We have a pine floor (not recommended, too soft.) It's finished with a
typical polyurethane (I assume). The problem is the color is changing under
a rug. We had one in the kitchen, and it was lighter under the rug. I
owuld have thought it would be lighter where the sun was bleaching the
floor, but the opposite was true. It's not a case of the floor being dirty,
it's cleaned regularly. Now I have to look under the living room rug. I
haven't been able to get it all the way back but I haven' been able to tell
if it's been discolored yet too. Any ideas on what's going on and if
there's anything to do other than take away the rugs? Is the kitchen area
permanently damaged if it comes time to sell the house? It's not horrible,
but I think many people would notice if they glanced toward the floor.
