I would recommend most user NOT use Renovateur on your burnished calf shoes UNLESS the desired result is to strip away the burnishing. My formerly heavily burnished walnut Ritledges are now simply walnut Rutledges after a single light coat.
As a cleaning agent for shell, or on black calf shoes, it does work very well.
But for the gentleman who is trying to alleviate the small stray burnishing mark, it should work nicely.
Yes, my point exactly. Reno removes burnishing. Especially if you apply it with a cloth or a brush. Using your fingers tends to affect burnishing less. But the simply fact of the matter is that the AE burnishing tends to come off no matter what you do. It's not a dye, its basically just a polish they add at the end. So best thing to do is learn how to burnish shoes yourself, so you can maintain (or even improve) on what comes stock from the factory.
OK, hopefully images will work this time. Before:
