we had for a long time the problem is that dark laundry quite violently stinks to me after some time among the poor, even though it has just been freshly washed. However, only the dark laundry, and - before all blaspheme now - yes, I shower regularly and wearing t-shirts and shirts usually a time before they migrate back to the laundry. Our washing machine, a 2-year-old Bosch Logixx 8 and smells totally fresh, even if you put your head in the drum. And we'll throw every now and then to the hot wash. The dark wash is still stunk. Well, the bleach has not saved all laundry items (some very old have stunk relatively quickly and have long been disposed of), but actually worked amazingly well! Almost all garments were used again and smelled nice and fresh, without stink artificially softener. Why this is true as a bleaching agent, however, I do not know, the laundry was not discolored and remained recognizable as dark as before.
