My feet turn black on the bottom from this floor, is there a black film on it that will go away?

Have you tried the Laminate and Stone cleaner from Bona? It is sold in Lowe's and has been very popular. It sounds like there is a film being left on the laminate. I have not heard of this before.

I haven't heard of any problems like that with this floor. I would highly recommend bringing in a scrap piece to your local specialist and having them take a look at it. From your description, I have no idea what the problem could be.
