<TD width="100%"><FONT face=Verdana color=#ff0000 size=2>, <BR>Answer
<B>NO</B>. Household bleaches (which includes Mr Clean) often contain
sulphates and may cause exfoliation of the surface as these salts dry out
and recrystallize in the surface pore structure.<BR>Bleaches can also
produce light brown staining after a period of
time. <BR>Try:<BR>First, using clean water, dampen the entire stone
gently without disturbing the dirt.<BR>Once the stone has been saturated,
use plenty of clean water and scrub the surface lightly and carefully with
a soft natural bristle brush just hard enough to lift the surface
soiling. <BR>Cover the stone with a paper poultice and allow to dry
completely, this will ensure that dissolved particles are deposited in the
paper and not returned the surface of the stone.<BR>Wash well with clean
water. </FONT></TD></TR></TBODY></TABLE></DIV>
