Hello chuck ,
chrome plated parts of any kind when in poor shape need to be replated.
also with nickle plate.nickle plate is done when chrome plating as the nickle is put on before the chrome.years ago a good chrome job included copper ,still
done in some places ,not Ca .They just do the nickle plate followed by the chrome plate.The KEY is to get a reputable plater even if it has to be sent out of state to get a good job.How do you know if you get a good job?
by how the luster is ,depth of shine ,clean shiny ,but it still can be a poor job.My experience is that its a gamble with chrome ,period .many years ago
before the EPA had to crack down on the caustic chemicals ,as smelting
copper gives off toxic fumes ,you could get a good chrome job.nickle plate
probably will get a good job .It does depend on how much time the part is left in the nickle bath ,same as the chrome bath.if the shop goes cheap on
you ,you don't get enough plating on your parts.Go to a highly reputable shop
and hope for the best.also if plating the stove top ,the flame and heat cause chrome to change color at the burner area ,known as bluing ,like chrome
motorcycle exhaust pipes ,so no way to stop that except to use a foil burner
protector under the burner rings,that might help a little .I have had alot of stuff plated and I will have more done ,but its lifespan is limited.
