maker need cleaning?

How often your coffee machine needs to be cleaned depends on how often you use it. The more frequently you use it — and the more water you run through it — the more often it will need cleaning. It's also worth noting that how often your coffee machine needs cleaning will depend on the type of machine and the manufacturer's advice. 

What are the signs that my coffee machine needs cleaning?

One tell-tale sign that your coffee maker needs a clean is your coffee tasting bitter or just not quite right. Another sign to look out for is evidence of limescale or mineral deposits building up within your machine.
