They have enough pressure to move the dust off a soundboard, but I wonder if there would be any negative effects to the strings.  Gas aside, it comes out at a very low temperature.  (Warnings on the label state that you can get frostbite if directed directly at skin.)  I suppose there could be condensation on the strings that might precipitate rusting?  </DIV> <DIV> </DIV> <DIV>The easy answer is don't use it to avoid any problems, but boy, it would make cleaning a soundboard a breeze.  Anyone ever tried it?</DIV> <DIV> </DIV> <DIV>Tom Sivak</DIV> <DIV>Chicago</DIV></BLOCKQUOTE></BODY>
