Soak means putting them in the bathtub with hot water. If you wash them in a machine when you first buy them it makes it very difficult to get much contrast in your fades. Which is fine if you're going for just a dark denim look and don't want ''sick fadez". And don't put them in the dryer unless you specifically want to shrink them.
I will handwash with warm water and hang dry then. and by the way, should I hang dry in shade or direct sunlight?
