Insightful Tips on How To Practically Clean Old Coins
1- Quick ways to clean copper coins:

a- Ketchup

All you require is to take out a bottle of ketchup from your fridge and gently smear a little on your coin. Gently scrub on the coin with a toothbrush, working through all fine areas. You can rinse the coin under warm water. The coin might look a little weird – some pinkish color. Make a mixture of baking soda and some warm water which will create a paste. Gently rub this concoction around the coin with your fingers. In no time the coin will have its shine restored. 

b- Taco Bell taco sauce

You can repeat the same process using the taco sauce as you did with the ketchup. If the coin acquires the unusual pinkish color, use the baking soda paste to restore its shine.  

c- The same process can be replicated with Tabasco sauce.

All the processes mentioned above are similar because the substances used all contain salt and vinegar. This main ingredients are two frequently overlooked items within the house. To prove the effect of vinegar and salt you can try them out. You require a quarter cup of vinegar and a teaspoon of salt not forgetting the mixing bowl. Insert the penny into the solution for roughly 5 minutes. Now you can rinse the pennies to prevent further reaction between the vinegar and salt solution and the pennies. If you do not rinse them out they will continue reacting with oxygen. They will begin turning bluish-greenish. 

d- Digital Ultrasonic Cleaner

This electric device is capable of cleaning your old coins as well as jewelry. It operates on ultrasonic waves and warm tap water. If you are to use this device, I recommend a copper cleaning solution. 

Note: Sometimes you might experience varied color results when you mistake old bronze pennies to be copper. This mostly arises from nickel being replaced by zinc and tin.


2- How to Clean Silver Coins:

When silver coins are exposed to the atmosphere they develop a black or brown oxidized layer. This is mainly caused by atmospheric sulfur. 

a- Lemon acid

Insert the coins into the lemon acid solution for a duration that will depend on how thick its oxidation layer is. After cleaning out the coin using a soft brush rinse with water while drying it out on a soft paper. You can make the method more effective by inserting some iron nails into the lemon acid bath. 

b- Acid Fluid

If the coin has a few oxidation spots then the best way to do a quick clean is by using sour milk or warm vinegar while placing them on a raw potato that has been cut in half. 

c- Use silver cleaners

The silver cleaning products on sale are used for cleaning oxidized silver coins. In a matter of seconds the silver stain will be cleaned off the coins. This method is quite thorough so unless you really know what you are doing its advisable to use the other two methods.

3- How To Clean Gold Coins:

Gold jewelry has a lot of significance to its owner and may be used as a gift due to its sentimental value. Occasionally one must clean their gold jewelry. You can either opt for special professional cleaning products or home cleaning methods. Here are a few simple home cleaning methods that can be practically done.

Dish detergent – You can use dish detergent mixed with warm water. If your jewelry does not contain any gemstones, it may be soaked in soapy warm water for a quarter of an hour then thoroughly rinsed. If the jewelry is lined with gemstones do not submerge it as it will loosen the gemstones. Instead utilize a soft damp cloth set in soapy water. This rinses off the soapy solution. 

Bristle Toothbrush – Gold jewelry may contain spots which are difficult to reach completely. This method requires the user to use a soft bristle brush that will not scratch the jewelry. Simply dip the brush in a soapy water solution and scrub accordingly.

Ammonia – As much as ammonia is a great gold cleaning solution, it is also very risky if improperly applied.

Alcohol – Alcohol is a great solvent for removing grime and residue from the jewelry. It’s way better compared to using boiling water or strong chemicals. The only concern that arises from using alcohol is that it may loosen the adhesives binding the gold to the gemstones.
