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?

| | Re: Lime problem with light plastics on dishwasher | Quote: | |  | | | Sorry, one more thing...
You said that your machine is a Swiss brand and that the manual is only in German. Is the brand Zug, by chance? If so, Zug does also have all of their manuals available for free download online, in English, as .pdf files. | | | | | No… I said it's a Swiss model. The brand is Siemens and it's pretty new. I believe it's from 2017. | Quote: | |  | | | Well, there's a simple way to test if the discoloration on plastics is limescale. Get some vinegar, a piece of cloth and scrub. If the stain is gone, it's limescale, if not it's color from the food. We have at home some plastic items perennially stained with tomato sauce, very common.
What pancakes mention is true. The machine can be 10 years old or more and not cleaned that frequently. Try using a cleaning product a couple times and see if the outcome improves.
PS. a stupid joke....could all this be a indirect way your partner tells you to buy new kitchen items? Sometimes the truth is right in front of our eyes, but we nerds start thinking about water carbonate hardness instead of the simplest answer. | | | | | 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 | Quote: | |  | | | Good job on editing and putting the quote in correctly, yay!

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.

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. https://www.chefkoch.de/forum/2,27,3...chine-rot.html https://www.stern.de/digital/technik...t-9113212.html
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).

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.
