Well, all the water that passes through our coffee machine collects deposits.

This is a result of the process of heating water and its natural minerals. This process is called “limescale” and, in order not to have it develop into a problem you should perform descaling regularly.

How often do I have to descale my coffee machine?

It usually depends on how hard your water is and how often you use your coffee maker.

Usually in homes with hard water, you have to descale every 1-2 months. But if your machine is used a lot more often, then you may have to do it even more often. The descaling process is an easy one and doesn’t take long at all so, in fact, it’s not a big deal.

1.Using Vinegar


Vinegar is an acidic liquid that is made of water and vinegar. It descales and removes coffee stains. It can also remove lime-scale and mineral deposits that form in coffee machines, which is why it is used a lot by people who love drinking coffee.


  1. Fill half of your maker’s water reservoir with water.
  2. Add white vinegar until you fill the entire tank. It’s basically a 50/50 solution.
  3. Stir and start your decalcifying cycle.

2.Using Citric Acid

Citric Acid

Citric acid is an organic acid that is commonly used in food preparation as well as for cleaning purposes. It’s also one of the most common substances used to remove limescale from coffee makers because of its ability to dissolve calcium buildup on the water heating element of the machine.


  1. Mix 1.5 to 2 tablespoons of citric acid in a quart (1 liter) of warm water.
  2. Stir to dissolve the powder in the water.
  3. Add the solution to the water tank and start descaling according to the instructions, provided by your machine’s manufacturer (usually available in its booklet).

3.Using Baking Soda

Baking Soda

It is an alkaline powder that is made of sodium bicarbonate and water. It’s a good descaling agent due to its ability to remove coffee stains and other scale deposits in the coffee maker.


  1. Place 2 tablespoons of baking soda in a gallon (4 liters) of water.
  2. Stir the mix well and then turn on your machine.

4.Using Lemon Juice

Lemon Juice

Lemon juice is made from the juice of lemons and has acidic properties. It is also used to remove limescale from coffee machines, however, it’s not very effective in doing so as it doesn’t dissolve hard deposits and has shorter life compared to citric acid.

  1. Mix 1 cup (250 ml) of water with ¼ cup (60 ml) of lemon juice.
  2. Stir well to make sure that the citric acid will mix with the water.

5.Water Softeners

Water Softeners

If your home has a water softener, you should have some of the pellets for the system lying around. Softening pellets make it easier to filter out minerals and other particles that might otherwise.


  1. Just pour some in the tank, wait for a few minutes, and then run the coffee machine as usual.
  2. The pellets are coated with citric acid, which should dissolve upon contact with water. If not, add them to a bucket of water and wait for a few minutes. The pellets will dissolve after that. Pour the water into the tank and run your machine as usual.


If you want your coffee maker to run like new, a descaling solution is your answer. It’s a quick process, easy to do, and safe for your coffee maker.

It’s a nice way though, to make your coffee maker last longer because you don’t have to pay for prices for repair or cleaning the machine. It is very important to keep them clean all the time because if it is not properly cared for, the device will start to do damage and you will have problems with it.
