Cleaning ball
When you lift your ball from the putting green it may always be cleaned. When you lift your ball from anywhere else it may always be cleaned except when you lift it:
  • To see if it is cut or cracked - cleaning is not allowed.
  • To identify it - cleaning is allowed only as needed to identify it.
  • Because it interferes with play - cleaning is not allowed.
  • To see if it lies in condition where relief is allowed - cleaning is not allowed, unless you then take relief under a Rule.
If you clean your ball when not allowed under this Rule, you get one penalty stroke and must replace the ball if it was lifted.
