I'll be interested to know what is suggested here.

Was that "how could he tell" it's bat pee?  Ruth

Subject: Removing bat urine stains from painted wood

I am working on a painted timber charity board (originally 18th
century, with subsequent repaintings) which has been kept since its
construction in an extremely damp parish church, with a significant
resident bat population. A thick layer of accumulated dust and grime
was removed relatively easily using first dry cleaning methods and
then a 15% tac solution, but white staining--which I believe is
caused by bat-urine--has proved impossible to clean with all the
usual solvents. Does anyone have any suggestions?
