Cleaining Ancients With Hydrogen Peroxide

So right now I have some more uncleaned ancients in some peroxide and hope to show some results soon.

Has anyone else had some great results with the stuff in the past few weeks?

Aktina- Great! I am glad to hear it! Honestly, I just stumbled upon the method, but I am happy to help everyone out.

Please do post some pics when your coins have shown a lot of progress!

I tried it. It is much faster than peroxide, but it is potent. You have to keep a VERY close eye on your coins because it can quickly and easily remove the patina if you don't. I suggest you put only very dirty/crusty coins in it and avoid soaking coins that have patina showing or may have brittle patina. Other than that it is very effective!

Here's some photos of a coin I worked on last. The first photo is the uncleaned original. The next 3 show the coin after 5 minutes in my cleaner. Between each soak, I take a Q-tip to remove dirt, then use a nylon bit on my trusty dremel.
All in all, I think it turned out well...?

Yes, that is how it reacts to the red corrosion in the same spot that you often see on bronze coins. In the 4th photo, you can see that it's pretty much gone, after using a bit of Renaissance wax. With green corrosion, it's effective at softening it up so that you can wipe it off with a Qtip.

Gil-galad- Even just for hydrogen peroxide a lot of cemented dirt and other substances gradually bubble away. But if nothing is underneath the grime, then that is all that you will get. I have found that for coins that have A LOT of stuff stuck to them that you kind of have to gradually wear away the layers. the peroxide usually just maintains its efficacy for about a day or two before it is just smelly water. So each time that I change the peroxide, I give the coin a scrubbing with a Q-tip. Each time more crud is scraped off, and this way a much more solid layer of dirt is exposed to the peroxide.

Peroxide can be a very effective cleaning agent, and works very well with the method described by Archraz. A word of caution, however: peroxide will have a tendency to "bleach out" some coins, and can also cause serious skin irritation. This is especially true where coins are exposed to peroxide for a prolonged period. If I always practiced what I preach, I would never leave coins unattended in my solution or peroxide, and I would always wear gloves. Unfortunately, I'm guilty on both counts, and sometimes pay with blistered fingers and overcleaned coins...

Here is what it looked like before cleaning.
