Calcium Chloride Corrosive Effects

I know that calcium chloride can corrode metal, but does it require direct contact or can it generate fumes that could corrode?  

Here's the issue:  I have a wood stove and I place a container of Damp Rid inside over the summer to absorb moisture.  It looks like the Damp Rid plastic container had a small crack, so moisture passed through the calcium chloride and through the container and through the back of the stove After a while I noticed a pool of water behind the stove.  I traced the problem back to the Damp Rid container, cleaned up the moisture inside and outside the stove, and replaced the Damp Rid.  At the same time I noticed areas all over the exterior of the stove where the finish was coming off, areas that were not in contact with the water.  In fact, at least one section of the stove that had direct contact shows no sign of  a problem.

I'm trying to discover if the calcium chloride caused the problem, or if it's something else causing the damage.

.  CaCl2 solution (it is very hygroscopic, so it absorbs water from the surrounding air) doesn't vaporize easily at room temperature but it does "creep" into all sorts of small cracks, crevasses, &c. Unless you can come up with another suspect, I'd assume the CaCl2 caused the problem.
