Drip filter coffee makers need to be cleaned monthly to remove hard water deposits (scale), leftover coffee oils that become rancid, and other impurities. Washing the pot just isn’t going to cut it: what about the internal components? Follow these steps to clean your coffee maker thoroughly and you’ll taste the difference.
- Make a mixture of 1 part white vinegar to 2 parts water– enough to fill the pot. For a stronger solution (which might be necessary if this is the first time you’ve cleaned your coffee maker since you got it years ago) make a mixture that is half vinegar and half water instead.
- Put a filter in your coffee maker, as usual.
- Pour the mixture into the coffee maker where you would normally add water.
- Turn the coffee maker on and let the mixture run completely through.
- Discard the filter and mixture.
Rinse the coffee pot.
Repeat all of the above twice, but this time with plain cold water. This will make sure all of the vinegar and water solution is completely gone.
