How do i clean a solid Gold spoon!

Hi Harvy. If your spoon was solid gold it would not need cleaning. Gold unlike any other metals does not tarnish or get corroded ever. Even after a thousand years of being in the dirt the gold item will still look like it was the day it was lost/buried. Your spoon is either gold plated with some of the plating worn off, or it's not gold. Can you post a picture of it? Matt

I found two gold rings, that were the same way. They had been in the ground over a hundred years, and the minerals in the ground had turned their outsides brown, I don't know why. I took them to a jeweler to be cleaned and he confirmed that they were indeed gold. 8)

9-10 K gold will tarnish. I used a dremel, polishing wheel and polish to clean up a few 9K rings. HH, Mike

Everything oxidizes, even gold. Under normal circumstances, the oxidization process is so slow on precious metals, gold, silver, platinum, that it appears to not corrode or tarnish, even though in reality it is slowly doing it. Under abnormal circumstances, the process can be sped up alot. All anyone has to do is what the National Geographic special about the recovery of the gold coins on the Republic (I think thats the one) and watch how ugly the coins that were found were, and then how carefully they were cleaned. The surrounding environment in which the metal is subjected too, certainly plays a large part in how quickly the metal oxidizes.

I am affraid I will have to disagree.

Gold does not corrode, and it conducts electricity very well. Gold can contain small amounts of other minerals that change its color. Copper will make it darker yellow, while gold with silver can almost make it white. Pure gold is called 24 karat gold. Because it is a soft mineral it is usually mixed with other metals such as copper, nickel and silver.
(From the ask Jeeves site)


It is the other metals present that corrode or tarnish. I don't know the Karat rating for US minted gold coins, but I doubt that it is over 14K.

Enloe Post a Pic of this before you clean it and then after. Also tell us what Karat it is. I would not take a dremel to it untill any exterior impurities are gone. soaking in a mild acidic solution like water and lemon will eat most surface problems quickly. Also a good soaking over night in some reg detergent and water will do too. If its solid above 10k you wont hurt anything. good luck and lets see the pic.

I would clean it by putting it in a jar large enough to cover it with white vinegar (5%) for a minute or two. Afterwards, bring it out, dripping wet, and cover it with baking soda. Rub it with your fingers until the baking soda takes the tarnish off, rinse under tapwater, and dry. If it is gold it should clean up nicely. Plating (if any) will come off as you rub it. You might look at the edges with a magnifier to make sure it isn't plated first.

"I don't know the Karat rating for US minted gold coins, but I doubt that it is over 14K."

Actually, U.S. gold coins have always been 90% gold, 10% copper. This works out to be about 21.6 Karat.

gold can tarnish..
there have been instances in out local chuch where certain gold relics had to be cleaned and polished cause they were changing color due to being in contact with other metals.

a jewler can confirm this..

This coin was struck sometime between 364 and 378 AD. It is a solid gold "Solidus" of emperor Valens. As can be seen, this coin looks the same as it did when it was struck over 1500 years ago. If I were to throw it out in the yard today and some archaeologist were to find it 10,000 years from now, it would look the same (assuming it wouldn't get damaged or destroyed by some mechanical force).
