In our laboratory, we have also experienced this, especially with
microtomes.  As Jennifer has said, it seemed decal solution containing RDO
was the culprit, when used in proximity to microtomes.  Techs who used RDO
for surface decalcification had more rusting on exposed metal parts of the
microtome, probably due to incomplete rinsing of the block after immersion
in the RDO.  Parts of the microtomes not exposed, where the acid seems to
have been penetrated, included locking mechanisms and under the blade
clamp.  I would suggest anyone using RDO surface decal do so by immersing
the block in a shallow dish of RDO (square Coplin jar lid works well).  We
now store RDO away from the microtomes.

We have no data on how the techs may have been rusting as well.  Effects
may rival fixation of techs by close proximity to formalin x years. It's
Friday :)
