Sky marks are white marks left on the heads of golf clubs, most often on drivers. They are created when the top of the club head moves under the ball -- sometimes because the ball is teed too high. You can remove the marks with a few basic tools, but in some instances you may also need to use touch-up paint to give the club its shiny look.
Scrub the mark lightly with a paper towel and soapy water. If this does not work after a couple minutes, swap out the towel for a toothbrush and scrub in a circular motion.
Use a buffing compound if the soapy water does not work. Any buffing compound found at an auto shop will work.
Apply touch-up paint to the marks if water and buffer do not work. Let the paint dry.
Remove excess paint by gently rubbing it with 1,500-grit sandpaper and then smooth the area with 8,000-grit sandpaper.
Use metal polish to give the club a shiny new look.
