The reason I bought my S&W .44 mag in stainless (Mod. 629-4) was to avoid endless cleaning. I scrub the barrel interior and cylinder face with Hoppe's No.9 using brass brushes only to the point of removing powder residue. Then I give it a shot of brake cleaner to remove the Hoppe's, relube the works, coat the barrel interior with Danzac and then wipe down with a flannel treated with Break Free CLP and Marvel Mystery Oil. While the Danzac was sold with the idea of increasing bullet velocity by reducing friction during it's pass through the barrel, this was found to be insignificant in handguns. On the other hand, it pays huge dividends in reducing leading/coppering. Huge. My cleaning time was reduced to a quarter of what I had to go through in the past. The MMO was added to my CLP treated rag after I saw how it kept my tablesaw from rusting over the winter back when my garage was my woodshop. Besides, it smells nice.
