6 Simple Steps To Descale Your Coffee Maker

Whether you have a drip coffee maker or a Keurig one, the cleaning or descaling process is quite similar. The only difference is that you have to remove the K-cup while descaling your Keurig coffee maker. On the other hand, for a drip coffee maker, you have to take the filter out of the machine.

The below steps will show you how to descale the mineral build-up from your coffee maker.

Decide What Descaling Ingredient You Want To Use

Before starting the cleaning process, you must decide which ingredient to use to clean the coffee maker. Generally, white vinegar is one of the most popular and effective ingredients for descaling. It consists of acetic acid that dissolved minerals inside the coffee maker.


However, you might not be a fan of vinegar as it has a strong smell. So, instead of vinegar, you can use lemon juice, baking soda, or any store-bought descaling powder or citric acid powder. Lemon juice contains citric acid that helps break the mineral deposits.

So, choose a descaling ingredient beforehand.

Make The Descaling Solution

After you have decided which ingredient to use, make a descaling solution with that ingredient. Fill the carafe with 50% vinegar and 50% water if you want to use vinegar.

For the lemon juice, take two lemons and squeeze out the juice to mix with water. After mixing the lemon juice with water, you will have a citric acid solution.


In the case of baking soda, mix  one-fouth cup of baking soda with one cup of warm distilled water. If you are using descaling or cleaning powder, then mix the powder in 32 ounces of warm water.


Note: Never use two descaling solutions at a time. Choose any one solution for descaling. Also, avoid using boiling hot water to clean your coffee maker, as it can defile the boiler.

Go Through A Brewing Cycle

Fill the water reservoir with the cleaning solution you made and turn on the brewing cycle. Wait till the brew cycle finishes completely. When the cleaning solution moves through the coffee machine, it breaks up the minerals and coffee oil residue, pushing them to the spray head.


The brewed solution will get stored inside the carafe. You might observe some white chalky flakes if the water in your region is hard. Otherwise, the solution will become foamy after the cycle.


Note: Some coffee makers come with a pre-set cleaning cycle. Check the user’s manual if you have one of those coffee makers.

Rinse The Coffee Maker

After the cleaning solution has been brewed through the coffee maker and stored in the carafe, throw away the solution. Fill the coffee maker’s reservoir with filtered water and re-run the brew cycle. Keep repeating the process until you think the descaling solution has rinsed off completely.


Note: Running the brewing cycle twice with filtered water is enough to rinse off the solution.

Wash The Coffee Pot And The Brew Basket

Mix liquid dish soap with hot water to wash the coffee carafe and the brew basket. Soaking the coffee pot in hot soapy water will remove the coffee stains.


After soaking them in soapy water for a few minutes, scrub them with a soft cloth. After scrubbing, rinse them with tap water.

Wipe Or Clean The Water Reservoir

The inner part of the water reservoir might contain some mineral content. So, take a microfiber cloth and use it to wipe inside the reservoir.

How Frequent One Should Descale A Coffee Maker

If you are a regular coffee maker user, it is best to go through a descaling process once a month. 


However, this descaling frequency depends on many factors. Sometimes due to excess minerals in the water, some people find the necessity to descale a coffee maker thrice a month.


Now, the question is how to know the time has come for deep cleaning. If you observe a few factors, you can easily determine that the coffee maker requires deep cleaning. When you find the signs below, prepare to describe your coffee pot or machine.

Chalky White Residue

Should I remove the filter before descaling?

What is the best natural descaler?

White vinegar is a coffee maker’s most common and effective natural descaler. Fill the carafe with water and vinegar in equal portions and run the solution through the cycle. It will help to descale the mineral build-up from the machine.

Does coffee taste bitter after descaling?
