Try going to a beauty supply store and get the strongest peroxide you can get. It&#39;s inexpensive and might work. It&#39;s great for a poultice also.<br><br><div class="gmail_quote">On Thu, Mar 22, 2012 at 11:27 PM, Michael and Tammy <span dir="ltr">&lt;<a target="_top" href="mailto:daci6537@comcast.net">daci6537@comcast.net</a>&gt;</span> wrote:<br>

<div><font face="Calibri">Does anyone have any suggestion on cleaning this cast 
stone? Picture 042 is a area that was able to be treated with 
chlorine and pressure washed. However Picture 027  was another area I tried 
chlorine and a heavy degreaser with a pressure washier and scrubbed with a power 
scrubber with a brush.  Nothing seems to work.  </font></div>
