Tom,

You won't be able to fix that control with canned air because you need 
something that removes stuff that's attached to the contacts.  Pressurized 
air is good for blowing out loose dust, but that's not what happens inside 
volume controls.  The contact cleaner from RS is better than nothing, but 
it's not as good as some that I used to be able to get, but which is 
unfortunately no longer made.  I'm just catching up0 on email, so I haven't 
read the rest of this thread to see if anyone else knows of something better 
than what's available from the shack.

Steve
