There are some nice Bona finishing products available at stores like Bed Bath or online. Or you can get them professionally refinished for best results.
Victoria....a gloss floor is the hardest to maintain and "stay" glossy. every day soiling acts like fine sandpaper and degrades the shine over time. The best thing you can do is to keep it as clean as possible. When I finish floors I always recommend the "satin" sheen as it will look better over the long haul. A frequent "screen and recoat" will be your best bet to maintain the high gloss.
you can read about cleaning tips and finishes in this article I wrote.
Thanks for the answers, but I'm still hoping for more ideas.
A little vinegar in your water should make them shine.
Just make sure not to use too wet of a mop. You want them to dry quickly. Turn on a fan for a quick dry.

Then I found this recipe which mixes equal parts water, vinegar, and isopropyl alcohol, with a few drops of dish soap. Ahh, Eureka! The alcohol helps create that streak-free shine because it evaporates so quickly, and the dish soap gives it some extra grime-fighting oomph! After testing out a small area, I was in love. I proceeded to clean the ENTIRE house in one go – yep, that's how happy I was. I was so proud of my gleaming laminate floors, I literally couldn't stop smiling :) Even the hubby noticed how clean and shiny they were, and he never notices anything – so I took that as a huge compliment!
