Cleaning your grooves after every shot either on the course or practice is helpful. If you want consistent spin with the golf ball with our wedges then we need to clean our grooves, When watching the GOLF CHANNEL when watching players on the range for warm up you see the caddy with a wet towel cleaning the clubs of the player. When I practice my short game from bunkers to pitching the ball I wipe off the SAND or Dirt. Keep it clean
