I wear a shirt, I wash it on cold, I dry it, I pull it out nice and clean, and then when I put it on it has white streaks up and down the left and right of the botton half of the shirt. It only happens to sort of dark clothes (black, navy, dark red, sage) and only to t-shirts. I am so sick of washing clothes twice.
