Clean grooves and grips can actually help...this one is a bit more obvious, but it’s no less important than anything else when preparing to play or on the course. Clean grips can help provide extra confidence during your swing that allows you to focus on hitting the proper shot. Think about it; will you swing the club confidently if you’re worried about your hands slipping on slick grips? Probably not. Also, clean grooves on your irons and wedges allow you to create maximum spin to help get the ball closer to the hole. Creating spin is all about creating more friction, and sharp groove edges absolutely help accomplish that better than grooves with dirt caked into them.
