Cleaning Vs. Descaling

Regular cleaning of equipment and tools used to make coffee is critical to avoid bacteria, germs, and unwanted tastes. To prevent contamination and make your coffee machine last longer, you need to wipe down the machine after brewing, handwash it every day, and descale once a month.

Cleaning your coffee machine must be done daily. Cleaning includes throwing out used grounds and filters, wiping out coffee residue, and drying the water reservoir. You should also wash all the detachable parts with hot water, soap, and a sponge or coffee brush to scrub away germs and coffee oils buildup. 

On the other hand, descaling is a process of removing mineral build-up. It’s usually done every three to six months, but it can also be monthly. 

Water minerals such as calcium and magnesium accumulate in the heating element, damaging the coffee maker and resulting in less flavorful coffee. You can combine vinegar and water in the chamber, place a new filter, and run a cycle twice to descale your machine.
