How to Descale a Coffee Kettle
Not quite. Water contains minerals like limescale and magnesium that adhere to metal surfaces, like kettles. Over time, these minerals accumulate into a sizable amount of scale buildup and create problems with your kettle.
This is especially true if you live in an area with hard water, meaning there are higher amounts of these minerals in the water. The ideal measurement of minerals in water for coffee brewing is between 75-250 parts per million (PPM), according to the Specialty Coffee Association. But average tap water ranges between 100-400 PPM, leaving households with hard water at a greater risk for accelerated buildup.
But for all water types, the presence of scale inside of your kettle will reduce efficiency of the boiler and hamper its ability to heat the water to its optimal brewing temperature. Water should be heated to between 195-205 degrees Fahrenheit (or 92-96 degrees Celsius) to achieve the tastiest flavors in brewed coffee. But if your kettle can’t reach that temperature target, the result will be a flat, under-extracted and sour tasting coffee. And after enough scale has accumulated, your coffee won’t even be hot enough to enjoy.
But with a little preventative maintenance, your kettle will be in top shape to help you brew a consistently balanced and delicious cup of coffee.
The process of removing scale buildup from kettles, drip coffee brewers and espresso machines is called, naturally, descaling. This is a different process than cleaning the coffee residue and oils from a coffee machine. Using an alkaline-based product like Cafiza, will completely remove this coffee grime from portafilters, carafes and valves of a coffee or espresso machine. But descaling calls for an acid-based formula to eliminate scale buildup.
Descaling Your Kettle
Instead, we’ve formulated a product that’s built for the job. Dezcal is proven to remove the toughest scale buildup from kettles, espresso machines and drip coffee makers without damaging the equipment. It’s formulated with non-toxic, biodegradable and safe ingredients. Dezcal also cleans and rinses away faster than vinegar.
Descaling your kettle with Dezcal is simple. Just pour the Dezcal solution directly into your kettle and add the specified amount of water to create a descaling solution. Then allow the solution to sit in your kettle for up to 30 minutes. Finally, discard the descaling solution and rinse the kettle with clean, cold water before using the kettle again.
No scale left in your kettle. No damage to your equipment. And no grody odors or foul tastes in your coffee. Dezcal is the right product for descaling a kettle, coffee brewer or espresso machine, allowing you to simply enjoy a delicious cup of coffee, scale-free.
