Nevr Dull
I use Nevr Dull, the terrific classic metal polish and protectant, easy to use. It does all the work while you gently rub it on. Generally available at most hardware and marine stores in a blue can. The can lasts for years......I suggest wearing latex or rubber gloves while using it, easier than washing the oxidation off your hands later. I use Nevr Dull on all my chrome, stainless and bronze fittings. Jim
