So I've had my Reo for about a year now. Past couple months I've noticed that whenever I reapply noalox after giving my Reo a cleaning there has been a crust forming on the firing pin from previous applications. I've tried picking it off but it's like it's fused with the metal. Maybe I need to apply more pressure or give my Reo a soak in something but I don't want to damage anything. Any advice?
