The Case of the Stinky Coffeemaker

Got a resistant odor in your kitchen that you just can’t identify? Or locate the source? Hmmmm. When did you last de-grunge your coffeemaker?

Our good friends at tell me that coffeemakers need to be cleaned at least monthly to remove hard water deposits, leftover coffee oils that become rancid and other impurities. The oils in coffee collect, spoil and form bacteria when allowed to lurk inside that appliance.

This means I am about 10 years behind. Sure, I run a carafe of white vinegar through my coffeemaker from time to time (read: maybe once a year), but that’s about it. Whoops.

I’m learning that vinegar alone won’t do a good job of deeply disinfecting the appliance. But I’m not comfortable with pouring bleach into my coffeemaker, either. Nok-Out is the perfect solution because it is non-toxic and completely safe to use in the kitchen, around kids and pets, too.

This is how to do a proper cleaning, disinfecting and deodorizing with Nok-Out: Spray the coffeemaker inside, outside―and all over with Nok-Out. Allow to sit for up to 10 minutes. (You could use this time to disinfect the rest of your kitchen while Nok-Out is doing its magic on the coffeemaker. Have you looked deeply inside your refrigerator, lately? Yikes.)

Fill the reservoir of the coffeemaker with clean water plus two ounces (1/8 cup) of Nok-Out. Turn on the coffeemaker and allow it to go through a full cycle. Do NOT use the carafe to pour this into the reservoir. You may be re-introducing coffee oils and bacteria back into the coffeemaker. Don’t be surprised if the water that flushes through is tan or dark colored.

Unplug the machine. Using a paper or microfiber towel, start digging into the space where coffee grounds are placed. Beware of what you may find. Expect anything from grungy to shocking. Do the same on the coffee basket, if you don’t use filters.

Spray Nok-Out into the reservoir. Do not wipe, but rather allow to air dry. Nok-Out is non-toxic, hypoallergenic, tasteless and completely safe.

The next morning if your coffeemaker is anything but fresh and clean, give the contents and parts another round of Nok-Out.

Nothing removes odors like Nok-Out because it goes after the bacteria tcauseuses the odors, without perfumes or dyes.

    An eighth of a cup equals 1 ounce. So which should it be in the instructions? Two ounces (a quarter-cup) or one ounce (one-eighth cup)?

    Quite frankly, I have almost always used a coffeemaker such as Mr. Coffee or the like. There is no odor, there are no lurking smells, no lurking rancid oils, no bacteria build up. The coffee, itself, never actually touches anywhere but the filter and into the carafe. There are none in the carafe, either, as it gets washed with soap and water, occasionally a little bleach to remove stains from the carafe. The only possibility is mineral build up in the heating unit and little pipe that transmits the water to be heated. I can always tell when the water folks have added chemicals to the water system because it tastes like it in the coffee, as well. I am thinking this is really an overreaction to something else going on in the kitchen and it is not the coffeemaker. Keurig coffeemakers don’t even have contact with the coffee at all that I am aware of except at the puncture point when the water flows through those expensive little cups and into your own cup. So, I am really puzzled by this. But, yes, I agree it is time to clean the refrigerator.
