Yup......rookie question. My only other 1911 (a Springer RO) has G10 grips which are pretty much impervious to anything you can throw at them. Now that my beautiful new DW Guardian has made it's first range trip, it's time to clean her up. Per many other threads, I'll be using Aero-Kroil and WC Ultima-Lube II Oil for cleaning and lubing the Duty Finish gun. Will these products harm the cocobolo wood grips? Should I remove the grips every time I clean the gun? I've never had a problem with cleaners on my wood revolver grips; but then I use Ballistol on those guns.
