>>>As the pic shows in fact it does make it through. The process used a saturation with the oil and heat to help penetrate the soiled leather. There is one corner that is somewhat light so my hope is that it can be revived.

You will find that the suede side has coarse fiber then the finer nubuck side.

Thus removing from the suede side is easier and not worry about surface distortion if you do it from the nubuck side - make sense with this practical point?
