Persil does work the best as well asn the SA-8
That has been my expierience. Even at the lower temps, which I as well as everyone has tried. Trial and error. Even at 140(hot) it worked.Sometimes, even with a good detergent, you should pre-treat. I washed a load on sanitize,granted it was a big load of white sheets and towels, and one of my favorate shirts. When the stain did not come out of my shirt, I put pre treater on it, and presto! My favorate 12 year old shirt is totally white again. I have found that some things get whiter everytime it is washed. It nay take a few times; depending on how many times it is washed and dried. When I first bought my Miele, it was time to see what it could do.
