Good job on editing and putting the quote in correctly, yay!

Just on the side - workflow burns calories.

But I do think it's a particular water content that stains, gets baked in - iron? Or your dishwasher doesn't rinse well, in general? I use Sun rinse, wonder if it's that. Brown/ginger stuff, tiny but not pale. But haven't had it for ages, try really clening the machine, de-grease it trough the hottest cycle? I wonder if you wash your dishes with something that corrodes during the wash and stains other stuff?

No… I said it's a Swiss model. The brand is Siemens and it's pretty new. I believe it's from 2017.

As mentioned before the machine is pretty new. Three years or less.

We can try with vinegar. We've been doing it now with the breast pumping items that they need to get boiled every night.

Hahahahaha no, isn't that… my wife is more the other way around. Usually she want to save as money as possible :P

What I believe is baked is the lime itself. Lime is white, but after a while it get brownish even at normal temp. if you don't clean your bathroom lime will build up and it will get a brownish color. I think heat just accelerate the reaction.

I soak everything with limescale on it in a sink of vinegar and water mix, overnight, then wash and dry.



And for mugs, which get stained with our rooibosch tea, I soak in mild bleach solution then put in dishwasher.

And the model or E-Nr. as it is a Siemens is ?? You do not really want help, do you?


Btw: Searching on the German speaking internet, two possible causes for discolored plastic can be found:
- Tomato sauce on plates (does not have to be in or on the plastic parts)
- Certain washing tabs which causes the stains and discoloration.

Maybe the rinse aid which was in the machine is not compatible with your detergent. Maybe the rinse aid which was in the machine and the one you filled in are not compatible. Maybe the salt setting is not correct for the water or detergent used (with some tabs the salt setting should be set to the minimum or even switched off).

What?

I never put plastic containers in the dishwasher, I always wash them in hot soapy water. Every so often I give them a soak in a solution of bicarbonate of soda to get rid of any stains and deodorise them. An elderly neighbour gave me this tip back in the mid 80s.

A few years ago a friend of mein had this problem. He had a black-brownish colour inside his maschine after the wash. We tried various things to solve this problem, washing with 45, washing with 70, setting the anti-calc system to clean at maximum, change the wash-tabs and rinse aid. I also made enquires by the manufacturer of the maschine and the detergent, after a few emails it became clear, this was not a "Kalk" problem. The colour was from the rubber seal between the door and the maschine. What could be taking the colour out of the rubber? To make a long story short, my friend was using a "ECO detergent" . The manufacturer of the detergent, use a sustitute for the "Phosphate" which is in most detergents. It was this substitute chemical which was not compatible with the rubber seals. We cleaned the maschine a few times with "Phosphate detergents" and the problem was away. I've been told this could also happen with plastics, the softening agents in the rubber and plastic are similar.

I got Denner's big gray box of tablets and it disappeared, when I am thinking about it..

Man… this is a really complicated country…

In btw… the model number is SX66P031CH/D3

We can test it…

WOW!! I owe you a beer… Where did you find it? or it of an equivalent model? I've been also looking for the oven's one and the ceramic glass… all of those are siemems.

Well, ASwissInTheUS is our resident Chief Finder of Useful Links on just about any topic! You'll see...

By the way… has any of you used durgol?

https://www.durgol.com/int/

My main problem now is with a humidifier… I don't now if this would be a better solution than vinegar.

As a cleaner? Depend on the vinegar. In French shops you can often find vinaigre de ménage at up to 14 degree strength (normal stuff is around 5 or 6) which is great for metal surfaces, but I wouldn't use it in coffee machines or the like, far too corrosive. Mind you, for really stubborn calc, particularly in toilets, the same French supermarkets sell quite strong hydrochloric acid, which works a treat.

So it all boils down (no pun intended) to what you need to use it for. A humidifier should be quite resistant, I'd have thought, and also safe, in that any residue isn't going into your food and drink, so the vinegar might be worth a try. I use it for the cats' water fountains, which are easy to rinse thoroughly, and it works very well indeed.

Hey!

Thanks a lot. Durgol worked well on the humidifier, in general. However, where the atomization happened there is a crust of hard (lime?). I say (lime?) because I really don't know if it's that. It's mostly dark and I was created by the use of the humidifier in Finland, where there is almost no lime on the water.

So… I really don't know if give a try to that strong vinegar or even the hydrochloric acid. Do you know if one can find it easily in Zürich?

Thanks!

I really wouldn't recommend the HCl on plastics - I only ever use it for heavy lime deposits on ceramic/enamel toilets, baths and sinks. And if your deposit isn't reacting to the Durcol then it's probably not limescale, so it wouldn't react to other acids either. If it's not plastic, and if it's reacting but just taking forever, then it may be worth a try. H&S bods would recommend wearing rubber gloves and eye protection when using it.

And TBH the only reason I'd use the strong vinegar rather than the specific limescale cleaners is because it's cheaper and (in France) easier to find. I use it regularly on coffee machine reservoirs and kettles, just a quick spray, leave it a couple of minutes, then rinse well, leaves them sparkling for each new set of guests.

No idea where you could find either in forn parts like Zuerich.

Thanks for the advice. I think it's reacting the Durgol, but it's taking forever. Before reading your post I was thinking that towards the end of the winter and before we put the humidifier back in the box for the summer I'm going to leave the Durgol a couple of days and see if that crust is finally gone or at least make it soft enough to scrub it.

If it's not lime, I really don't know what it could be. It's true that where we were located in Finland water was really soft and that crust was formed over the curse of two whole winters using the humidifier extensively (all day a long because the heating was quite strong).
