I've always did the Bucket wash the parts deal with my Cap and Ball revolvers and many other Black powder guns! I know a fellow that swears by the dishwaser deal and I've seen some of his guns and they are clean? I did notice when he pulled them out of the washer, they has light rust on many parts and he had to go to oil very soon after out of that or they would streak rust badly? In my estination, it works, but is not a lot less effort than a Bucket wash if you do it right, with Hot soapy diswashing liquid? I swear by that method and It's kept my Cap and Ball and hawkins just fine! Hope this helps to some small degree? let us know what worked best for you?
