Coffee Maker Cleanser: Coffee makers are a breeding ground for mold, so they should be thoroughly cleaned every 2–3 weeks for drip or pod-based machines. You’ll also be cleaning off buildup from hard water, which isn’t harmful, but can clog your machine. Vinegar will do the trick nicely here, and adding a bit of baking soda to the vinegar and hot water helps clear away any coffee stains on glass or plastic.
Fill the water reservoir halfway with white vinegar. Use a soft bottle brush to swish this around to get into all of the crevices of the water reservoir and clean them. Then use the bottle brush dipped in vinegar to clean the area where the filter or coffee pod goes. You may also need to get a cotton swab out to reach the smaller spaces that will also be covered in coffee film and dust. Rinse the bottle brush or cotton swab with water and go over all of these areas again with the brush dipped in clean water.
Next, finish filling the water reservoir the rest of the way with water. Brew without using a filter and grounds or a coffee pod, until all of the water has been used (with a pod-based coffee maker, this may take a while). Discard the cleaning solution water that comes through. Then refill the water reservoir with fresh water and brew again without coffee until all of that water is gone, discarding it.
Fill the French press with half white vinegar and half warm water. Add 2 tablespoons of baking soda. Place the plunger and lid in place and move the plunger up and down a few times to agitate the mixture in the French press. Remove the plunger and use a soft bottle brush to further clean the canister. Unscrew all parts of the plunger and soak them in a solution of half vinegar and half warm water, then use the soft brush to gently clean them.
To prevent rust, let all pieces dry thoroughly before attempting to screw them back together again. Pour-through coffee makers, such as a Chemex, can be cleaned using the same method of vinegar, warm water, and baking soda, and the agitation can be done using a bottle brush. Small pour-through
coffee makers that sit on top of a cup can be hand-washed in the vinegar and warm-water solution to remove any buildup.
