What else can wear out grips?

Leaving clubs in the boot of the car on hot sunny days can dry out grips and leaving them in the garage during winter can also have a negative affect. Whenever possible, always keep your clubs indoors and make a habit of cleaning them after every round. Many golf bags have dividers for clubs so pushing and pulling the clubs in and out the bag can create wear. Take the clubs in and out the bag carefully and this will help to prolong the life of all your grips.
