Ron is right. Grease seems to work it’s way out from the inside. Clean it dry solvent and then use golf grip tape. You can get this at your local pro shop or golf store. The downside of this is you will need to cut the grip off if you ever need to remove it.
Yes I did, cleaned up the handles and put them back on, they still were not perfect, I ordered a new set and no troubles since. I guess just like anything else they wear out!
It just happened to me this week end – It surprised me when I realized it was hanging half-way off! Never seen it before….. must be global warming….. haha
