Outers Foul Out for brass? fouling?

The Outers Foul Out got the stubborn copper out of my ball gun barrel prior to switching to the new brass(?) jacketed Rem 230g FMJs.
Does anyone know if the same "Cop-Out" Outers solution will work to remove any brass(?) fouling (if it's stubborn like the copper)?
I haven't been able, yet, to get in contact with anyone at Outers.
Thanks, Russ

Outer's rep just called.
He said the Outer's Foul Out Cop-Out solution should work on the fouling from brass colored jackets as well it does on the copper fouling.
He said the Outer's Foul Out systems are no more. - Glad I have one and a good supply of Cop-Out and Lead-Out solution. -- I only use it a couple times a year - glad I have it when I need it. -- -  Russ
