so one of my white b/d had a stain that i decided to bleach. the stain was really hard to get out after spot cleaning, so i soaked the entire shirt in bleach (mistake) and now the entire shirt has turned to a faint yellow tint. after repeated washes the entire shirt is still a faint yellow. at least it is uniform. just wondering if there is a way to get it back to full white. the shirt is 95% cotton/5% elastine. i read that bleach can change the color of non cotton fabric so anyway to reverse/fix?
