I have noticed, after running five razors over my .5 diamond pasted flatbed leather hone, that it's pretty dark (I'd imagine there are filiments of steel in it). Should I just leave it like this for another two or three months before I use it again? Or should I clean it? If so, with what and how do I leave it for packaging? Do we just not worry about the color of leather turning? If so, How do I tell when to clean and re-paste?

Thanks,
Chris
