<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">My client has a Limestone floor that was installed about a year ago.  Some of the stones are turning dark, others are not.  In some areas al the Limestone is turning dark.  The homeowner used Miracle Sealants 2 part poultice.  It required 5 applications and scrubbing to lighten the stones.  Honing did not lighten the stones.  The Limestone was sealed with 511 Porous Plus after it was installed.  There is a moisture barrier and the thinset used was white.  We are trying to figure out a way to clean and lighten the stone to its original color.  Miracle Sealants 2 part liquid poultice is very harsh and melts both blue and vinyl tape.  Any ideas would be appreciated.<span class="HOEnZb"><font color="#888888"><br clear="all">
