    I use 1/2 white vinegar and 1/2 water and run it through with a filter in it. It's helped, but I don't have extremely hard water here in Colorado.

      We have very hard water, great for showers, but he'll on coffee pots, etc.. I will probably start making coffee with distilled water.

    Citric acid. I use it to clean my jug out! Works instantly when it's added to boiling water!

    Should be able to purchase it from your supermarket.... It'll be around with the baking stuff like baking soda and powder. I'm in NZ and it's not cheap for a small jar here... But can get it at like bin inn stores... I guess you'd call them bulk stores where you take your own jars to fill or fill a bag with as much as you need! Our water here is hard it's terrible on jugs and showers washing machines anything that runs water through it! Best of luck! :)

    Just give it a full strength vinegar and fill her up and empty it 1 cup at a time you might have to repeat a few times so dont throw away the vinegar just reuse it, yes use the same vinegar .When all is done fill clean water and repeat until your water has no vinegar smell.Do this once a month works well for me. Good tip don't use tap water get yourself a Breta filter.

    I live in Hodgenville KY and we have a well. I have to clean my coffee pot out once a week or it does not work. I fill the while thing up with straight vinegar and let it run through until empty. Rinse it out several times by running hot water through a cycle. (I do it until I can't smell the vinegar anymore). Works like a charm. When it's done, wipe the inside down with a damp cloth and all the mineral buildup will come right off.

    Yes, I think lemon juice or vinegar would work fine. It's cheap and you probably already have it. The vinegar also can be reused, I would assume, although I probably would not reuse the lemon juice in my tea.

    Would CLR be harmful?

    Vinegar with water. Let it sit. If it's the maker, run the vinegar water mixture thru your machine. Let is sit in the pot for 30 minutes or so.

    Pure white vinegar. We run the vinegar through twice then run clean water through twice.

    Ours had completely quit working. Poured warm vinegar in the reservoir. Pushed plunger at the bottom several times. Put it back on the Keuric and let vinegar run thru the pot. Then recycled it one more time. Let it sit for 24 hours. Flushed with clean water several times. Worked like a charm. Good luck

    Thank you all for the inspo! Our water in NM is hard, hard, hard. Definitely will try the vinegar/water mix.
