Clean a drip coffee machine using vinegar
Your standard drip coffee maker is a hotbed for germs. You shouldn't just clean it when your coffee flavor changes. Make sure you attack it once a month, at least if you use it every day.
One of the best ways to clean your coffee pot is by using white vinegar and water. This method has the benefits of being cheap, effective, and straightforward. To clean your coffee maker this way, follow these steps at least every third month:
- Empty your coffee maker – Throw away the paper filter and make sure there aren't any coffee grounds in your coffee maker when you start the sanitation process.
- Create a vinegar solution. Your coffee maker may come with instructions telling you what ratio of vinegar-to-water you should be using. If not, try a solution of one part vinegar to two parts water.
- Fill your water reservoir with it and start a brewing cycle, but DO NOT run it all the way.
- Stop the coffee maker when it is halfway through the brewing cycle and allow it to sit for at least 30 minutes, up to an hour.
- After 30 minutes to an hour, resume the brewing cycle, and allow it to finish.
- When the brewing cycle is complete, empty the carafe and filter and clean everything with hot tap water and dish soap.
- Fill the coffee pot with fresh water and pour it into your coffee maker's reservoir. Filter through three more brewing cycles, pouring out the old liquid and refilling the machine with clean water each time you start a new brewing cycle.
- Allow the device to stand for a few minutes between runs.
- After you've run the last brewing cycle, wash and rinse your coffee pot and filter basket either by hand or in the dishwasher. You can also use a mixture of baking soda, rice, and water to scrub the inside of the coffee pot if it has stubborn coffee residue or hard water stains.
- Wipe down the exterior of your coffee maker before putting it all back together.
- If you are worried that it will taste sour, just run a few more cleaning cycles for good measure. There is no sense in sacrificing coffee grounds to a cup that has a bitter taste because it still has white vinegar remaining in the system.
Descale a coffee maker without a vinegar solution
Are you sick of brewing coffee that has a vinegary flavor after you just cleaned it? Me too! One of the downsides of using white vinegar and water for purifying your coffee maker is that it can leave a vinegary taste in the machine for days.
If you'd like to avoid this, follow the same procedure as above, only use one of the many commercial descaling products on the market, such as this one or this one.
Alternatively, the instructions on the product should give you some ideas on how to maintain your coffee machine, usually recommending you purchase their preferred descaling product.
Note: It's not a good idea to clean coffee makers with bleach or other strong chemicals that aren't food-safe. Stick to white vinegar and water or products made especially for cleaning coffee makers to avoid ingesting toxic chemicals in your next cup.
Clean a drip coffee maker using CLR
Yes, you can use CLR (Calcium, Lime, and Rust Remover) to get a clean coffee maker. However, you cannot use CLR in a machine that leaves liquids remaining in one location, such as a French press or cold brew coffee maker. I only recommend going this far if nothing else works. If you are on month 36 of owning your coffee machine, maybe this is the best option for you.
Here's what you need to know for drip coffee makers:
- Make a mixture of one part CLR to eight parts tap water.
- Remove all coffee grounds from the machine.
- Add the solution to the reservoir and run a complete brew cycle.
- Wait 30 minutes.
- Dispose of the solution, refill the reservoir with fresh water and filter out the remaining liquid for at least two or more brew cycles.
- Rinse the exterior and wipe it down with a cloth before using it again.
