Introduction: Removing Corrosion on Old Coins / Small Metal Objects
Last year in my town, there was a small construction site, and they ended up dumping loads of extra excavated dirt down a hill. My brother and I decided to explore and see if there were any Native American arrowheads that may have been dug up in the process! We found no arrowheads, but what we did discover was a small medicine bottle from the 1940's or so. We returned to the spot many, many times, and found loads of antique glass bottles, along with a World War Two button. Along the way I collected a coin shaped object, but it was so heavily corroded I was unsure if it was worth keeping.
After about a year of the unknown object sitting around, I decided to try to create a solution that would remove the corrosion, and possibly reveal what it actually Is. To our surprise, the corrosion was quickly removed, and the object turned out to be a 1943 silver nickel!
I hope that this solution I came up with will be as helpful to someone else as it was for me!
Step 1: Introduction
So.. You have a very corroded object like the one shown in the picture. But, you dont want to spend much time or effort removing the corrosion. Well what if I told you that you CAN remove the corrosion very easily, using materials found in almost EVERY house! Sounds pretty good huh? Why dont you give it a shot!
Step 2: What You Will Need..
You will need..
· Object with corrosion
· Glass jar
· Measuring cups
· White vinegar
· Lemon / lime juice
· Iodonized table salt
After you have all of these materials, you are ready to begin!
Step 3: Mix Ingrediants..
-Pour into your glass jar -
·1/2 cup of white vinegar
.1/2 cup of lemon / lime juice
·3 table spoons (tbs) of iodonized table salt
- Continue mixing until the salt is completely dissolved in the solution.
Step 4: Patience!
Let your corroded object sit in the jar until the corrosion is gone. If you wish to speed up the process, you may take the object out and gently scrub it with a brush, then return it to the solution and wait. After you believe the corrosion has been removed, remove the object and dispose the solution properly.
Step 5: Done!
Your corrosion should now be removed!
