I have a slate project also with etching.  At some point the customer&#39;s father used muratic acid to clean off efflorescence.  I have tried using a color enhancer to solve the problem but the color enhancer only highlights the etched areas.<br>
<br>Any suggestions?<br><br><div class="gmail_quote">On Mon, Oct 19, 2009 at 9:12 PM, John Freitag <span dir="ltr">&lt;<a target="_top" href="mailto:jfreitag@thestoneandtileschool.com">jfreitag@thestoneandtileschool.com</a>&gt;</span> wrote:<br>
