Metal detecting is a fun and rewarding hobby that can lead to some truly unique finds. But if you want to keep those finds looking as good as possible, it’s important to understand the best practices for cleaning them.

In this article, we’ll explore the different cleaning methods for metal-detecting finds, as well as tips and warnings to keep in mind while cleaning. We’ll also look at the statistics and miscellaneous information involved in cleaning finds.

So, if you’re looking to get the most out of your metal detecting finds, read on and learn how to properly clean them.

Precious Metals

Precious metals, such as gold and silver, can be difficult to restore due to their resistance to corrosion, but with the right methods, they can be brought back to their original shine.

One of the best ways to clean metal-detecting coins, such as quarters, is to use a coin tumbler cleaner. This is a device that uses a combination of abrasive and non-abrasive cleaning solutions to gently remove dirt and grime from the coins. It is important to be careful when using a coin tumbler cleaner as it can cause damage to the coins if left in the solution for too long.

Another great way to clean metal detector finds is to use an ultrasonic cleaner. This is a device that uses sound waves to break down dirt and grime on coins. Ultrasonic cleaners can be expensive, ranging from $50-$5000, but they can be very effective when used correctly.

It is important to check the coin periodically with a jeweler’s loupe or magnifying glass to make sure it is not damaged by the cleaning process.

While some skeptics may think ultrasonic cleaning is a waste of time, the results can speak for themselves. Cleaning metal detecting finds can be a rewarding experience and can bring out the original beauty of coins, even those that are not rare and hold only sentimental value.

It’s important to be careful and consult a professional if you are unsure of how to clean your finds or if they may be valuable.

Iron Relics

Rusty iron relics can be a challenge to restore, but with a bit of patience, they’ll be ready for display in no time! Metal detecting finds can be a fun and exciting way to uncover treasures, but it’s important to keep safety and preservation in mind.

Here are some tips on how to clean iron relics found in the ground:

  1. Use dish soap and warm distilled water to clean the relic.
  2. Soak the relic in olive oil or mineral oil to remove caked-on dirt.
  3. If the relic is heavily corroded, use a rock tumbler to gently remove the rust.
  4. If the relic is particularly fragile, an ultrasonic cleaner can be used with a non-abrasive cleaning solution.

It’s important to remember that cleaning methods can be damaging to coins, so it’s best to consult a professional for any valuable finds. If you’re looking for a safe and effective way to clean coins, hydrogen peroxide is a great option. Just be sure to keep an eye on the coin and periodically check it with a jeweler’s loupe or magnifying glass to make sure the cleaning process is going well.

With some care and patience, you can restore your iron relics and have them look as good as new!

Cleaning Methods

With the right care and attention, you can bring your buried treasures back to life! Cleaning metal-detecting finds is an art form, and with the right tools and techniques, you can get your items back to their original glory.

There are a few tried and true methods for cleaning coins, jewelry, and relics that you’ll find while metal detecting. Dish soap and warm distilled water are the safest options for cleaning your finds. This method is mild enough to be used on precious metals, but will still clean off dirt and grime.

If your coins are caked in dirt, you can try soaking them in olive oil or mineral oil to loosen the dirt. Hydrogen peroxide can also be used, but be careful not to leave it in too long as it can eat into the coin.

Rock tumblers are a great way to get your finds clean without the risk of damaging them. They use a combination of water, grit, and motion to clean and polish your coins. Ultrasonic cleaners use sound waves and a non-abrasive cleaning solution to restore your coin’s shine.

While it may take longer than other methods, it is the safest way to clean your coins. So, if you want to get your finds looking like new, consider using one of the above methods.

Tips and Warnings

Before you start cleaning, take heed of these tips and warnings!

First, olive oil contains fatty acids that can attack a coin, so it’s best to avoid it when cleaning metal detecting finds.

Second, it’s important to periodically check the coin with a jeweler’s loupe or magnifying glass to make sure it is not being damaged.

Third, be aware that copper pennies will turn other coins reddish-brown, so it’s best to separate them out.

Lastly, it’s always best to err on the side of caution when it comes to cleaning coins found metal detecting.

The best way to clean quarters, nickels, and other metal detector coin finds is to use a combination of dish soap and warm distilled water. This is the safest method since it won’t damage the coin.

If the dirt is caked on, an olive oil or mineral oil soak might be necessary. It’s important to remember not to leave the coin in the soak for too long, as this can also cause damage.

When it comes to how to clean an old nickel or other metal-detecting coin finds, it is important to find a method that works for you.

While it is tempting to use a rock tumbler, hydrogen peroxide soak, or even an ultrasonic cleaner, it is important to remember that not cleaning finds is best for maintaining value.

If you are dealing with a valuable find, it’s best to consult a professional beforehand.

If used correctly, these methods can result in a beautiful and valuable coin, but if used incorrectly, they can cause irreparable damage.

So, be sure to take your time and be extra careful!


Not only is metal detecting exciting, but it can also be lucrative if you know the value of the coins you find! Ultrasonic cleaner units range from $50-$5000, so it’s worth doing your research before investing in one.

For the dedicated quarter hoarder, a mid-range metal detector with a metal detecting for coins feature may be a great place to start. If you find yourself wanting to identify old metal objects or rare metal detector finds, you may need to invest in a high-end model.

No matter the model, you’ll want to make sure you know what you’re getting and how to use it. Many people use a rock tumbler to clean common finds, and some use a metal detecting finds display case to show off their finds. But if you really want to get the most out of your metal detecting hobby, you should consider an ultrasonic cleaning unit.

Ultrasonic cleaning uses sound waves and a non-abrasive cleaning solution to safely clean coins and other finds. While the skeptics may think it’s a waste of time, there are many who swear by it.

Just remember to be careful and consult a professional for valuable finds. Teknetics isn’t liable for damages.
