BD cleaning advice on Tiberius AE
« on: August 28, 2011, 10:32:34 am »
Hi all. I've been soaking this Tiberian AE in gringotts as per the advice I received from members

I had managed to loosed a lot of the green lumpy nastiness and remove it, esp. on the obverse. Generally, however, the green in the pits on the reverse, and the small amount remaining on the obverse haven't expanded or changed. Is this as much as I can do? Should I leave this clean as it is? Advice please!

I have also posted a link to the original thread. The original pictures there allow you to compare between the state of the coin then and its condition now from the more recent pictures I've attached to this post.

Thanks for looking!

The light green stuff will have to be manually removed. If it is bd, it will be easily scraped off using a strait pin, exacto, etc. I have yet to find anything that actually "eats" bronze disease (ie, you could soak it for a million years without manual cleaning and it will still be green and easily reactivated).

The stuff circled in black is what you need to concentrate on. That is where the bd is eating in to the coin. All of those pits will have to be cleaned out. The upper stuff (circled in white) is an old and non-active looking bloom (the green on top of the reddish chalky feeling stuff). You could reduce that down to the flan level, but the red will be IN the flan, so if you decide to reduce it, make sure you stop at flan level otherwise you will have a divot in your coin after finished.

Edit: The way to do it is: manually clean, soak overnight, manually clean, soak overnight, repeat until all the pits are cleaned out (changing the bd soak water every other day or so), then let it sit out in your normal enviorment for a month or so to see if anything reactivates. If not, call it done, if so, repeat as needed.
