Wipe your bowling ball often with a microfiber towel while you are bowling to remove lane oil and rubber marks.
Place adhesive tape over the thumb and finger holes to prevent liquid from getting into them.
Apply a small amount of liquid ball cleaner to another microfiber towel and clean the entire surface if the ball. Wipe the surface of the ball with another microfiber towel -- if any dirt comes off, clean the ball again.
Apply a small amount of bowling ball polish to a hand polishing pad. Apply polish liberally until the surface of the ball is covered. Allow the polish to sit on the ball's surface for a few minutes before wiping clean with a microfiber towel.
Place your ball in a bowling ball buffer/carrier and spin the ball back and forth several times to add even more shine.
