I have used cleaning solvents that are frequently mentioned on the site with good results. I recently was working on an old A3Springfield that had years of crud in the barrel and proved to be stubborn. A friend of mine said to try the foam cleaner "Wipe Out". I did, and within a brief period the barrel was literally spotless. Carbon and copper were completely gone in a matter of minutes! Somewhat messy, and sticky feeling, it worked better that anything I have ever used. Any experiences with this product, especially using it with high grade barrels. This stuff seems too good to be true.

My rifle builder and his dad swear by the stuff. I have not heard of any issues in using it. He has a bore scope, but I didn't ask if had noticed any problems. The theory is there, good cleaning with less rod strokes. Wipe out is the cleaner he recommended for the Kreiger barrel he installed on my action.
