Which coffee machine do you prefer? Keurig? Chemex? Drop maker? Aeropress? Nespresso? French press? Maybe you prefer a cold brewer? As many types of coffee makers are out there, there are ways to clean them too. To get the most flavor (and the least amount of old coffee residue) in every cup of joe, follow the cleaning methods outlined in the video above.
But first a note about coffee filters. We have previously covered how useful they are for cleaning your whole house. Always empty the used filter in the trash before cleaning the coffee machine, as coffee grounds can clog a sink.
Limescale deposits form in filter coffee machines if they are not cleaned regularly. Fortunately, white vinegar is ideal for getting rid of them.
Fill the water chamber with equal parts water and white vinegar. Brew half a pot, then stop brewing and let the maker cool for an hour. This allows the vinegar to act on any residues in the machine. After an hour, brew the rest of the pot, discard the vinegar solution, and brew another full pot with clean water.
To clean the pot yourself, you can put it in the dishwasher or a magic eraser.

Also known under the brand name Chemex, these glass canisters are easily discolored. Simply fill up with warm water and dissolve two effervescent tablets (like Alka-Seltzer) in it. Then rinse and dry.
Since you have to sit for several hours to extract the taste of the coffee, these tall jugs (whether made of plastic or glass) can easily turn brown. For a glass cold brewer, repeat the same method that you used for pouring over. For plastic, pour in ice, dish soap, and rock salt and shake it to remove stains. Alternatively, you can use soapy water and rice for the same effect.
Whether you have a Keurig or a Nespresso, the process is the same. Remove the capsule and fill the water chamber with white vinegar. Keep brewing cups until the chamber is empty. Then fill the chamber with clean water and brew another cup.
This couldn’t be easier. Fill half with soapy water and dip up and down. Then just rinse and dry.
Don’t use soap or scrub too hard. You want the oils in the coffee to flavor the inside of the pot. Let the jug cool down after each use and empty the coffee grounds. Take the pieces apart and run them under warm water, then dry with a microfiber cloth.
