How to Descale a Coffee Machine

Since we know what does it mean to descale a coffee machine, now how do you descale a coffee machine and what can I use to descale my coffee machine? Let's follow the steps below to effectively descale your coffee machine.

Gather Your Supplies

Before starting the descaling process, you should be clear about what to use to descale coffee machines. Gather all the necessary supplies which may include warm water, mild soap, a soft cloth, and remember to access your coffee maker's user manual for details.

Prepare the Descaling Solution

Some descaling solutions do help a lot in cleaning and descaling the coffee maker. So what can I use as a descaler for coffee machines? Some popular options are vinegar, citric acid, or commercial descalers. If you're using white vinegar, mix equal parts vinegar and water in the coffee maker's water reservoir. For a commercial descaling agent, follow the instructions on the package to prepare the solution. Ensure the carafe is empty and the grounds have been removed from the chamber.

Run a Brewing Cycle

Start a brewing cycle using the descaling solution prepared in the previous step. Let the coffee maker complete a full cycle by using the specified quantities of descaling solution and water. You should also refer to your machine's user manual for any specific instructions regarding the descaling process.

Turn Off Indicator Light

If your coffee maker features a Cleaning Needed Indicator light, check if it's still illuminated after the brewing cycle. If the light persists, repeat the brewing cycle until the indicator no longer turns on after brewing. This ensures that the descaling process effectively removes mineral buildup.

Rinse and Repeat if Necessary

After completing the descaling cycle, rinse the coffee maker by running it through two brewing cycles with a full carafe of fresh, cool water each time. This helps to remove any residual descaling solution and vinegar odor from the machine. Repeat the rinsing process if necessary until the water runs clear.

Wash Brew Basket and Carafe

While the coffee machine is rinsing, clean the brew basket and carafe with hot, soapy water. Use a soft cloth to ensure thorough removal of coffee residues and mineral deposits. Rinse the basket and carafe with hot water and let them air dry completely.


Reinstall Water Filter

After cleaning and drying the coffee maker and its components, install the water filter back or replace it if necessary. Keep the lid open to allow the filter to dry properly before using the coffee maker again.

Tips for Preventing and Maintaining Your Coffee Machine

To keep your coffee machine running smoothly and ensure a consistently great cup of coffee, please also follow these helpful tips:

1. Use Filtered Water: Using filtered water can reduce mineral buildup in your coffee machine, prolonging its lifespan and preserving the taste of your coffee. Refrain from using distilled water, as it may lead to metal corrosion in some coffee machines.

2. Clean Regularly: Clean your coffee machine daily to remove coffee splashes, oils, and residues. This prevents them from accumulating and affecting the performance and flavor of your brew.

3. Descaling Frequency: Determine how often you need to descale your coffee machine based on the hardness of the water in your area and your machine's usage. In general, aim to descale your machine about once a month if you brew coffee daily. Or, pay attention to indicator lights and descale your coffee machine promptly when necessary.

4. Follow Manufacturer's Instructions: Refer to your coffee machine's user manual for specific maintenance guidelines and descaling instructions. Following the manufacturer's recommendations ensures proper care and prolongs the life of your machine.

5. Consider Water Filters: Consider using water filters to reduce mineral concentration in your coffee machine. These filters remove contaminants and help prevent mineral buildup.
