Laminate counter tops that are stained, but only when dry!?

I have brown laminate kitchen counter tops in my apartment. Somehow there is this whiteish stain on them in certain areas. When I wash them using anything, soapy water, soap, water, the stains go away. I look very closely and the stains are no where to be found. However, as soon as the liquid soap or water drys, the stains magically reappear! When the counter top is dry I run my hand over the stains and it feels like maybe the polish or protective layer as slightly come off where the stains are? Some one please help, I don't want to be hit with a huge bill when I leave my apartment. Please and thank you.
