I am tempted to use the Ultra sorb and would be careful, but I am cautious. People from my generation used asbestos in their homes on the bottom of hot pads and lead for Christmas decorations. My Dad was on a ship for bomb tests and they hosed off the radiation ha ha. Sometimes the dangers come out later. I'm not being over cautious.
