Good Morning. Sorry for the delayed response. Honestly, after dunking, drying, along with some reshaping, not too much. I slathered, daily, for over a week, CPR on this bag. On some of the really dry spots, I used Chamberlins leather balm, I tested it on the strap first because it showed the most signs of age and wear, and if it turned dark, so be it. When I saw that the leather balm didn't ruin the strap, I sparingly used a tiny bit on the front flap. I am pleased with this transformation, as this bag was really rough!You did an amazing job on this bag! I saw the 'before' pics and somewhat cringed, tbh. Would you mind sharing your steps, please? Beyond the dunking/washing.
