My guess and this is only a guess, is that the Miele detergents are some form of the Trebon line that is listed on the web site and perhaps some of the Ottalin CL stuff since it is oxygen bleach and the detergent for whites contains this and perhaps some form of the COLOFIX line designed to retain dyes on textiles.
Miele says that their detergents are Zeolite free, which Persil does(at least my last box had it) contain, I think to soften the water. Could also be that the Miele detergent is nothing like this other stuff, but at least we know it is produced by a company that probably knows what it is doing.
You can order online from Miele USA from their miserably slow web site, but my local appliance store carries both Persil and Miele so I get it locally. The Miele stuff is slightly cheaper.
Ignore the package dosage recommendations. For me their recommendation is way TOO much for my needs. I use about the same amount of Miele as Persil so you will need to try it a few times to hit the right amount for your soil.
I tried adding hot water to the FS but when I returned the next week it was solidified again, which makes me think it is do the the cold temp in my basement. What would really help is if I had a good way to mix it. I added hot water shook it in a bottle but there were still clumps floating in the water. The thing is that this will go from the dispenser and into the last rinse ok and I have not seen any deposits on anything but I don't like clumps of FS being introduced into the tub.
I really do like their FS because it softens and smooths well and has a light undefinable scent which is why I am buying it as soon as it gets warm again.
