I'm copying and pasting a post that I made a while back when someone asked about this issue.....
Okay, when we first moved in to our house, before moving the furniture in I cleaned the entire house (all Armstrong laminate with tile in the bathrooms) with a Swiffer wetjet. The next morning I come in ready to move in furniture and the floors looked awful! All streaky and dull! So I went out and bought a Hoover Hard floor cleaner which worked fairly well for a year or so until it broke. The floors were really never as streak-free as I would have like though using that machine. Then finally someone told me about Bona X. Here's a link to one I found just so you can see it but I get mine from my local hardware store. They make hardwood AND laminate stuff.
BONA X Premium Stone, Tile, & Laminate Floor Care System - BONA X Hard Surface Floor Care products.
I've had the same stick thing with microfiber pad for at least a year and it is still in perfect shape - wash the pad in the washing machine (with no fabric softener) and throw it in the dryer. The spray goes a long way too.
Just last week my mom emailed me and said that two ladies she works with were talking about how they couldn't get their laminate floors streak-free so she asked me what I use and passed it on to them. One of them called her office phone to leave her a message at 10:00 that night SO excited because she had gone out and bought it that evening and was so impressed. The true test for me is that one side of my house is almost all windows and in the afternoon the floor is very much on display..... not a streak to be seen!
I hope everyone with laminate floors will find this product as wonderful as I have!
Seems there are other products out there that are very similar but I think the most important part is the microfiber pad!
