My best guess is that the poly wore off and water sat on the wood too long
before it was cleaned up (read icemaker and refrigerated water in front of
the refrigerator). So the wood is rougher and darker at two pkaces on the
floor. Sorry I was not more explicit in the OP.

If moisture has stained the wood, how will lightly sanding the
finish
get rid of the stain in the wood itself?

The OP said discolored. From the original post: "These are in front
of the
refrigerator and the door where obviously
moisture has set and discolored the floor."

It could be surface discoloration of the finish itself. Do you know
for
certain the the water penetrated the finish and stained the wood?

If it is the finish only (most of these are pretty durable) lightly
sanding
will cure the problem.

Hey Ed. The OP did write discolored in the body, but the subject line
is "Stained wooden floor". So I guess we're both interpreting it in
different ways.

I've never seen a polyurethaned floor where the poly itself was stained
from moisture. Seems to me that the poly, once cured, is a moisture
barrier and won't absor water - otherwise, what's the point? I guess
the OP will have to chime in and let us know exactly what he means.
