Can be used on stainless and carbon steel, brass, gold, silver, chrome, copper, and many other hard surfaces.Made in USA.
I use it to clean all of our brass at church. I have tried everything on the market and it is the best. I initially found it at a flea market and was skeptical of all they promised but bought one tube and after trying it wished I had bought more and then I found it on your web site.
