**UPDATE**CLEANED CONNECTICUT CIVIL WAR BUTTON

[HEAVYMETALNUT]

I tried the amonia bath repeatedly that was reccomended by another forum member Waterhead. it did do some improvement for this heavily green encrusted button but,not the result I had anticipated.
I decided to dig out the bottle of CLR and plopped it in. worked on it for about an hour and VOILA! looks a lot better now!

Excellent cleaning on the Conn button, may have to try that CLR sometime in the future. I have a site where if you find buttons or coppers, they seem encrusted in a lime like stone hard coating that previously I had to pick away with skewers to even be able to identify, so if I find any more buttons or coins there, it might give me the opportunity to try CLR.
