But I persevered nonetheless, and not even with my Dyson which is very good and not putting particulates back out, but with a little inecpensive vacuum cleaner (quite powerful) I use for cleaning out customers' pianos.  I can only hope that since I dont do this often, there is no cumulative ingestion of lead compounds..... Best regards, David. <blockquote type="cite">I would be very apprehensive about vacuuming up the dust of oxidized lead.  What this does is take all the fine particulate matter and blow it through the filters and out the back end, spreading all of it into the air.  From there, this super fine particulate matter gets inhaled deep into your lungs. This stuff is not to be trifled with! Jurgen Goering</blockquote> </body> </html>
