The 5 Best Descalers


Descalers are a must-have if you have hard water in your area. Limescale can accumulate in your machine’s tubes, pumps, and inner workings over time. If you don’t descale, your brewer won’t work as well, so coffee takes longer to brew and it won’t taste as good. Regularly descaling can help remove mineral buildup to return your machine to like-new conditions, thereby improving performance.

A good descaler can make your machine work optimally again and can even extend the life of your machine, so you get a better value out of it. In most cases, you should use a descaler about once every three to six months to preserve your coffee maker.

What Are Descalers?

Descalers are chemical agents used to remove calcium deposits, limescale, and any other non-soluble sediments from any metal surfaces in contact with hot water. They release hydrogen ions when dissolved in water, which eat away at the scale and deposited minerals. They are commonly used to safely clean coffee and espresso machines, boilers, heat exchangers, water heaters, kettles, and septic tanks.

If you’re looking for a permanent solution, you won’t find better than the Eddy Water Descaler Electronic Water Softener. However, if you want something more affordable that you can use once a season, consider the options below.
