Most likely there is some kind of cheap wax on it. It needs to be removed and restored.
You need to buy some LamanatorPlus Deep Scrub and Restoration. They actually have a do-it-yourself kit that has everything you need to restore laminate. It includes the Deep Scrub, Restoration, Buff Dry Maintenance Product and a mop kit with handle and a DVD instructional video. Awesome and easy to use...it will work on that floor...
You can find them on the internet at
