Methylene chloride can be found at Home Depot and Lowes. They are sold as varnish removers. Just look at the ingredients. You will see MC on the label along with other solvents such as Naptha ,etc.<br><br><div class="gmail_quote">

Partners,<br>
Over past few months I tried to poultice out siliconized calking stains out of sandstone. I was encouraged seeing improvement after first 2 applications (poultice with MEK) however the third one (HG oil remover from scc) and forth one (MEK again) did not produce any significant improvement. Is there anything else I can do or is it safe to say that it is permanent and farther applications will not work?<br>
