If you’re a regular coffee drinker, you should learn how to use citric acid to clean a coffee maker. You most likely wash your coffee pot regularly with soap and water, but simply using water leaves residue inside even the best coffee makers. In many cases, the residue left behind contains calcium, magnesium, and limestone, especially if you have hard water. Professionals refer to this process as descaling, but it helps with mold and bacteria as well. To reduce build-up in your coffee machine, you should clean a coffee maker with apple cider vinegar or citric acid.
The process for descaling a coffee maker requires a substance that can cut through the various minerals found in water, including vinegar, citric acid, or a commercial descaler. The process for each of these options remains the same, so it comes down to your preference and what is easier to find.
If you have a coffee machine with an indicator light, it will tell you when you need to descale your machine. If you don’t have an indicator light, watch for a chalky white residue, which shows the build-up. If you’re wondering, can you use bleach to clean your coffee maker? You can, but maybe you shouldn’t.
You can find citric acid at the grocery store to use for descaling your coffee machine.
You should try to avoid the irritating bleach when cleaning your coffee maker, but you may use vinegar or citric acid instead.
Should you use vinegar to clean coffee makers?
You may choose plain or white vinegar to descale your coffee products, but ensure your mixture contains roughly one-half vinegar and one-half water. When doing so, follow the method described above since citric acid and vinegar can be swapped for each other.
Is it important to clean the outside of my coffee maker?
Yes. As with any surface in the kitchen, your coffee maker’s exterior should be cleaned occasionally. You should wipe it down every three to six months, with frequent coffee drinkers cleaning it more often.
How often do I really need to clean my coffee maker?
You should clean your coffee maker every three to six months, but this frequency depends on your coffee consumption from the machine and the water in your area. For example, if you have hard water full of minerals, you could need to clean your coffee machine every month.
STAT: The biggest misconception identified through the study was that the bathroom is the dirtiest place in the house when in fact the kitchen had the most germs. (source)
