Back in the early 80's I bought a used Bulldog .44 Special by Charter Arms. It has always been one of my favorite revolvers. Recently, I gave it to my daughter for personal protection. It is accurate and reasonably comfortable to shoot. She tried it and liked it. But as luck would have it, I wanted my Bulldog back! So I bought her one of these: http://charterfirearms.com/products/Charter_Undercover_53830.asp in the standard 38 Pink Lady edition. I showed it to her and she agreed to the return swap. So I told her I would take it home to clean it and then give it to her. Unfortunately, I've never owned a colored anodized aluminum steel frame before. The instructions say 1. no acids or caustics, 2. no chlorinated solvents, no hard rubbing with coarse abrasives. Anodize is considered an amphoteric coating and will be attacked by solutions of high alkaline or acidic nature. One recommended technique is to used an abrasive cleaning sponge with mild dish soap. Maybe drop the frame and cylinder (minus to rubber grip) into a pan of warm water and soap to soak for awhile and then swab and brush the bore and cylinder too. Am I on the right track here from people with experience on these materials. All of my experience over the years has been with blued guns. Also, I've used Hoppes Elite before and seem to remember it being a soapy watery cleaner. It also seemed pretty gentle. Would that work well? Anyways, any help from experience on this matter would be appreciated. Thanks.
