The other question arising is whether the chemicals in Downy will be corrosive to the strings.  That would not be good, however, they are pretty old as well. The bottle only states the ingredients as "biodegradable fabric softening agents (cationic)" (whatever that means!)..   :>() Paul <o:p></o:p> <table class=MsoNormalTable border=0 cellpadding=0 width="100%" style='width:100.0%'> <tr> <td width="40%" valign=top style='width:40.0%;padding:.75pt .75pt .75pt .75pt'> "Jim Busby" <jim_busby@byu.edu> Sent by: caut-bounces@ptg.org <o:p></o:p> 03/30/2007 07:30 PM <o:p></o:p> <table class=MsoNormalTable border=1 cellpadding=0> <tr> <td valign=top bgcolor=white style='background:white;padding:.75pt .75pt .75pt .75pt'> Please respond to College and University Technicians <caut@ptg.org><o:p></o:p> </td> </tr> </table> <o:p></o:p> </td> <td width="59%" valign=top style='width:59.0%;padding:.75pt .75pt .75pt .75pt'> <table class=MsoNormalTable border=0 cellpadding=0 width="100%" style='width:100.0%'> <tr> <td valign=top style='padding:.75pt .75pt .75pt .75pt'> To<o:p></o:p> </td> <td valign=top style='padding:.75pt .75pt .75pt .75pt'> "College and University Technicians" <caut@ptg.org> <o:p></o:p> </td> </tr> <tr> <td valign=top style='padding:.75pt .75pt .75pt .75pt'> cc<o:p></o:p> </td> <td valign=top style='padding:.75pt .75pt .75pt .75pt'> <o:p> </o:p> </td> </tr> <tr> <td valign=top style='padding:.75pt .75pt .75pt .75pt'> Subject<o:p></o:p> </td> <td valign=top style='padding:.75pt .75pt .75pt .75pt'> Re: [CAUT] Experiment success!<o:p></o:p> </td> </tr> </table> <o:p> </o:p> <table class=MsoNormalTable border=0 cellpadding=0> <tr> <td valign=top style='padding:.75pt .75pt .75pt .75pt'> <o:p> </o:p> </td> <td valign=top style='padding:.75pt .75pt .75pt .75pt'> <o:p> </o:p> </td> </tr> </table> <o:p></o:p> </td> </tr> </table> <tt>List,</tt> <tt>I think I read an article about Downy softener that said the long term</tt> <tt>effect wasn't good.
