Hello! I am a novice shoe repairman. While washing your Hermes Oasis sandals with saddle soap,
the soap bubbles and soap water got on the natural leather sole.
At first, I thought it would be okay if I dried it well, but the stain does not come off no matter how much I dry it.
How can I get it back to its original condition? The saddle soap is a Fiebings product.
