Why You Should Clean and Descale Your Coffee Maker

January 13, 2022

If you haven’t done so you should clean and descale your coffee maker. Until a couple of years ago, I didn’t know the difference between cleaning and descaling a coffee maker. And more importantly, I didn’t understand how essential it was to do both. Do you?

Isn’t Cleaning My Coffee Maker Enough?

Yes, you want a clean coffee maker, but cleaning alone isn’t enough. Here’s why. Coffee is naturally oily, and oils build up on carafes, brew chambers, and filter baskets. When this happens, your coffee will taste bitter, and eventually, the residue will clog the coffee maker, making it unusable.

Cleaning removes the oil residue created by coffee. However, cleaning doesn’t remove the mineral build-up. Descaling does. Minerals such as calcium and magnesium occur naturally in water. When these minerals pass through your machine, they slowly accumulate, especially on the makers’ heating units. If you’ve ever seen a chalky residue called limescale, which can build up on plumbing fixtures, that’s what clogs your coffee maker’s heating unit.

Eventually, the residue will affect the heating unit making it difficult to heat the coffee to the point where the coffee maker cannot extract the full flavor. You may even notice that your cup of coffee isn’t as hot as it should be. Eventually, the minerals will clog the machine and render it useless.

How Dirty Can it Be?

Not only can your coffee maker become clogged with residue, oils, and limescale, but it also can harbor germs and mold.

NSF International, the independent public health organization, found this in their International Household Germ Study.

“Yeast and mold are considered to have a negative impact on health since they may elicit an allergenic response in a certain percentage of the population. In 50% of the homes tested yeast and mold were found in the reservoir of the coffee maker.”
