Anyone use Miele laundry detergents in your W3038 or similar?

If so which one?

It looks like there are so many choices on their website -- capsules, liquid, powder.

I am tempted to give the sensitive powder a try since they advertise it as working well in cold water.

I have been using Sonett liquid detergent for years, but find it doesn't rinse out very well even with their laundry rinse product being used in conjunction with the detergent. I suspect it has to do with the temperature of the rinses (cold) since the detergent is designed to work at higher temperatures (30C/86F and above).
