Do you think NCS can help these medals?

I posted to the conservation subforum but forgot it's moderated.

 

Do these look salvageable? My skillset stops with acetone and olive oil...and wouldn't touch aluminum with a 10 foot pole.

 

Iron, with white spots

 

Aluminum

 

Slabbed

 

Generalized spots and gunkyness:

The third coin down looks like it could helped, and the spotting/gunk on the fifth coin down could probably be lessened somewhat IMO. The others I would leave alone but that's just my opinion.

Thanks Dragon . The third one down is the one I'm most worried about.

 

Medals are kind of fun in that I can tolerate a whole different level of condition...but I don't want stuff that keeps propagating or is a surface 'schmutz' that can keep causing damage.

 

I'll probably send a few in (especially #3) and see what happens. It's only money, and if there is nothing to be done, no big deal. Well, I won't send in the aluminum one, it's literally a $15 piece and I can't really justify the minimum charge on that one as they are pretty common.

From what I know about NCS---they may not be able to completely remove the problem areas but they can lessen their appearance and make sure that they're stable.

 

However, the entire medal would be treated and this WILL permanently alter it's existing surfaces....by how much; I don't know, as it seems to vary, so you have to make sure that you're OK with that.
