Yes Dellers Darkner is only for copper, it is also supposed to work on bronze though I've not tried that. It doesn't work on silver, it is a sulphur based paste as I recall, not a big fan of it, bet it does do it's thing on ugly cleaned copper. I heard it is no longer made, though still available on eBay/Amazon/etc. I no longer see it listed at Wizard, it was made by Harco.
A little history on Harco - https://caselaw.findlaw.com/ct-cour...1464129.html Not a happy ending at all. I see one guy selling the Dellers on ebay at $18.00 tube, as I recall it was MSRP around $3 or $4 per tube - (Not really a tube), but a small little hard plastic container. The stuff stinks like sulphur and has the consistency of vaseline. Probably was a petroleum base they mixed the sulphur powder into.
