Cleaning a Coffee Pot with CLR

First thing in the morning after letting the dogs outside, I get a pot of coffee brewing. On this particular morning something was not right. My coffee maker was hissing, gurgling, and steaming at me. I had no idea what its problem was other than the fact that it was getting on in years and probably was going to bite the bullet soon. This five-year-old Cuisinart had seen better days but I hated the thought of putting out money on a new coffee maker right now, and wouldn't you know it; the darn things were on sale a week ago.

An hour after waiting for this pot of coffee to brew my impatient husband who wanted his coffee asked me when was the last time you cleaned it. It had been about three weeks since I did the vinegar flush and at that time not much of anything came out of the coffee maker. He then suggested that I try using the CLR that was under the sink.

Product that saved the day!

I highly recommend CLR for cleaning a coffee maker.

Is your coffee maker taking too long to brew coffee?

Calcium deposits from tap water can clog or block the small tubes and or pipes that are in the coffee pot. This is why it is important if you have hard water to clean the coffee maker and get rid of the calcium and scale build-up.

Normally vinegar will work quite well, however sometimes something stronger such a CLR may be needed.

Cleaning Coffee Pot with Vinegar

For each question, choose the best answer. The answer key is below.

  1. How often should you clean your coffee maker with vinegar?
    • Once a month.
    • Every six months.

Answer Key

  1. Once a month.

Scale Build-Up

The scale is accumulated layers of calcium and magnesium that stick to items such as; dishwashers, water heaters, faucets and coffee makers.

There are more minerals present in hard water than in soft water.

Over time the more build-up that occurs can cause your appliance to have to work harder and eventually stop working altogether.

When this happens in pipes, sometimes the pipes have to be replaced.

CLR for Other Household Cleaning Jobs

Use in toilet bowls, sinks, and humidifiers to remove lime scales.

Remove rust stains on brick, stucco, porcelain, chrome, and metals.

Removes calcium deposits, not only in coffee pots but from glass decanters, teapots, and glassware.

Use for cleaning dishwashers and washing machines

Whenever using any household or industrial cleaner please read and follow all instructions.

Procedure when using CLR in a coffee maker

  1. Mix 1 part CLR to 8 parts cold water.
  2. Pour this solution into the water reservoir.
  3. Insert a clean filter or if you are using a filter basket rinse it out well before turning the coffee pot on to brew.
  4. Run this solution through the coffee maker.
  5. Once it is done you should be able to see little bits of calcium left in the filter.
  6. If you've found quite a bit of calcium deposits you may want to run another mixture of water and CLR through the machine.
  7. Final steps: Rinse the basket filter or replace with a clean paper filter. Fill the coffee carafe with cold water (a full pot) and run it through the brew cycle. Repeat this step four times.

Have you used CLR and do you like it? Please rate accordingly


After cleaning the coffee maker with the CLR I'm happy to say that the coffee is hot and the Cuisinart is working like new.

Thanks Heidi, You too!

Heidi Thorne from Chicago Area on November 21, 2014:

Thanks for the reminder on this product! I've got to clean the scale on some of my glassware. Have a great day!

Susan Zutautas (author) from Ontario, Canada on November 21, 2014:

It's right there Audrey :)

Audrey Hunt from Pahrump NV on November 21, 2014:

I left a comment yesterday - not sure what happened to it. I have a keurig and this is how I clean it. Really enjoy this hub Susan. Sharing.

Susan Zutautas (author) from Ontario, Canada on November 20, 2014:

Audrey, I always try with vinegar several times and when that doesn't work now out comes the CLR :)

Audrey Hunt from Pahrump NV on November 19, 2014:

Thanks for the tips which will come in handy. I have a Keurig and vinegar does a great job on it.

Enjoy your day! Up, more and sharing.

Susan Zutautas (author) from Ontario, Canada on November 19, 2014:

Richard, Glad you were able to figure out what was wrong with your coffee maker. That's great when it works like brand new!

richardk on November 18, 2014:

We have the Cuisinart DCC-1200 coffee maker and had a major gurgling problem. Vinegar and CLR made no difference. Eventually discovered a packet filter inside a long plastic piece in the left rear, opposite the right rear water reservoir. Replaced the filter, cleaned out the coffee grounds that had encased it, and the coffee maker responded like it was brand new.

Abundant Old Soul from united states on April 26, 2013:

I will let you know. Thank you for allowing me to learn in new areas.

Abundant Old Soul from united states on April 25, 2013:

I have to try this. I always worked with vinegar! The Man's cleaner (ha)

Susan Zutautas (author) from Ontario, Canada on November 17, 2012:

Dzy, I wish those magic erasers would last longer than what they do. Hope this works for you.

Liz Elias from Oakley, CA on November 17, 2012:

Ah--thanks--I'll look into those. In fact, I may have one of those 'erasers' around somewhere....if I didn't use it all up the time I tripped with a pencil in my hand, making a long, dark mark on the wall paint... ;-)

Susan Zutautas (author) from Ontario, Canada on November 17, 2012:

Dzy, I wouldn't use this on your brushed stainless steel. CLR does however have a product called CLR Metal Clear. You may want to check into that. I just thought of something else that may work really well for you .... what about those Mr. Clean Magic Erasers.

Susan Zutautas (author) from Ontario, Canada on November 17, 2012:

GoodLady, I used to drink instant coffee at one time and if I had to I suppose I could go back to it ... Not that I'd ever want to to though :) Sure wish I lived with a clean freak :) Thanks for reading and always love your comments.

Liz Elias from Oakley, CA on November 16, 2012:

Hmmm...I wonder if CLR will work on NON-mineral stains, like some burned-on gunk around the stove burners, caused when the beans boiled over...

The stovetop is brushed stainless steel, and I daren't use anything abrasive like steel wool...(tried it once when it was new, and it did scratch the finish!) :-(

Penelope Hart from Rome, Italy on November 16, 2012:

Glad to say, since we don't have that CLR product here, that I don't need it. My companion of 27 years is a clean freak and gets the gunk out of everything! Loved this Hub. It's all these things that make the world go round. Well could we ever start the day without our coffeeeee - no way!

Sharon Smith from Northeast Ohio USA on November 10, 2012:

Cool, thanks. It would be the "pots" at work ;)

Susan Zutautas (author) from Ontario, Canada on November 10, 2012:

Sharon, As far as industrial coffee makers go CLR states the following on their site : Do not use CLR in coffee makers that hold water permanently. *CLR is not recommended for Gevalia coffee makers. *Do not use CLR in espresso machines. Just wanted to let you know. But on the pots themselves the CLR will work great.

Sharon Smith from Northeast Ohio USA on November 09, 2012:

I've never used CLR but have heard great things about it. At my current job, the coffee pots are used all day long and this would be a great thing to have on hand since some of them look bad and I am constantly scrubbing them. Thanks for the tips :)

Susan Zutautas (author) from Ontario, Canada on November 07, 2012:

barbergirl, I used vinegar for five years on the coffee maker and I guess it needed that extra something. The CLR worked great.

Susan Zutautas (author) from Ontario, Canada on November 07, 2012:

Lipnancy, I was quite surprised at how much calcium build up there was in the coffee maker.

Stacy Harris from Hemet, Ca on November 06, 2012:

I need to pick some of this up. Not that I need it for my coffee maker yet... it has still been running smooth but I haven't cleaned it in awhile and really should do that. However, or kitchen sink faucet has been getting sticky and getting hard to move. I keep forgetting to get some. Oh and interesting. I didn't know when you cleaned your coffee pot that you were supposed to use the filter. Good to know! :)

Nancy Yager from Hamburg, New York on November 06, 2012:

This is the one task I just think about doing. We have a terrible calcium problem here in western NY.

Susan Zutautas (author) from Ontario, Canada on November 02, 2012:

Hi duffsmom, The coffee maker is still going strong and I'll be using this method to clean it again soon. Nice to see you, and thanks.

P. Thorpe Christiansen from Pacific Northwest, USA on November 01, 2012:

I have heard of, own, but never used the CLR and it is time! We have extremely hard water and it leaves it's mark on everything. Thanks for the great hub and great tips Susan.

toknowinfo on October 23, 2012:

Great tips. Thanks for sharing your experience and great ideas.

Marisa Hammond Olivares from Texas on October 23, 2012:

CLR is great stuff. We have hard water in our area and it comes in especially handy in the bathroom. It can clean just about anything. Strong stuff though, I make sure I have my gloves on when I use it. Now you have me wondering about my coffee pot. I think it is long overdue for a good flush. Thanks for the tip.

By the way, I like fpherj48's tip about spraying the inside of the dishwasher with it.

Victoria Lynn from Arkansas, USA on October 22, 2012:

Great info! I think I actually have some of that stuff. Great to know how well it works. I'm going to do as Effer mentioned and try it in the dishwasher. Thanks for this hub, Susan!

Susan Zutautas (author) from Ontario, Canada on October 22, 2012:

Thanks everyone and I'm so glad to see that so many people love this product!

Chris Mills from Traverse City, MI on October 20, 2012:

This is a great idea and I like how you've added so many rinse steps after using CLR. I'm sure the Cuisnart company isn't going to like this a bit if their sales numbers drop. I use a french press so I won't need it there, but I think I will use it on the tea kettle. Thanks.

Claudia Porter on October 18, 2012:

I love CLR. I use it to clean the soap scum off our shower door and it works like magic. Great review! Voted up.

Judy Specht from California on October 17, 2012:

C.L.R. is the best. I would never thought to have used it in the coffee pot. The idea of putting the filter in while you clean, so you can see what crud comes out it is excellent.

I am in a cleaning mood and am on my way to clean the coffee pot.

b. Malin on October 17, 2012:

Hi Susan, CLR is FABLOUS! We use it a lot. Thanks for Sharing many more Wonderful uses for this product. Thanks for the Learning Experience.

Lela from Somewhere near the heart of Texas on October 17, 2012:

I love CLR! But I don't like the smell. Diluting it helps. Thanks!

Stephanie Marshall from Bend, Oregon on October 17, 2012:

Awesome information! I had not thought about using CLR to help clear deposits in the coffee maker. Makes sense. Rated up! Stephanie

Eiddwen from Wales on October 17, 2012:

Interesting and so very useful;thanks for this gem Susan.


Linda Rogers from Minnesota on October 17, 2012:

I love CLR Susan and learned about it's incredible benefits when I was a landlord of an apartment building. I'm glad to hear your husband got his coffee and your pot is good as new. This is a great little secret to share with your hub friends. I hit lots of buttons.

Susan Zutautas (author) from Ontario, Canada on October 17, 2012:

Thanks everyone for reading and for all the great comments.

Audrey Hunt from Pahrump NV on October 16, 2012:

Very glad to know about this product Susan. Good hub! Voted up and sharing.

Suzie from Carson City on October 16, 2012:

Susan...I am never without CLR or it's competitor Lime-away.....they both work well, but I prefer CLR.... I use it always to clean my entire bathrooms......full strength on a sponge for the tub and surround...and if you have glass shower doors, it's like magic. No scrubbing necessary.

Also, to keep your dishwasher not only running well and maintaining full water pressure...AND, I might add, the most sparkling dishes and glasses, I keep a spray bottle of CLR under the sink next to the dishwasher Soap.....I spray the inside of the door from side to side, top to bottom, each and every time I run a washer full of dishes!

You are correct, does wonders on many things!! I have a Bunn coffeemaker, which comes with it's own pliable spring-like rooter....for cleaning the calcium out.....& then I just run white vinegar through afterwards...Now...about my windows.........

Thank you for the Household cleaning tips from Susan!! ...UP+++.....

Ruchira from United States on October 16, 2012:

I agree CLR is wonderful agent to clean such scums around the house. I have used to clean my oven and my gas range with stuck up burns and no stinky fumes.

voted up as useful.

Kate McBride from Donegal Ireland on October 16, 2012:

That was a better solution than having to buy a new coffeemaker. It sounds like something easy to do and I will try it on my coffeemaker which is going slowly this past while probably for the same reason. Voted up and useful. Thanks for sharing this hub.

Liz Elias from Oakley, CA on October 16, 2012:

Excellent information. How funny--your Cuisinart is the twin of the one we just tossed in the e-waste pickup as it had stopped working on other levels (timer; leaking, etc.)

The replacement is a less expensive model, but I like it better, as it has a side-brew option for a single mug. Anyway, I'll remember to keep it cleaned out! Thanks for the reminder.

Voted up, interesting and useful.

Kelly Umphenour from St. Louis, MO on October 16, 2012:

Hmmm I may need some of this. I used some stuff in my dishwasher because I didn't think the glasses were looking very clean...wonder if it's the same chemical. Whatever it was I haven't been able to find it again so I will try this!

carol stanley from Arizona on October 16, 2012:

I used to use CLR all the time. Maybe it is time to think about using it again. Maybe in the bathtub. Great hub with lots of good information about the product.

Bill Holland from Olympia, WA on October 16, 2012:

Well that's helpful information! I'll let Bev know this; she uses the coffee pot every morning, and she will find this helpful. Good job Susan!
