How to Descale a Single-Cup Coffee Maker

May 3, 2023

How to descale a single-cup coffee maker is essential to know if you want a great tasting cup of coffee and you want your machine to last. Coffee fans love the convenience of their single-serve machines. You don’t have to bother with paper coffee filters, washing a glass carafe, or measuring coffee. These coffee makers do need a little TLC sometimes, though. Because inside of that single-cup machine, mineral deposits are accumulating on the heating element, which affects both water flow and proper brewing temperature. With time, those mineral deposits can destroy your machine.

Use Bar Keepers Friend Coffee Maker Descaler to remove crusty deposits from your single-cup coffee maker every three months (or sooner, if you notice the coffee flow seems slower). It’s an easy way to get the most life out of your coffee maker.

Protect Surfaces

Bar Keepers Friend Coffee Maker Descaler contains specifically selected acidic ingredients that get rid of harmful mineral deposits inside your single-cup coffee maker. 

Pro Tip: The acidic ingredients can potentially harm delicate finishes. If you have marble, granite, or other natural stone countertops, cover them before you start descaling.

Isn’t Cleaning it Enough? Why Do I need to Descale It?

You need to descale your pot because although cleaning removes the oil residue created by coffee it doesn’t remove all the mineral build-up. That’s what descaling does. Calcium and magnesium occur naturally in water and they build-up in your coffee maker.   

Depending on how often you use the machine and how much mineral content is in your water in as little as a couple of months the residue can and will hinder and damage the heating unit. You may notice that your cup of coffee isn’t as hot or as flavorful as it should be.  Eventually, the minerals will clog the machine and render it useless.

How to Descale a Single-Cup Coffee Maker

Remove any coffee pod from your coffee maker, and make sure the reservoir is empty. Fill your carafe with cold water, and put on protective gloves. Place a ceramic mug under the discharge (ideally, a cup with the same capacity as your machine’s largest cup-brewing volume).

Fill the reservoir with cold water, adding one ounce of Bar Keepers Friend Coffee Maker Descaler for every eight ounces of water. Initiate the brew cycle; you will need to repeat this step several times to completely empty the reservoir.

After the reservoir is empty, fill it with cold water and initiate the brew cycle to rinse the inside of the machine, repeating the brew cycle until the reservoir is empty again. Add fresh water before brewing your next cup.

Caring for Your Machine

It doesn’t take long to descale a single-cup coffee maker, and it’s time well spent – regular descaling helps keep your machine in tip-top shape. Once descaled, use Bar Keepers Friend Coffee Maker Cleaner to remove oily residue that can harm your machine. Use Bar Keepers Friend coffee maker maintenance products at least every three months, to get rid of grime and build-up. Always refer to your owner’s manual before descaling.
