When we first moved in to our house, I used the Swiffer Spray Wet Mop for hardwood floors in the office (pictured below). I have very shiny glossy finished floors. The Swiffer cleaner literally took the gloss off the floors in those two rooms. I was devastated and didn't use that cleaner again. A friend of the family (who owns a flooring company) suggested we try Bona Hardwood Floor Cleaner, and I bought the high gloss polish to try as well. My husband I went out and bought some today and did this room a few hours ago. I am so please and excited to say that those products have fixed the mess that the other cheaper cleaner did and I thought ruined my floor. This is the after picture and I will never ever use any other products again. For 8 months I have tried other products and thought my beautiful floors were ruined! My beautiful glossy finish is back! Bona products are the way to go!!
