you can poultice forever and I dont think you will get all the iron out of there.<br><br><div class="gmail_quote">On Wed, Jun 29, 2011 at 7:37 PM, Baird Standish <span dir="ltr">&lt;<a target="_top" href="mailto:bairdstandish@gmail.com">bairdstandish@gmail.com</a>&gt;</span> wrote:<br>

I am dealing basically with a soot/rust problem (see picture below).  There is an iron/steel grate in the <span style="background-color:rgb(207, 223, 229);color:rgb(82, 81, 81);background-repeat:initial initial">fireplace</span> that we removed.  there are many brown spots along the border of the <span style="background-color:rgb(207, 223, 229);color:rgb(82, 81, 81);background-repeat:initial initial">fireplace</span> box.   We honed the hearth to 50 grit (marble) and treated the spots about 5 times for 5-10 minutes with rsr 2000, and then poulticed for a few days.  The spots are a little lighter but still there.  Anything more I can do other than continue poulticing?  thanks,</div>
