This is a handy and maybe unexpected tip, but Coke does indeed clean gold. You can dip your gold in a small bowl of Coke and make sure that it is completely covered. Leave the gold plated jewelry in the solution for 10 minutes and then rub with a soft cloth and rinse.
Dip the jewelry in Coke and leave it for one hour. Heavily tarnished pieces can be left for longer, but not longer than three hours. Scrub with a soft bristles toothbrush if needed.
Can I use Coca-Cola to clean fine jewelry? You can use Coca-Cola to clean fine jewelry as long as you don't overdo it. Scrub very gently as higher gold karats scratch more easily. It's best to clean expensive jewelry one at a time to prevent damage from accidental bumps.
Does Coke Clean Gold? This is a handy and maybe unexpected tip, but Coke does indeed clean gold. You can dip your gold in a small bowl of Coke and make sure that it is completely covered. Leave the gold plated jewelry in the solution for 10 minutes and then rub with a soft cloth and rinse.
If you don't have any chemical cleaner, you can use Coca-Cola, or Coke, as a simple cleaning substitute for sterling or plated silver. The acid in Coke works to cut through any grime or rust on the silver's surface. Once you soak the silver in cola, you can have a piece that looks good and new!
For example, gold jewelry can be scratched by other pieces of harder metal, such as silver or platinum. Additionally, gold can be damaged by exposure to air and moisture, which can cause it to tarnish or corrode. Another element that can damage gold is sulfur, commonly found in the air and soil.
Chlorine is gold's worst enemy: with repeated exposure, chlorine will weaken your gold jewelry's structure and eventually lead to it breaking. Make sure to take your jewelry off before getting in a pool or spa. Cover or remove while cleaning: household cleaners with acids or abrasives will damage your jewelry's finish.
Tip. Never use toothpaste, baking soda, or a commercial metal cleaner on gold. If you use these abrasives, you may scratch the gold. Never use bleach.
Simply pour the coke into a bowl and submerge your silver into it. The acid in the coke will quickly remove the tarnish. Keep an eye on it – just a few minutes should be enough. Rinse with warm water and dry carefully with a soft cloth.
To clean old rusty tools with Coke, submerge the tools in a tub or bowl of Coca-Cola overnight (not sure if Diet Coke or Pepsi will work – best to stick with original Coke). If you can still see rust, leave them for a few more days.
If a more thorough cleaning is needed, soak the jewelry overnight and use a very soft toothbrush with Dawn. That's it. This cleaning method will bring your jewelry to sunglass-worthy sparkle. (Please note – opals, coral, turquoise, pearls or other porous gemstones are not recommended for this cleaning treatment.)
Acids, like the weak acid present in your can of Coke, can react with oxides to effectively reverse the process of tarnishing. The acid dissolves the metal oxides that make the tarnish, leaving only shiny metal behind.
Dish Detergent & Warm Water
The best homemade jewelry cleaning solution is a mixture of a few drops of Dawn dish detergent in warm, not hot, water. Let the piece sit in the solution for a few minutes, longer if it's very dirty, then gently scrub with a new, baby-size, soft toothbrush.
The only way gold could truly be destroyed is through nuclear reactions. However, there does exist a way to dissolve gold using “Aqua Regia,” which is a mix of hydrochloric and nitric acids.
Gold is one of the least reactive elements on the Periodic Table. It doesn't react with oxygen, so it never rusts or corrodes. Gold is unaffected by air, water, alkalis and all acids except aqua regia (a mixture of hydrochloric acid and nitric acid) which can dissolve gold.
Salt and baking soda are a surprisingly effective combination for cleaning gold. When combined, they create a chemical reaction that helps break down tarnish. Use equal parts of each — say, one tablespoon salt and one tablespoon baking soda — as well as a drop or two of dish soap if you'd like, Martin says.
Look for Stamps or Hallmarks in Your Gold Jewelry
Most real gold is stamped with a hallmark that indicates its purity, aka its karat. The karat is the unit used to measure the purity of gold. The higher the karat, the purer the gold. The most common karats you'll see are 10k, 14k, 18k, 22K, and 24k.
Baking soda, salt and aluminum foil.
Mix one tablespoon salt and one tablespoon of baking soda and mix with one cup warm water. Pour into the dish. The mixture will create a chemical reaction with the foil and bubble as it cleans the jewelry. Rinse with cool water and buff dry with a clean cloth.
(The average pH of Coca-Cola, Pepsi, and other colas is 3.4.) Carbonation combined with the acid can dissolve the metal oxides and remove tarnish from copper, brass and other metal alloys. Citric acid is known to remove the stains. Phosphoric acid is commonly used for rust removal.
REMOVING STAINS
According to Good Housekeeping, Coke will remove blood stains, grease and gross odours from clothing. Just pour a can of the stuff in the wash and run the cycle as per usual - the Coke will lift out the stain and stink and wash away with it.
