Just putting my 2 cents in here..it's still easier in the long run to REMOVE the hardware.Additionally, you get rid of all the Verdigris that is ruining the leather. And Yeah, steel wooling the Brass takes time, but it's an excuse to listen to Movies, Podcasts,Music, Books- Or nothing.Sometimes just scrubbing something is a stress reliever.(of course I could be scrubbing my floors & the rest of my house.Nah) I never feel like my bags are completely rehabbed &clean unless I remove the turnlocks. Ah well, that's just me & my OCD CHEERS Y'all
