If the nickel on your phonograph parts or your faucets is just basically dull <hint hint> the nickel is still there. And if the nickel is STILL there . . . Eric mentioned that there is no way to make it bright again. Perhaps not using a hand technique, but I do it all the time with a cotton buffing wheel and relatively fine polishing compounds like jeweler's rouge. The blackish specks won't completely go away if they are present (they are formed because of ferrous metal content in the nickel plate and they actually leave pits as the metal oxidizes) but with care, dull nickel plating is actually quite easy to polish to a bright shine. (I have some nickel plated fixtures in my bathrooms that are from the 1920s. It was a bit of work to get 80 years worth of mineral deposits off of them from hard well water, but once I did, they polish up like new - well, almost - sorta).Tinkerbell wrote:
Yes, kind of like my vintage nickel bathroom faucets! I spent hours trying to shine them up, but they're a lost cause...
As for using steel wool to try to make dull nickel bright again? I caution against it because the steel wool has no lubricant and even though it is very fine (#0000) steel is very hard and the risk of scratching, even if at very low levels, is significant. Wear is wear is wear, so minimize it. Nevr-Dull works well because it is a clump of natural cotton in a solvent that also acts as a lubricant. Like Eric said, it takes some elbow grease, but it is pretty safe to use. The cotton in Nevr-Dull is actually pretty coarse but because it is so soft it is not capable of polishing out the dull oxidize that makes nickel look bland. I often use rottenstone and liquid paraffin on a soft cotton rag. Even that won't get rid of very dull nickel. But a buffing wheel and some jeweler's rouge is like magic. Hey, you sound like a person who could make use of a spinning whizzing motor driven tool! Buy one!
Any time that you can use materials and compounds that are softer than the surfaces you are trying to clean or polish, you help to preserve the beauty of an original finish that will endure for many generations to come. I always like to think ahead 90 years to the next owner and try to put myself in his or her place. Only a very few machines of the past have received such love.
