"CLEANING DON'TS

  a.. Wire brushes, metal instruments, abrasive pads (Scotchbrite, Brillo, Steel wool)  

  b.. Acid or acidic cleaners (especially on marble or limestone!)  (Should only be used by conservators with proper training on non-calcareous stone) 

  c.. Household cleaners:  soap (Ivory), detergents (liquid or powder), Borax, Clorox, TSP, Calgon, Fantastik, Formula 409, Spic and Span (or any other abrasive cleaner) 

REMEMBER:  The use of improper cleaning materials and practices can cause serious and irreparable damage to gravestones!  Make sure the stone is stable before attempting to clean it - no flaking, delaminating, etc."
