Fire Moose, I can see something but cannot tell what it is.
Are you convinced it's cleaning media because you analyzed it and therefore it cannot possibly be something else such a packaging debris or residue?
I'll call Winchester, ask them then post their response.
Yikes, Winchester's 1 hour wait for a phone contact made me email them. Hopefully, they'll respond soon.
