Welcome to the forum Das.
It is possible to remove the soldered parts, it is also possible to restore them fully. It depends on what you're doing with them, if you're making a quick buck then just sell them, if you bought them cheaper than melt. If you want to restore fully, it's probably going to cost you more than the value of the 2 of them.
There's a thread here somewhere, I'll find a link. From what I remember, the guy takes a good 6 months to a year for a full restoration.
