Alexandra,
 
It has been my experience that the fog/smoke machines that use "smoke
fluid" tend to deposit an oily residue on surface.  It has been a while
since I used one though, so technology might have improved.  Dry ice or
some other technology may do the trick.

Subject: [MUSEUM-L] smoke screens in museums
 
And another question...
 
I am looking for thoughts by conservation and collections staff on the
use of fog machines or smoke screens in exhibits. The Indiana Historical
Society has launched a new exhibit that uses a sensor-activated smoke
screen, projecting an image on a wall. The director of conservation and
I are monitoring the changes in RH in the galleries and are interested
in how other museums and galleries have found compromises between
exhibits and conservation regarding this technology.
 
Any insight would be much appreciated. 
 
Thank you again,
 
Alexandra
