As an estate jewelry dealer and silver I was hoping this would be the answer to my prayers as I am unable to find the best metal polish on the planet, E. T. Mish's silver cream, used in the White House for years. It did make my stainless steel sink look a little better but I feel Wrights does a better job on silver.I tried it on a mixed metal Taxco collar hoping it would get good results but it didn't do much. I wanted to return it but no returns once opened..... how do you know if you like the results without trying it?? This was a pretty expensive experiment that didn't pan out...for $45 there are better and less expensive choices out there.
