Don't ever use mop and go type cleaners on your laminate floor. They build up a dull residue with time. Don't use any wax on your floor -- this doesn't work for Laminate. Pergo makes a spray cleaner (hard surface cleaner) that is perfect for cleaning your floor. Mohawk and Armstrong also make comparable products. I have also had a lot of success with an Orange-Glow product in a spray bottle that I get at Target. DO NOT USE the resurfacer in this line -- it is only good for hardwood floors. The cleaner is perfect and comes with a special mop that shines the laminate really nicely.
I know Zep hardwood and laminate floor cleaner will help bring back a shine. it sold at Home Depot. mist it on leave it for 5mins then wipe it off
