On a green, I marked my ball, lifted it, and wiped the dirt off on the green beside my marker.
Was then called a penalty for testing the rub of the green ( which I wasn't trying to do).
I thought legitimate ball cleaning was ok?
Q.May a player clean his ball by rubbing it on the putting green?
A.Yes, provided the act is not for the purpose of testing the surface of the putting green. It is recommended that a ball be cleaned in other ways to eliminate any question as to the player's intentions.
Quite true, but there's a difference between topics which are matters of opinion and ones where there is a request for facts.
Not that people can't get the answers themselves with a few keystrokes.
This is an intent based penalty. As explained if you are doing it to clean the ball it's fine. If your also doing it to check out the grain, it's a penalty. If I'm in a tournament I would avoid doing this. Playing with my buddies, I'd do it and say "get over it, my ball is dirty".
BTW, you can also scratch the green with a tee to mark the position of the ball. The same caveats apply, plus the green superintendent might not be happy..
