Re: Removing stain from clothes
You are looking for an 'Entfärbungsmittel für Textilien.'
I last bought the stuff some years ago - back then one had to get it at the Apotheke. But I *think* I saw a product at the Coop not too long ago (maybe from Kr2?) - look in the laundry aisle.
I can't remember the brand name, sorry - but ask for an Entfärbungsmittel and the folks at the Apotheke will show you what's available.
So how did it work?
Colored sock in a white 95 degree wash: The whites didn't exactly go back to white, the best I could get with two tries with the Entfärbungsmittel was more a light blue (black sock). As these were dish towels I could live with that.
Don't forget to clean the washing machine and run at least 1 empty 95 degree wash after use.
