isopropanol resulted in only 27 mgs. of gold metal becoming dissolved. In comparison therewith the use of ethanol in the identical system resulted in the dissolution of 2,062 mgs.
If you have any jewelry that's made from a real precious metal such as silver or gold, you can clean it safely with alcohol. As long as your jewelry is made from these metals, the jewelry won't be damaged, whatever its karat or quality.
Gold dissolves quantitatively in ethanol using 2-mercaptobenzimidazole as a ligand in the presence of a catalytic amount of iodine.
Rubbing alcohol can damage fake gold if it is used improperly, and it can cause discoloration. To clean fake gold with rubbing alcohol, put some of it on a cotton swab and gently rub it in circular motion onto the surface of the fake gold. To avoid damaging the fake gold, take extra caution not to scrub too harshly.

If you ever share earrings with a friend or purchase them from a store, it's recommended that you soak them in alcohol before using them.
Gold may be dissolved using aqua regia or royal water, which is nitric acid, combined with hydrochloric acid at a ratio of 1:3. Hydrochloric acid is commercially available as muriatic acid. Nitric acid is restricted and must be prepared using available chemicals.
Alcohol-based sanitiser doesn't cause immediate damage, but the buildup of residue could cause metals to tarnish and wear over time. Yellow gold is the least susceptible to damage from hand sanitiser, because there's no layer or film that can become tarnished or worn.

Aqua-regia is reagent is able to dissolve gold and platinum.
Although gold is typically an inert metal, it will dissolve in aqua regia because of the unique action of nitric and hydrochloric acid. Nitric acid is a powerful oxidising agent, capable of converting small amounts of gold to its ionic form, Au3+.
99% isopropyl alcohol has the benefit of being non-corrosive to metals or plastics, so it can be used widely, on all surfaces, and won't leave smears, even on glass or screens. As an industrial cleaner because it does not leave a residue that may cause complications in manufacturing.
You will need a small bowl or container, rubbing alcohol (at least 70% isopropyl), and a pair of tweezers. Step 2: Place earrings in the bowl and pour enough rubbing alcohol to cover them completely. Step 3: Let the earrings sit in the alcohol for a minimum of five minutes.
Like most alcohols, isopropyl alcohol reacts with active metals such as potassium to form alkoxides that are called isopropoxides.
Yellow gold is the least susceptible to damage from hand sanitizer because there's no film or layer that can become tarnished or worn down. Platinum is another fairly safe metal.
Can I clean my gemstones with alcohol? In most cases, the answer is yes. For most precious gemstones such as diamonds and rubies alcohol is a perfect solution for cleaning. Gems considered to be precious are harder and more durable, making them ok for cleaning.
Acid test.
An acid test can reveal the karat of solid gold jewelry, but it can also show whether jewelry is solid gold or gold-plated. With an acid test, a small sample of the jewelry is removed and exposed to acid to induce a color change. The resulting colors indicate which type of metal the jewelry is made of.
Use Nitric Acid
If you have a circuit board with gold plating, you can remove the gold using nitric acid. The acid will dissolve the metal and leave the non-metallic components of the circuit board intact.
