Fill one of the plastic containers with two cups of the distilled water. Stir in the mild hand soap and stir to create a soapy water mixture. Put the coins you want to clean in the container and allow them to soak for 10 to 15 minutes.

Take the coins out and place them on the clean, soft cloth. Using the old, soft toothbrush scrub the face of the coin softly. Place the coin in the second container filled with the remaining distilled water.

Allow sitting for five to ten minutes. Remove from the bin, place on the soft cloth and allow to dry naturally.

2. Cleaning Everyday Coins

You should not use this technique on coins that have a valuable patina because it can damage the coin, rendering it worthless.

7 Tips On How To Clean Coins

You can clean your coins without damaging them by soaking them in a bath of isopropyl alcohol and salt. When combined, these ingredients are both abrasive and acidic and will clean any built-up dirt off your coins.

To make the coin bath, you will want to combine one cup of isopropyl alcohol with two tablespoons of salt in a medium-sized bowl.  Mix the solution and add your coins to the dish. Let them soak for at least two hours.

If they are filthy, you may have to allow them to soak for up to a week.

Rinse the coins, using distilled water. Avoid using tap water because it contains chemicals that will, over time, erode the coins. The purified water will rinse off any leftover chemicals from the coins.

4. Cleaning Coins with Olive Oil

Using olive oil to clean your coins is a simple and inexpensive technique. The olive oil can penetrate the dirt on the surface, loosening it from the currency. To use this technique, you’ll need a plastic container and some olive oil.

After the coin has sat in the olive oil, remove it from the bowl and clean the coin with soap and distilled water, gently scouring the currency with an old toothbrush.

How to Clean Pennies

Cleaning pennies can be a bit of a challenge because there are different methods to use depending on the creation date of the coin. Pennies that were made before 1982 are made with more copper, leading to a more intense chemical reaction. Make sure any brass polish or coin cleaner you are using does not damage your coins.

If you have any pennies that were created before 1982, it’s best to check with a coin dealer to determine if it is valuable.

If it is a valuable coin, it’s best not to clean it to avoid damaging it and reducing its value. However, if the pennies you have were minted after 1982, here’s how to clean a penny with simple, everyday ingredients:

5. Vinegar and Salt Method

If you want to create a bright orange-coppery color, here’s how to clean a penny using vinegar and salt. You can also use lemon juice as a substitute for the vinegar if you don’t have any white vinegar in your pantry.

The low levels of acid in the lemon juice or vinegar are used to remove the patina that tends to form on older and dirty pennies.

DIY Penny Cleaning Recipe

  • ¼ cup white vinegar or lemon juice
  • One teaspoon table salt
  • Spoon
  • Small plastic container
  • Distilled water
  • Soft, dry cloth

Add the vinegar or lemon juice to the plastic container. Stir in the salt. Continue to stir until the salt dissolves.

Place the pennies in the bowl, making sure you don’t stack them on top of each other. Allow them to sit for five minutes. If they aren’t as bright as you want them, allow them to soak for another five minutes.

Remove the pennies from the cleaning solution and rinse under distilled water. Use the soft cloth to dry the pennies gently.

6. Baking Soda Method To Clean Old Coins And Jewelry

Baking soda is often used as DIY jewelry cleaner and in homemade metal polishing solutions. Place two tablespoons of baking soda in the bottom of a small bowl. Begin to add water until you have a thick paste.  

Using your thumb and forefinger, grab some of the paste and apply it to the penny. Gently rub the mixture onto the front and back of the penny, using small circular motions. Rinse the penny with distilled water and dry with a clean, soft cloth.

7. Cleaning Copper Pennies With The Ketchup Method 

While it may sound a bit weird, you can clean your copper coins with ketchup. The acid found in tomato ketchup will help to remove any oxidation that has formed on the currency.

To start, place about ¼ cup of ketchup in a small container. Next, dip an old toothbrush in the ketchup and, holding the penny on a flat surface, begin to scrub the ketchup into the surface, using small circular motions. Continue to do this for one minute.

Rinse the remaining ketchup from the surface of the coin by running it under warm water. Finally, dry the penny with a clean, soft cloth.

Cleaning your coins can be a fun and enjoyable experience when you know what you are doing. It is essential that if you think that you may be in possession of a valuable coin that you don’t try any of the methods listed above until after you’ve talked to a coin specialist because cleaning valuable or ancient coins could result in damaging them and lowering their value.
