Randy Silverman encountered smoke damaged books at a county records
office. He worked with a company that uses dry ice blasting. Randy
wrote an excellent article in Archival Products News, Volume 15, No.
3 2008   about his experience. He explained the
process of cleaning the soot from book covers. Perhaps dry ice would
work in your situation.
