I've heard of people doing this.... my dressage bridle just really needs some major moistorizing before this season!
I've never ever soaked leather unattended in oil (I have Neatsfoot oil) and I can't afford another *nice* bridle, so maybe I'm being a little paranoid.
Anyone else do this? How long should I soak it? Will the hardware rust? Any tips or precautions about doing this?
