John Canning & Co.’s main mission in conserving the Sky Mural was to stabilize the existing finishes, remove the heavy buildup of soot and grime created by the exhaust of the train engines and air pollution (but NOT cigarette or cigar smoke), without damaging the finishes. Our conservators spent several weeks developing an aqueous cleaning agent that completely removed the dirt, without harm to the artwork. Only a few areas required paint and gilding touch ups.
