Perhaps you could go to Google on your computer. Type in: "How to chemically remove rust from Iron."

Thank me very much.

 

Nice, thanks.

 

I would recommend this, but it may harm the coin?

 

Or WD 40 ...but i recommend olive oil soft cotton wipe...most probably the damage has been already done.

 

I guess the real question is "how can you remove rust from an iron coin without damaging the coin's surface", and the answer is most likely "you can't" -- rust is going to leave damage where it's consumed the iron.

I did get a jug of something from Lowe's that was a non-acid rust remover. In fact, I think it was prompted by a discussion here. I'll see if I can find it.

Edit: it was from Walmart, and the thread is here:

I got the stuff, but then it went over to my father-in-law's, so I haven't yet had a chance to try it out. When I do, I may hit my bicycle first, as it's in much worse shape than any of my coins, rust-wise.

 

Then tell us what you did and what you used. Try a soak first.

 

That coin is too far gone.

 

The iron in the coin has reacted to form iron oxides (and maybe other iron compounds). Removing the iron oxides will also remove the iron that used to be the surface.

Not a whole lot you can do to make it better

 

I think any effort to remove the rust will just make matters worse.

At best, keep the coin in a dry environment, with a packet or two of silicon. That should slow down the oxidation process or stabilize it.

 

Sadly the answer is you can’t

What is trying to be said is that the iron on the surface is now the rust. The question is " How deep into the surface has the reaction progressed. A small amount might still have significant details and worth the task of trying to remove. Deeper with visible pitting is probably not worth the trouble and expense. The value/rarity of the coin should be the determining factor for time and expense. Jim

 

Evaporust works well to remove rust and then stop it from spreading. You may have to soak it overnight. Then I would wash it bake it for a couple hours and rennwax it.

I use evaporust for car restoration work and it's probably the least destructive way to remove it.

 

Electrolysis is an option.

This was the best I could do with some rusty iron ore:



Edit, I've just checked and actually didn't use electrolysis on this. Vinegar, then Cif, along with a couple of rounds of heating until red hot and then dunking in iced water to shock the corrosion loose. This was the before picture:

 

Citric acid might be worth a try
