Subject: cleaning lichen from monuments and lead paint

  The Littleton Historical Commission would like advice on cleaning what I think is lichen from a historic monument in town.  The monument is granite from about 100 years ago and has inscriptions that are becoming illegible because of growths of lichen covering them.  What do you recommend for cleaning the monuments?  Is this something that amateurs can do, or are there professionals whom we should call upon?  If the latter, can anybody recommend someone or suggest listings of reliable professionals?
  On the lead paint question--We had our home repainted last year.  Our contractor was aware of the lead paint ruling (just coming into force then), took a brief course on the requirements, and then followed them.  I'm sure that any reputable painting contractor would now be prepared to follow the requirements.  You probably shouldn't have to tell them what to do.
Thanks
