Okay I could use some advice. For six months now after I use the apartment washer my darks come out with white chalky spots all over them. I thought it was the old washer but it was replaced a month ago. Its really bad with sweat pants, cotton shirts. I only mix red, purple,brown and blacks. Can a laundry detergent be that bad to make a mess? I use Purex, typical dark blue color liquid detergent that does not seem to give my sensitive skin issues. Never even thought it could be detergent until now that I am nearly out of options. How that can make something white and chalky I dont get it? No one else in the building is complaining, otherwise I would swear I am washing right after a construction worker. Completely baffled.
