Go to YouTube and look up patina method or patina champ. There’s also sprays but I don’t do that

Here’s my Speedy B from 2011 next the new Vachetta from my Bumbag.
(please note I still don’t carry this bag in heavy rain, but Vachetta over time develops its own weather proofing through the patina process)
And of course do your research before trying anything and use a light hand. This is just my experience I am not a pro and I am just sharing not suggesting or trying to teach.
Anything anyone tries on their bags is at their own risk but this has worked well for me.
