Discolored discolored sports shirts
It was just awful! I washed three neon sports shirts in the washing machine and all three - a neon yellow, a neon green, a neon red were discolored!
The dark blue stripes - probably from a washed jeans or the like - did not do my shirts well!
With the Hygenereiniger Denkmit (from the dm-drugstore) I got them as new! I feel like they shine even more than before!
24 hours (all three shirts together in a bowl!) And all stains are gone! Great.
