Welcome to Your No-Sweat Guide to Spring Cleaning, a month-long series that puts the fun (yep, for real!) back into cleaning. We’re talking spruce-ups that take less than five minutes, why-didn’t-I-think-of-that hacks, and hands-off cleaning tasks that basically…do themselves—plus our trustiest tools and helpers. The goal: clean less, go outside more.


For most people, the coffee maker is a sacred appliance tasked with providing the day’s critical caffeine supply. And while the coffee maker gets a ton of use for this reason, it doesn’t actually receive as much care as it should. If you clean your coffee maker regularly, we stand corrected—but we’d be willing to bet you don’t. You’re not alone, though. Until we did our research, we weren’t maintaining our coffee makers properly, either. But once you know, you’ll never go back to your old ways.

According to an NSF International study, the reservoir of a coffee maker is the fifth germiest place in the home. Yeast and mold were found in half of the makers tested, which really shouldn’t come as a surprise. The warm, moist environment of most reservoirs is ideal for such microbes, as well as other germs and bacteria, to grow. We can all agree this is pretty off-putting, but it can also be harmful, especially to those with allergies and asthma.

On top of the yucky, potentially dangerous consequences of neglecting your coffee maker, failing to clean it can also negatively affect the functioning of the machine and the flavor of the coffee itself. (Nooooo!) A buildup of hard water minerals can result in clogging, while buildup of coffee oils left behind by brewed coffee can become rancid and cause even a fresh pot to taste bitter. These can both easily be avoided, however, by regularly removing the residue.

Coffee deposits are acidic, so baking soda more effectively removes them, and it will kill molds and deodorize. Other important thing; don't leave the machine sitting with water in the reservoir- pour it in right before brewing.”

And that’s why we’re here, to show you exactly how to properly maintain your coffee maker. With a commitment to a combination of a daily quick-clean and deeper monthly cleaning, you’ll be sipping cups of safe, delicious joe in perpetuity.

Your Daily Routine

Step 1: Accept that you must clean your coffee maker every single day.
Step 2: Dump out all your coffee grounds.
Step 3: Wash all the removable parts of your coffee maker with warm, soapy water. That means the lid, filter basket, and carafe should all get a once-over. A sponge is highly recommended.
Step 4: Once all the items are sparkling, either towel dry them or leave them out to air-dry.
Step 5: Wipe down the exterior of the coffee maker with a damp paper towel.
Step 6: Reassemble the coffee maker for tomorrow’s very necessary brew.

Your Monthly Deep Clean

Step 1: Force yourself to perform a deep clean, knowing your future self will thank you.
Step 2: Fill the reservoir with equal parts white distilled vinegar and water. If your maker is extra icky, you can increase the amount of vinegar. Vinegar has natural sanitizing properties that will dissolve mineral deposits, cut through grime, and overall deodorize.
Step 3: Place a filter into the machine's empty basket, position the carafe in place, and brew the solution halfway.
Step 4: Turn off the coffee maker and let it sit for 30 to 60 minutes.
Step 5: Turn the coffee maker back on and complete the brewing.
Step 6: Dump out the pot of vinegar water.
Step 7: Flush the vinegar scent out of the coffee maker by brewing a pot of fresh water.
Step 8: Brew a second pot of fresh water and feel happy that you don’t have to complete this process again for another month.

How often do you clean your coffee maker? Go on, you can tell us.

I have found that using Veggie wash (used to remove pesticides from vegetables and fruits) to wash the carafe and basket etc daily really helps remove the residue that often remains EVEN after cleaning with soap and hot water

The Moccamaster (maybe others?) retain a small amount of water in the system after brewing. When you come back from a trip or absence of a few days, run a reservoir of fresh water through the system before brewing that first new pot of coffee. The old retained water taints your coffee horribly! Best tip I ever got!

I guess you could say I need to wash ours (mine) more frequently. My husband uses an Italian expresso pot so that's his duty!

The vinegar for the carafe might be good or even fantastic but speaking from experience (never tried vinegar for that specific purpose although I love it for others especially descaling hardwater), the three magic ingredients are:

lemon
salt
and some water

along with some vigorous swirling.

That will take any coffee pot and remove any stains that might accrue over time. When I worked in restaurants, it was the be all, end all of coffee pot cleaning. I think we did it once a week as part of our maintenance chores.

It was fun and you could watch it clean as you swirled. Kind of zen too :)

Do you need to put a paper filter in basket if you have a permanent filter?

Every time used, we air dry ALL PARTS for at least 2hrs. included the charcoal filter. Totally disassembled. We do the vinegar brew also but not monthly.

I put all removable parts except the carafe into the dishwasher, and run thru the cycle with other dishes. The Ninja metal carafe is much more difficult to clean.
