There are dozens of “proprietary” descaling products on the market and how on earth do you find out which one will perform as claimed? Well, it’s pretty simple. You need to have enough citric acid, lactic acid, sulfamic acid, or acetic acid (vinegar) in the solution to effectively break down limescale and/or mineral deposits in your coffee or espresso machine.
The most well known of the bunch is vinegar (acetic acid) but many find their machines aren’t effectively cleaned by this method. Part of the reason is that vinegar actually has a relatively low concentration of acetic acid and in order to be as effective as other products, namely citric acid, the concentration would release fumes that can potentially harm your respiratory tract. I love vinegar for cleaning and the smell doesn’t bother me at all, but for descaling I use citric acid 100% of the time.
In fact citric acid is so prevalent today you’ll find it in pretty much everything as a preservative, flavor enhancer, booster, or cleaning agent. It’s especially popular in dishwashing tablets and toilet cleaning products, along with descaling products. It’s a main ingredient in bath bombs and yet citric acid is still not commonly found in stores or niche markets. Very interesting development indeed.
Below are some of the popular descaling solutions we’ve found, and we’ll keep adding to the list.

Need to remove mineral buildup and/or limescale in your coffee maker? A descaling solution is the answer. Cleaning regularly is crucial to remove limescale and bacteria buildup, ensuring better health and taste. In this guide, we’ll review the top solutions to help you choose the best one for maintaining your machine.
Vinegar, which contains about 5% acetic acid, is a natural and affordable option for descaling. However, it’s not the best for “hard water” areas and you may require something a little more potent such as a citric acid, sulfamic acid or lactic acid based product.
Introduction to Descaling
Descaling is an essential process for maintaining the performance and longevity of coffee machines, including Keurig, Nespresso, Breville, Mr. Coffee, Oxo, Gagia, and other machines. When hard water is used in coffee makers, mineral buildup, also known as limescale, can occur. This buildup can lead to a decrease in coffee taste and machine efficiency. Regular descaling helps remove these mineral deposits and prevents corrosion, ensuring that your coffee machine continues to produce great-tasting coffee. By incorporating descaling into your routine maintenance, you can keep your coffee maker in top condition and enjoy a consistently delicious brew. It’s not complicated or expensive and we’ll help point you in the right direction.

Characteristics of a Great Cleaner
A great coffee machine cleaner should excel in several key areas to ensure your coffee maker remains in top condition. Firstly, it must be highly effective at removing mineral buildup and limescale, which can significantly impact both the taste of your coffee and the performance of your machine. Cleaners that utilize citric acid or white vinegar are particularly adept at breaking down these deposits, making them popular choices among coffee enthusiasts.
Ease of use is another crucial characteristic. A great cleaner should require minimal effort, allowing you to maintain your coffee machine without hassle. This convenience is especially important for daily coffee drinkers who want to keep their machines in optimal condition with minimal downtime.
Safety and environmental friendliness are also important. Non-toxic and biodegradable cleaners ensure that the descaling process is safe for both home and office environments. Citric acid and white vinegar are excellent examples of such cleaners, as they are both effective and gentle on your machine.
Affordability is another factor to consider. Cleaners that are cost-effective and provide multiple uses from a single bottle offer great value. Universal descaling solutions that work with a variety of coffee machines, including Keurig and Nespresso, are particularly advantageous as they eliminate the need for multiple products.
When selecting a cleaner, it’s essential to consider the type of coffee machine you have. Some cleaners are specifically designed for certain types of coffee makers or espresso machines, so always check compatibility to ensure optimal results.
Impresa Descaling Solution – Best for Budget
Price: Affordable
Pros:
- Cost-effective with 2 uses from a single bottle.
- Easy to use and effective in cleaning. This great cleaner is perfect for various tasks.
Cons:
- Initial brew after descaling can appear soapy.
The Impresa Descaling Solution was a game-changer for my Keurig, resolving significant dispensing issues effectively. The descaling process was straightforward: pour half a bottle into the reservoir, fill with water, run a brew cycle, let it sit for 30 minutes, dump the pot, and run two more cycles with clean water. You can use a carafe to measure equal parts of the descaling solution and water. Initially, the water looked like soapy bath water, but soon, it resulted in a squeaky clean reservoir and clear water.
Despite its initial soapy appearance, the Impresa Descaling Solution is both affordable and effective. The first cup of hot water dispensed after using the solution had no aftertaste, highlighting the product’s safety and efficiency. It leaves no residue, keeping your coffee’s taste unaltered. This solution can dissolve especially beneficial for those on a budget, providing multiple uses from a single bottle.

Urnex Dezcal – Best for Professional Use
Price: Moderate
Pros:
- Highly effective in clearing mineral buildup.

This product is a staple in many office environments and cafes, where maintaining the highest level of machine performance is crucial. Using a keurig descaling solution can further enhance the longevity of your coffee maker.
While using it, I found it effectively removed any accumulated mineral deposits. The fine texture of the Dezcal powder can float into the air, similar to powdered sugar, but it dissolves well in warm water, enhancing the cleaning process. Users figured the product was improving the cleanliness of their coffee machines after multiple brew cycles. The only issue was the descale indicator light occasionally not turning off afterwards. Despite this minor hiccup, Urnex Dezcal remains a top choice for professional use, ensuring your coffee maker stays in optimal condition.

Homemade Descaling Solutions
Homemade descaling solutions offer a cost-effective and environmentally friendly alternative to commercial cleaners. One of the most popular options is white vinegar, which, when mixed with water, creates a powerful solution for removing mineral buildup and limescale. Another effective ingredient is citric acid, a natural and non-toxic cleaner found in many household products.
To create a homemade concoction, simply mix white vinegar or citric acid with water in a container. For white vinegar, a common ratio is one part vinegar to one part water. For citric acid, dissolve one to two tablespoons in a quart of water. Pour the mixture into the coffee machine’s water reservoir and run a brew cycle. Allow the solution to sit in the machine for about 30 minutes to effectively break down any mineral deposits.
After the solution has done its work, rinse the machine thoroughly with clean water by running several brew cycles. This step is crucial to ensure no residual taste or smell affects your coffee.
Homemade descaling solutions are versatile and can be used for various coffee machines, including Keurig and Nespresso. They are an excellent way to save money and reduce waste while keeping your coffee maker in top condition.
How to Use Descaling Solutions Effectively
Using a universal descaler effectively is simple if you follow a few key steps. Start by checking the solution manufacturer’s instructions. For example, a common dosage is 1 ounce of descaler per 32 ounces of water. If you’re using a powder you may have to dissolve it in warm water before pouring it into the machine.
Once the solution is ready, begin the descaling process by filling the water reservoir with the solution and water. Start a brew cycle and let it run. Depending on the product, you may need to let the solution sit for a period to break down the mineral deposits effectively. For example, white vinegar requires more time, and may need 30+ minutes to break down limescale.
After the initial brew cycle, dump the pot and rinse the machine by running two more cycles with clean water to ensure no residue is left behind.
Repeating the rinsing steps ensures that your coffee maker is thoroughly cleaned and ready for use. Following these steps helps maintain your machine’s performance and ensures great-tasting coffee every time.
Benefits of Regular Descaling
Regular descaling offers numerous benefits that enhance your coffee-making experience. One of the most notable benefits is the significant improvement in the speed of brewing, indicating better water flow through the machine. This means less waiting time for your morning cup of coffee.
By removing mineral deposits, descaling restores your coffee maker’s performance and extends its lifespan by preventing damage to heating elements and corrosion. Users also notice a significant improvement in coffee taste after descaling, with no lingering aftertaste from the solution.
Regular descaling maintains optimal brewing temperatures, enhancing flavor extraction from coffee beans and ensuring the best taste. Additionally, regular descaling can prevent scale-related damage, ensuring your coffee maker stays in top condition for longer. Regular descaling also helps prevent the growth of bacteria in the water reservoir, ensuring both the health and taste of your coffee.
A well-maintained coffee maker produces hotter coffee, ensuring a more enjoyable drinking experience. Regular descaling keeps your coffee makers in top condition, ensuring great-tasting coffee every time.
Frequently Asked Questions
How often should I descale my coffee maker?
You should aim to descale your coffee maker every month if your water is hard, or 3 months if you have softer water. Regular descaling also helps prevent mold growth in the water reservoir, ensuring the health and taste of your coffee.
Can I use vinegar as a descaling solution?
Absolutely, vinegar works great for descaling! Just mix it with water, start the brewing process until liquid starts to exit the machine and turn it off, let it sit 10 -15 minutes, restart to finish, and rinse it out—easy peasy! Vinegar, specifically white vinegar, is a popular household item known for its acidity, which effectively breaks down mineral deposits. It’s a cost-effective alternative to commercial descaling solutions and is readily available in most homes. When using vinegar, it’s important to ensure that the solution is thoroughly rinsed out to avoid any lingering taste or smell in your coffee. While it does work, it may take a few rinse cycles to get rid of the residual smell and taste. Additionally, vinegar is a natural and environmentally friendly option, making it a good choice for those who are conscious about using chemical-free cleaners in their appliances. It’s always a good idea to check your coffee maker’s manual to ensure that vinegar won’t harm any specific components of your machine.
What are the signs that my coffee machine needs descaling?
If your coffee maker is brewing slower, your coffee taste is off, or you see dark or white buildup in the reservoir or coffee pot, it’s time to descale. Visible mineral stains on the coffee maker are a clear indication that descaling is needed. Keeping it clean will help you enjoy better coffee!
When does my hot water kettle or dispenser need descaling?
This is pretty obvious. If there’s an excessive buildup on the inside of the kettle or dispenser than clean it. Don’t try to scrub it, but rather use citric acid or vinegar to break down the deposits. Scrubbing will just result in a scratched interior. Halefresh specifically refers to kettles and dispensers on their bottle.
Is it safe to use solutions on all coffee makers?
They’re safe to use on all coffee makers, but always check your manufacturer’s recommendations first to see if there are any specific instructions. While vinegar is a popular option it’s definitely the best one, and the smell might stick around after thorough rinsing.
Can the taste of my coffee be negatively affected?
Absolutely, if you don’t rinse out the machine well, it can mess with your coffee’s taste. Regular descaling helps maintain the quality of your coffee by preventing mineral buildup that can affect the taste. Just make sure to follow the rinsing instructions to keep your brew delicious!
