Use only a mild dish soap to clean the parts of your coffee maker. Harsh dish soaps with lots of chemicals have a tendency to leave a film on everything, and we don't want to be ingesting that with our coffee.
To clean the carafe and the water reservoir, scrub with a bottle brush. If you have build-up that's hard to remove on the bottom of your carafe, then let it soak in a mixture of white vinegar and water for a few hours.
Let your washed coffee maker parts dry off in a drying rack or use a towel to dry them.
Using one-part vinegar to one-part water, fill your water reservoir until nearly full.
If you don't have a removable water reservoir, then you'll measure this in your carafe and pour it into your reservoir.
Put your coffee maker back together, and make sure that your reservoir is full of your vinegar/water mixture.
Now you'll want to run the vinegar/water mixture through your coffee maker to descale it. If your coffee maker does not have a "Clean" function like mine, then you can simply brew as you would coffee.
- Press "Clean" or "Brew."
If you're using a "Clean" function, then this could take up to one hour.
If you're using "Brew":
- Let mixture run for a few minutes.
- Unplug coffee maker to allow the mixture to sit inside for a while.
- Let sit for a half-hour.
- Turn back on to finish brewing.
Once you've let it run through the "Clean" cycle or brewed twice, dump out the mixture in the drain.
Fill your water reservoir with water and put it back in your coffee maker. If your water reservoir isn't removable, then use your carafe to fill it.
Run your coffee maker's brew cycle to let the water run through and clean out the vinegar.
Repeat steps 10 and 11 at least one more time - or until you don't smell vinegar in the brewed water anymore.
