A couple years ago I mixed up a batch of Ed's Red for the 4-H trap guns as they were on a tight budget. There was more than enough for both of us so I started using it on my guns with a lot of skepticism. Darned if it didn't work just fine on everything save for copper fouling. Pleasantly surprised.
+1 on Ed's Red. I'm a devotee of over 15 years' standing.
