Statement from Dennis Montagna - Vice President & Conservation Committee Chair, Association for Gravestone Studies:
Shared with Permission:
"We
neither support nor condone the aggressive cleaning of cemetery
monuments, whether through mechanical or chemical means. Moreover, in my
nearly nearly thirty years in the preservation field, I can't think of a
single case in which the use of power-driven brushes made sense as a
stone cleaning tool. In fact, Nyalox brushes are typically impregnated
with aluminum oxide abrasives, so they would have an especially
devastating effect on calcareous stones like marble, limestone and some
sandstones."
