I notice that Battara suggests "Sunshine Cloth". I suspect this is similar to the cloth I sent you, so try that with a toothbrush to get into the filigree. At least the toothbrush does not have metal bristles. If you look at the filigree of that Dharia I posted recently you will see the results using this method. There was originally quite a bit of black tarnish in the recesses.
