Cleaning detector find badges/buttons

[Chats1]

Hi there,

My Grandfather found a couple of buttons a few years back whilst metal detecting.

From remaining loophole fixings at the back they look early 19 century and seem to be pewter.

However, they are so corroded that it is impossible to make out anything to be able to identify them. I've attached a photo of both (front and back) not that it makes much odds! The first seems to have some marks that make a circle but that's about it.

Does anyone have any tips on how to best make any attempt to glean some detail from them and reduce the damage, or are they to remain an interesting mystery?! I've heard tips about dipping them in coke etc.

Thanks

I use coca cola, only on rusted items, I use a Dremel, first the plastic brush and later a fine brass one

an6 if you can find it. Industrial descaler that is enviromentally safe. Just don't use it on galvanised or aluminum. I've tested it on Brass, W/M, Bronze and Copper. It works a treat.

Different metals will react to different chemicals. Also make sure you rinse the object in (preferably distilled) water afterwards to ensure that the chemical is not continuing to "clean".
If you log your finds with the Portable Antiquities Scheme http://finds.org.uk/ it will help create an interesting database of military finds - there are already badges and buttons on it. NO they won't take anything away from you !!
