Thread: Anyone else use Bore Techs 'Eliminator', esp in Stainless firearms?

I'd like to hear feedback re this product. It certainly does remove a heap of copper as per the rags coming out vivid blue without the gagging ammonia fumes - however.... if left on the surface of said stainless firearm, as per the can-do guide, it seems to turn a lovely brown, leaving patches of brown all through the breech etc... freaked when I saw this...! Doesnt move easy either.... End up pulling a patch of Inox through to remove the Bore tech.....
