Any update on these GD plate coats? Did a little searching online but didn't find anything.

I tried searching for a solution already posted but I didn't find anything directly related. My NB plate shoes are about 2 years old. When I go to clean and shine them up, I noticed that the small grooves in the "leather" seem to be filled with a whitish colored substance. I've use various means of shining them in the past (I know.....). Does anyone have any idea how to remove that? I placed one of mine next to my partner's last week and mine had a significantly lighter color. Will saddle soap remove it? And then black polish over it? I need some help! Thanks!
