You just motivated me to rework on the Bleeker large flap bag. I think the same color as yours. Got it over a year ago, was quite dirty, after dunk still had some stubon stain marks here and there. I tried to cover those spots with paint & CPR mixture, but color didn't blend in well, so I put it away.
Just removed as much those paint as possible with acetone today, dunked again, those stains still stood out, was going to put into washing machine, but changed to hand wash in the sink, the leather soaked with water was almost as soft as fabric, and I hand washed it the same as if it indeed was fabric, lol. Surprisingly no damage done, and the stains lightened up now become bearable.
It is draining water right now.
