Playing golf is fun and interesting (some of you read this as frustrating and cruel), if it wasn’t you wouldn’t be here… yet it can be pretty tricky and daunting at the same time. Dirty golf clubs can add to this difficulty and affect your performance in the game. If the grooves of your club are filled with dirt, then you wouldn’t be able to spin the ball effectively. (You may think “Hey, I’m not good enough to spin the ball yet”, but that’s not what I mean here. The grooves on a club will cause spin that helps to lift the ball as it flies through the air.) The position of club at the time of impact might not be affected by this; however your ball flight would definitely have to bear the toll of your dirty golf clubs.
