How to Clean Limescale from Your Coffee Machine: Easy Tips and Tricks

I love my morning cup of coffee. There’s nothing quite like that first sip of fresh, hot coffee to start my day off right. But recently, I noticed that my coffee just didn’t taste the same. It had a strange, bitter flavor that I couldn’t quite pinpoint. After doing some research, I discovered that limescale buildup in my coffee machine could be the culprit. Limescale is a hard, chalky residue that can accumulate in appliances like coffee machines, kettles, and even showerheads. It’s caused by minerals, like calcium and magnesium, that are present in tap water. Fortunately, there are easy tips and tricks to remove limescale from your coffee machine and restore its performance.

Why should you clean limescale from your coffee machine?

1. Enhance the flavor of your coffee

Limescale buildup can affect the taste of your coffee. When limescale deposits accumulate in your coffee machine, it can alter the flavor. Your coffee may taste bitter, dull, or even metallic. By regularly cleaning your coffee machine, you can ensure that your coffee has the rich and flavorful taste that you love.

2. Prevent damage to your coffee machine

Limescale can clog the internal components of your coffee machine, such as the heating elements and pipes. This can lead to decreased water flow, inefficient brewing, or even complete machine failure. By cleaning limescale regularly, you can prevent these issues and prolong the lifespan of your coffee machine.

3. Maintain optimal brewing temperature

Limescale buildup can insulate the heating elements in your coffee machine, preventing them from reaching their full potential. As a result, your coffee may not be brewed at the optimal temperature, leading to a weaker or less satisfying cup. By cleaning limescale, you can ensure that your coffee is brewed at the perfect temperature every time.

Easy tips and tricks to clean limescale from your coffee machine

1. Use white vinegar

White vinegar is a highly effective and affordable solution for removing limescale. Simply mix equal parts white vinegar and water and pour the solution into your coffee machine’s water reservoir. Run a brewing cycle as if you were making coffee, but without any coffee grounds. The acid in vinegar will break down the limescale deposits, cleaning your coffee machine in the process. Once the cycle is complete, run two additional cycles with clean water to rinse out any lingering vinegar taste.

2. Try citric acid

Citric acid is another natural and powerful option for cleaning limescale. You can find citric acid powder or pellets in most grocery stores or online. Dissolve a tablespoon of citric acid in a cup of warm water and pour it into your coffee machine’s water reservoir. Run a brewing cycle without any coffee grounds. The citric acid will dissolve the limescale and leave your coffee machine looking and tasting fresh. Remember to rinse your coffee machine with clean water afterward.

3. Use a descaling solution

If you prefer a ready-made solution, you can purchase descaling products specifically designed for coffee machines. These products often come in liquid or tablet form. Follow the instructions provided by the manufacturer to descale your coffee machine effectively. Descaling solutions are formulated to target limescale and are a convenient option for those who want a hassle-free cleaning process.

4. Scrub the removable parts

In addition to cleaning the internal components of your coffee machine, don’t forget to clean the removable parts, such as the water reservoir, filter basket, and carafe. These parts can also accumulate limescale. Use a mixture of warm water and dish soap to scrub away any residue. Rinse thoroughly with clean water before reassembling your coffee machine.

5. Prevent limescale buildup

Prevention is always better than a cure. To minimize limescale buildup in your coffee machine, consider using filtered or bottled water instead of tap water. This will reduce the mineral content and, subsequently, the chance of limescale formation. Additionally, descale your machine regularly as a preventive measure, following the manufacturer’s recommendations.


Cleaning limescale from your coffee machine is essential to maintain the quality and taste of your coffee. By using simple and easy tips and tricks like white vinegar, citric acid, or descaling solutions, you can easily remove limescale and prevent any damage to your coffee machine. Don’t forget to scrub the removable parts and consider using filtered water to minimize limescale buildup in the future. With a clean and well-maintained coffee machine, you can enjoy the perfect cup of coffee every morning, bringing joy and energy to your day.
