Where are you getting it? All over? I only see this on areas of the shirt that have been over soaked due to the hem or edge of the shirt touching the fluid back up in the trench that drains at that back of my viper one. I also don't even think those areas are getting pressed most of the time so the crystallization only occurs after the shirt sits and that dries on the shirt by air. Are you pressing it with Kraft paper? How long?
