Discovered – 7 Amazing Ways How To Clean a Coffee Filter Basket

Your coffee maker could be killing you, so keep on reading how to clean a coffee filter basket and the coffee maker as well! It is if your morning cup of coffee is an issue of life and death, and you’ve got a filthy coffee maker. When was the last time you cleaned your coffee maker? Washing the pot is essential, but getting the inner components of a coffee maker clean is a job that shouldn’t be skipped. Did you even know that you were supposed to clean it? A clean coffee maker may be the difference between a good cup of coffee and a nasty cup of sludge.

Chances are you don’t wash your coffee maker as frequently as you should. In reality, 50% of those household machines contain yeast and mold, according to one survey. That makes it more germy than your average bathroom faucet handle. Yikes.

How To Clean a Coffee Filter Basket

Over a year ago, I wrote about using denture tablets to clean a coffee basket (such as a Mr. Coffee basket or a manual drip cone). And that really does work pretty well. However, I’ve now found a way that is faster, uses less water, and does a much better job. Additionally, it works well on removable Keurig filters and on permanent coffee filters (I’m still not crazy on the permanent filters — read here — but that does help with the build-up in case you use one). All these get some build-up from the coffee oils that simply does not come off with regular dishwashing.

So what is this better way? Spray it with a few Krud Kutter (read about it or watch it on Amazon) and then use a bent toothbrush to scrub a little (it takes about a minute to bend a toothbrush, see how to do it here). Krud Kutter is non-toxic and does not leave any taste or odor — just rinse well. It took no time whatsoever and no hard scrubbing; I use the bent toothbrush to get into the little nooks and crannies.

Using a toothbrush

For the record, after seeing how well this worked, I tried the exact same basic technique with a few kinds of dish soap and also with an Awesome degreaser. I wondered whether it only had a brush to wash with. This made a difference. Nope. None of these worked almost as well as Krud Kutter, though with no brush, I could not get the nooks and crannies clean even with the Krud Kutter.

I tried this first with my Melitta cone. Know earlier pictures as I did not expect it to be a revelation, but suffice to say that it has been tough to clean down in the base of the”V” shape. Here’s the following — not bad for a 10-year-old cone that has seen a great deal of use!

Here’s a before and after on the Mr. Coffee basket. Yes, the”before” is disgusting, and I’m embarrassed to show it, especially as it took about a minute to change it to the”after:”

I thought that cleaning with contraceptive pills made things much better, but Krud Kutter and a bent toothbrush take”easier and cleaner” to a whole new level.

To be sure that you don’t consume any of the germs or coliform bacteria this appliance has been proven to grow, we requested Carolyn Forte, director of the Good Housekeeping Institute Home Appliances & Cleaning Lab, the way to keep your machine clean and your coffee tasting great. It is essential to follow these three rules:

1. Wash removable components with dish soap after each use.

“This is important because it helps remove coffee, grinds, and oil that are left behind,” says Forte. “You can hand wash at the sink with warm and soapy water, but usually the pieces are dishwasher-safe. And don’t forget to wipe down the outside and the warming plate where spills can burn on.” She also recommends leaving the reservoir’s lid open use so that it can dry out completely after each use — germs love moisture!

2. Decalcify your machine every month with vinegar.

With time, hard water minerals can build up in your machine’s inner workings, and you may realize that your coffee takes longer to drip. To get things back in tip-top shape, you need to cleanse and decalcify the machine—Forte’s trick: good ole’ reliable white vinegar.

Fill the reservoir with equal parts water and vinegar, and put a paper filter into the machine’s empty basket. Position the pot in place, and “brew” the solution halfway. Switch off the machine and let it sit for 30 minutes. Then, turn the coffee maker back on, complete the brewing, and dump the full pot of water and vinegar. Rinse everything out by putting in a brand new paper filter and brewing a full cup of freshwater. Repeat once.

3. Make your carafe sparkle again with rice.

You should always wash your carafe after each use, but if it’s looking dingy over time, fill it with warm, sudsy water, and a little rice. Swirl the mixture to loosen any gunk. Use a clean sponge to remove debris and rinse thoroughly.

A clean coffee maker makes a huge difference in how your coffee tastes. Leftover coffee oils can collect within your coffee maker. Also, mineral deposits can form, especially in areas with hard water. These deposits are known as”scale.” There are two sorts of scale, limescale and mineral scale, and you do not want either one. Scale can affect the heating unit and the water flow of your coffee maker and reduce its efficiency. How quickly scale forms are dependent upon the quality of your drinking water. If you use bottled water to make your coffee, scale probably won’t form as fast, but you still need to think about gathered coffee oils. Better to play it safe and clean your coffee maker regularly.

Not a hard task to clean a coffee filter basket

Cleaning your coffee maker is not a hard task to accomplish, and in fact, it’s as easy as making coffee. All you have to do is pour a kettle of half vinegar and half water to the coffee maker’s water reservoir. White vinegar should be used. Steer clear of the red wine or apple cider vinegar varieties. Then just turn on the regular brew cycle. Your kitchen will probably have a pleasant salad smell while it’s brewing that you might even like. If you’re not a salad fan, though, just bear in mind that it is a small price to pay to get a good cup of coffee.

Now rinse the coffee maker out by using just water this time at the water reservoir and running the brew cycle. You may have to do this a few more times if you still smell the vinegar.

Another simple way to maintain the coffee maker clean would be to put a glass marble in the water chamber. All of the mineral deposits that would usually accumulate within the coffee maker will instead collect on the marble. Every once in a while, just remove the marble, wash it, and then put it back in the room. How much easier could that be?

The ideal solution would be to clean your coffee maker with vinegar while at the same time employing the marble method. Change the marble once weekly, and your coffee maker will be in great shape.

If you have an old coffee maker and you aren’t pleased with the flavor of its brew, why not try to clean it. A clean coffee maker will brew better-tasting coffee. Here you can read about the health benefits of coffee.

How to clean coffee filter machine

  • What You’ll Need
  • Water
  • White vinegar (enough to fill up half your carafe)
  • Hot soapy water
  • Sponge
  • Damp dish towel
  • Dry dish towel


  • Empty the carafe and grounds: Empty and rinse the carafe and ditch any coffee grounds left in the filter.
  • Make your cleaning solution: You’ll want one part water to one part vinegar.
  • Pour the solution into the water room: Fill the water room to its entire capability with equal parts white vinegar and water. I used the carafe to quantify equal parts of each.
  • Run a half brew cycle: Start a brew cycle. Midway through the brew cycle, turn off the coffee maker and let it sit for an hour.
  • Finish the brew cycle: After an hour, turn on the coffee maker and let the brew cycle complete.
  • Discard the vinegar-water solution and run a freshwater cycle: After the brew cycle has finished, pour out the vinegar-water solution and fill the water chamber with fresh water (no vinegar).
  • Run a whole new brew cycle only with the water. Repeat two more times, allowing your coffee maker to cool slightly between brews.
  • Wipe down your coffee maker: Wipe down the outside of your coffee maker, and wash the carafe and filter basket in warm, soapy water. Reassemble and make coffee that doesn’t taste like feet!
