Has anyone used Durgol to descale their machine
I have a crossland cc1 single boiler machine. I got the Durgol free with my machine. The instruction said to put only 0.5L of water but it seem too less and also said that it doesnt have to let it rest and could flush it right away.

I used Durgol on my Silvia a few times as it aged. I think it works much better than Cleancaf (which is more a cleaner than a descaler, IMO.) It's powerful though, don't let it drip on any stainless surfaces or you WILL be polishing and buffing for days :)
That said, I imagine it's too soon to worry about descaling that machine. I did the Silvia once or twice a year with it. Unless you're using pretty hard water, I don't see a need to do it more than that. Especially not with your amount of usage.
Backflushing....yes. Descaling....no.
I can't remember what the water mixture ratio was though. I imagine it was more than that...but I don't remember for sure. The boiler certainly doesn't need much more than that. I did let it rest a little the one time since I had unwittingly used rather hard water for a brief time without realizing it (the vendor of the bottled water changed sources...) But you definitely don't want to leave that stuff in any longer than needed!

ya...read the package and it seem to be a lot powerful stuff
wow...you descale every yr....i thought i would be descaling every few months...i havent actually check my water for hardness so i think i should do that...let see if any fish store would have them....well now i have a softener in the tank...used it for a month now....
well it said one part durgol one part water...but the bottle is small so the actual total liquid is really little...not sure if it can pump that little in...just worry that ill burnt out the boiler if anything happen...didnt really say how long i should leave it in
It's nowhere near the acid used by repair shops when they do a boiler disassemble descaling & soak...but it's relatively powerful :)

It depends mostly on your water hardness and amount of usage. Back with the Silvia I was using bottled water that was relatively soft (at least in the beginning.) Since an SBDU is easy to descale it was simple enough. With the DB and HX machines, I'm not a fan of descaling (and my dealer, Chris's won't condone end user descaling at all, meaning under warranty I wouldn't do it anyway), so it'll be at least 2 years before I descale this one, as I have the extended warranty and wouldn't want to void it! That said I've been using excessively soft water, around 10-30 TDS out of the ZeroWater pitchers much of the time (technically too soft to be as tasty as possible), to avoid such issues for now. I could certainly go higher on the TDS and still be mostly ok, but for now, I'm good.
The CC1 is a "boiler and a half" but since the "half" is a thermoblock in the steam path and not a steam boiler, it should function like an SBDU in terms of descaling. Which is convenient. Steam boilers are what ruins it in HX/DB for descaling...it's hard to get the descaler out without removing some plumbing, which is most of what makes it a "warranty voiding" proposition with some dealers. (Actually in the case of the Duetto, the steam boiler is easier to get the detergent out of than the brew boiler....brew boiler requires removing plumbing and sucking the water out with a syringe....ick.)

Well if that's the instructions from Bill or the dealer, I'd go with it. Still, IMO with acids, you can never cause harm by over-diluting..... :)
