Good product for cleaning nickle plated chrome

I believe that he is refering to the chrome plating process of applying chrome onto a nickle plating which is first applied to the surface of the object .
At least that is the way it was done in the automotive world for bumpers , wheels etc. A really good job would consist of multiple layers of the nickle .

Simichrome uses jeweler's rouge as the "abrasive" (which is why it's pink) It's also the only polish I know that won't turn aluminum black (which is why it's the favorite of bicyclists and motorcyclists.) Khun Rikon is a new one to me ;-)

Typically[sp] the chrome process starts with a few thousandths[.003-.007]of copper,then a couple thou[.002-.003] of nickel,then .001-.002 thou of chrome.It varies from shop to shop.Browns Plating out of Kentucky is probably the best known to us bikers.....so you are probably right Mark.I did not know of the jeweler rouge angle in the Simichrome N.,thanks....and yes,it works good on soft metals like aluminum also....I dont know anything about acids anymore.....goog luck,Bob
