Algal and lichen growth following chemical stone cleaning
Young, M.E.
Algal and lichen growth following chemical stone cleaning - 1998 - Journal of Architectural Conservation 4(3) November 1998, 48-58(11) .
Discusses the results of a study into the growth of algae and lichens on samples of chemically-cleaned sandstones over a period of five years, which indicated that phosphate-bearing chemical cleaning methods should be used with caution on porous stone types in situationss where biological growths could cause problems.
