I've been asking a lot of questions today even though I am reluctant to ask for help. 
I'm wonder about this home brew bore cleaner known as "Ed's Red". (I think many are famliar with "Ed's Red".)
My question is:
What fouling will this solvent cure? Carbon only? Or copper as well? Leading possibly too?
Also, is it okay to use this on other parts? I.e.; bolt, receiver, piston, etc?

The link to the solvent concoction I'm talking about is here:
