It's wise to be cautious when trying this on jewelry, as the acid in Coke can also strip paint and rust off metal if left long enough. Remove the jewelry and promptly rinse. For something a bit safer, you may want to stick to cleaning jewelry with aluminum foil instead.
Let the silver soak for 1 hour.
Leave the silver in the Coke undisturbed. The acid in the Coke will help loosen any grime and residue from the silver. If you want to leave the silver in the Coke to clean it longer, keep it submerged for up to 3 hours.
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.
Coke is an ideal cleaning substitute for cleaning chemicals for both sterling and plated silver. The acids in the drink cut through grime or rust that has built up and can leave the pieces looking as good as new.
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.
Coca-Cola is carbonated, which allows it to dissolve with metal oxides and break up rust on a variety of metals and alloys. Phosphoric acid also gives it rust-busting power, while citric acid makes it an effective stain remover.
The high sugar content and carbonation of Coke can potentially damage the metal and gemstones of the Pandora bracelet. Instead, it is best to clean your Pandora bracelet with a mild soap and warm water solution. Gently scrub the bracelet with a soft toothbrush, rinse thoroughly, and dry with a clean cloth.
Mix a paste of roughly 3 parts bicarbonate of soda to one part water and apply to your silver jewellery, taking care to avoid stones or pearls. Rub the paste into the silver with a lint free or microfibre cloth until you see the shine starting to return.
Chlorine can damage and discolor metals (like gold and platinum) and can slowly erode the finish and polish of gemstones. Before playing in the sand (or gardening.) Dirt and small rocks are abrasive. If not cleaned right away, your jewelry can be permanently damaged.
Harsh chemicals like chlorine, acids, sulfur, and salt can damage or discolor gold,1 particularly items less than 24 karats. Chlorine can weaken your gold jewelry's structure and eventually lead to its breaking. Avoid exposing gold jewelry to hair sprays, make-up, medicated lotions, and creams.
Be mindful of your gold rings, watches, and bracelets while you wear them and remove them while playing any high-contact sports. Chlorine is gold's worst enemy: with repeated exposure, chlorine will weaken your gold jewelry's structure and eventually lead to it breaking.
Clean silver jewelry with Coke or a carbonated beverage.
Let your jewelry soak in a bowl of carbonated liquid for about ten minutes. Then, remove the jewelry, brush it with the toothbrush, rinse it, and lay it out to dry.
Scratch test.
If you cut deep enough that you expose underlying metal, you can assume that it is plated. If it appears to be made of a uniform composition throughout, then it is probably solid gold.
The bottom line is that simply by wearing your Pandora jewelry, the pieces will slowly tarnish. Don't fret! Tarnishing is a natural effect with silver metals and is in no way permanently damaging to your jewelry.
WD-40 works quickly to polish and protect fine silver plates, platters and even silverware. The oil compounds in WD-40 break up grime, leaving a thin layer of protection against tarnish.
While cola is good for removing tarnish on some metals, on others such as iron, tin and steel, it can corrode the metal.
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.
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.
