hi -
I use the pergo cleaner (found at home depot) or water/vinegar. To avoid streaks, use a towel to dry the floor after mopping (like you are "buffing" the floors). For best results, use a microfiber mop.
other tips I found on the web:
• In order to prevent a film from developing on your Pergo floor, nothing works better than straight water.
• Do not leave water on your Pergo floor as this will cause your floor to swell.
• Never use soap or detergents, wax or polish, as these products will leave a film.
* "The vinegar and water solution in a spray bottle misted on and use a dust mop type "mop " to go over it. Or they sell special laminate cleaner that won t streak. Use the same swivel headed dust mop to go over it with. Laminates dont shine , they are made in a matte type finish as to be slip resistant. Some have a satin or slight shine but not shiny."
hope that helps!!
