Hey, I just was given an old hunter style bridle today (probably from the 50s) and I cleaned it all up and then figured out that I can't take the bit off of it to change it out. There are no buckles where the bit attaches to the cheek pieces, instead it's sewn. That means I can't switch out the bit. I don't mind the bit that's on it. It's an old brass/copper colored o ring snaffle. The problem is that it's kinda gross looking. It is tinted green and looks grimy. It won't come off in soap and water.
Is there a product that will make it shine? Any advice?
