    Thanks Louise.  I'd never used this mix, but it makes sense, upon
    reflection, which I didn't engage in before my first reply post to
    this thread.  I do wonder, though, whether it's all that effective on
    sterling silver, where oxides can penetrate the surface a bit.  Or
    doesn't that seem to make a difference?
