My laminate floor has been so dull looking. I have been using the Bona cleaning system for laminate floors. I finally emailed their CS and told them they need to replace my floor; they called back. She asked me to do a couple things, first take off the sprayer on the bottle and tell her the color of the liquid(it was blue), then read her the numbers on the back of the bottle, and finally spray it directly on a mirror and do not wipe it off with a papertowel but let it dry. It left a lot of residue. She then told me that perhaps the solution was old and "breaking down". It shouldn't cloud up the mirror. She said she would send me a new bottle. In the meantime, she told me to clean my floors using a solution of half apple cider vinegar and half water and spray it on and mop with the microfiber mop. I had used vinegar before but never half and half. Anyway, I cleaned my floor 5 times! That's how much residue had been dulling the floor from the Bona. Then I used the white dust mop in that system and buffed the floors. They now look like new.
Today I received a gallon bottle of Bona cleaner but at this point I may not use it at all. I like the vinegar solution better. But it was a lot of work to clean and buff the floor. I also read online a tip from Bob Vila who said to add a couple drops of baby oil to your vinegar solution while mopping to add shine. I'll try that next time.
