Subject: How to descale a coffee maker
 

I know I shouldn't be asking this here but I can't think of a better place.  My work just inherited a commercial brewer. We have VERY hard water here and I have to keep it working.  Can anybody tell me the proper way as well as what chemicals to use to clean and descale a commercial brewer?  It's a pour over (non plumbed) machine.

What machine is it?
I have found that for me, the easiest way to clean out a pour over brewer is to just take it apart. At least take the top off of the "boiler" or the place where the water is heated and give it a look see what is inside.

There are several commercial descaler products on the market, I think you can even buy coffee pot "cleaner" in a supermarket by MR COFFEE, if I remember correctly, it claims to descale.

You are right:  Descaling is a common problem here.

What I use is food-grade Citric Acid (powder).  I buy it from The Silk Road Spice Merchant in Calgary, look here.

Concentration for my Air-O-Swiss humidifier, for my Panasonic Hot-Pot and one or two other things (that boil) is 27 grams/liter and it works best above 140F.  The hot-pot boils it for around an hour and every bit of hardness is removed.

I like the idea that it is food-grade and if anything remains after rinsing it won't be harmful.  In cooking I believe it is used in Polish cabbage-soup and probably in Chinese hot-and-sour soup.  You will find it, in 30g containers, in some stores under the name 'Sour-Salt' but I needed to buy it in bulk (by the kilogram).

I hope this helps.

I don't understand that Jerry.. You're paying almost seven times! the price ($13.99 for 500 grams or 1.1 lbs) & ordering three Provinces away, that I pay for citric acid right here.

I've mentioned to you before (in other threads) where you can buy it at a place right in your 'backyard', & only $10.00 for 5 lbs.

It's a "Curtis CAFE0PP10A000 Low Profile Pour-Over Thermal Brewer".
Click Here

Descal I think would be the same thing right? I have been told from espresso mechanics that the liquid is better.  All coffee at work is expensed so I'm sure the cleaner is too so price isn't an issue.

Craig, you have answered similar posts ...similarly.  And once you promised to post the vendor of citric acid 'in my own back yard'.

But you never did ...?!

I did Jerry., they don't have a website. I posted the contact information.. I'll find two of the posts.

Not the latest, but what I found 1st: "Help Finding Citric Acid In Toronto?"

Latest: "Re: Now we know what GORT is (Behmor BraZen Brewer)"

Thanks, Craig.

I guess you posted it and I missed the posting.

I will contact them;  I am almost out of stock.

I am coming late to this discussion, but I just use white vinegar to descale my coffee makers.  We have extremely hard water here and a coffee maker can clog up in just a month or two.  I just fill the reservoir with vinegar and run the brew cycle and then run through two reservoirs full of plain water to clear the vinegar out.  Works like a dream.
