Thanks for the quick ID Iron Patch, and thanks for all the other comments too. I knew I could count on you guys to help.
I am extremely hesitant to clean this button... I fear that the entire face will flake away and I will be left with no detail.
I have never gave a button a peroxide bath. Do you think it will help?
Once I work up the nerve, perhaps I will attempt a cleaning.
A light brushing you say... with a brass brush, or soft toothbrush?
On something like that peroxide is quite safe because it will work very slow and you can stop the process at any time. So for that particular button the possible benefit would far out weigh the risk. In fact, if that stuff on there is very hard (difficult to tell from the pic) the hp might not even have an effect. If the process is working it will gradually start to clear the crud and reveal more of the design. If you decide to that's definitely safer than attacting it with anything else. Buckleboy has a point if about using a toothpick if it will remove material without being too aggressive. I rarely use a toothpick, or feel I have too, but that's just a matter of different methods and opinions.
The primary reason I toothpick is to create a contrast between the background fields and the raised or stamped-in design. I do not use it to remove crust.
That said, it is usually the case that a brass button's design is intact below the crust. Copper coins are another story, but I have found brass to be generally fine. The button in question has a design that is not very high relief, so any detail or contrast lost is too much. If it were a one-piece eagle button that crusty, I'd toothpick away. But I am hesitant to give advice on this one.
When I toothpick, I either leave the patina in the fields and remove the crust from the design, or I remove it all together with dry brushing, then bring out the design with oil from the fingertips (which is always the final step--since I have found that any oil seems to bind with the crust/dirt and makes it almost impossible to remove at a later date).
