Greetings ruger357; There is a product called
"Simichrome" sold at your local K-Mart that
works pretty darn well, in cleaning up firearms. This product is a paste, pink in color, and comes in a tube. It is very good
for cleaning up nickel and stainless handguns. Sorry, but I forget the cost; as I
haven't bought any in quite a few years.

PS: It can probably be found in the automotive accessories area of K-Mart?
