Tools seem to be rapidly rusting

We just moved to a new location. I am now in a corner in large
workshop. I am not close to water or the pickle pot yet all of my
tools seem to be rapidly rusting. There is no more moisture in the
air then usual, but there is no ventilation either. The room is air
conditioned. The only thing I can guess is that maybe gas fumes are
staying in the corner and causing this. Any thoughts on this dilemma?
