I bought a Nikon N90s that seems to be in nice shape, except it stinks of cigarette smoke. Out of the packaging, the stink was obvious, but I have managed to lessen it with some cleaning. The cleaning has been more effective on the exterior, as I can do only so much with the interior, but I have at least lessened the smell on the inside, too. In any case, is cigarette smoke damaging to cameras? I have some time left to return the camera, if necessary. Also, does anyone have any further advice on cleaning? I have used mostly alcohol and vinegar thus far.
