My '05 TSX has Eony interior. Anyways, soon after I got it I started to notice a white, powdery like spot starting to appear on my drivers door panel (on the upper portion) I cleaned it and it went away. Then it re-appeared again and grew by the day until I cleaned it off again. This is a weird deal, I mean I clean it and a few days later it's back. It starts off small, and if left unattended it grows in size. I thought that maybe I was accidentally resting my arm for too long, but I have been supervising myslef and I am not. Anyone have an idea of what this might be?

I notice that my ebony also gets white powdery marks...but I'm pretty sure its from contact with our skin. I wipe it off with a dry towel and its gone. I never noticed it growing in size???
