Hi, I thought someone on the list might be able to help.  We have a stone, 
mostly granite, fireplace, constructed in 1914 that recently sustained some 
damage.  When our new HVAC was installed, one of the units was vented 
through the chimney which led to condensation forming inside the chimney.  
This caused some sort of sappy substance to leach through leaving stains and 
damaging the patina.  As this damage is very visible and inside the house we 
would like to restore the chimney's appearance if at all possible.  We've 
already fixed the venting problem (by relocating) but can't figure out how 
to remove or at least reduce the staining and restore the patina.  Any help 
would be greatly appreciated.

Thanks,
Meghan McGinnes
