Cleaning your grooves does more than just improve your spin and launch on clean shots. Let’s compare your grooves to the tread on your tires. On a beautiful and dry 80-degree day, the quality of your tread will matter a little, not too much. But on a cold and rainy day, you need those treads to be in good quality to make sure you aren’t slipping and sliding all over the roads. The grooves on your clubs are similar to this. Not only do they provide more friction on a stock shot from a clean lie. They make a big difference in the rough, in the rain, and when the conditions aren’t perfect. If you aren’t keeping your grooves clean, you’re hurting your game. It matters!
