How do I remove grass stains from a white dress shirt?
A little more information on the type of dress shirt and fiber types would have been helpful. First, check the care label and eliminate any items that include wool, silk, mohair, spandex, and leather. For all other types of fabrics, begin by presoaking the item in cool water using a good liquid laundry detergent that contains enzymes—check the ingredient list to be sure. Allow the shirt to soak for at least 30 minutes to help break up the stain. Then, since your shirt is white, apply Clorox® Bleach Pen Gel directly to the stain. Use the soft scrubber tip to gently rub a little gel into the stain, and the wash immediately in warm water with detergent and ¾ cup Clorox® Regular Bleach2. Air dry the shirt, and check for success. If any stain remains, you can always repeat the treatment, and your chances of eventual success go way up if you keep the item out of a hot dryer (and prevent the stain from being heat-set). Hopefully this is helpful, and thanks for writing.
