I purchased a brand new house with engineered wood flooring and I thought I was doing a prudent thing by using the "best polish available" to protect these beautiful cherry floors. I used the Bona High Gloss polish and it looked good for about 30 days when it started to show every foot, hand, and dog print After 60 days it started to get hazy and has only gotten worse ever since. We've used bona cleaner and tried touching up the polish with no success. Giving up on Bona I have ordered several bottles of the Polish Remover and spent days hand scrubbing the polish off and using a floor buffer, but it barely takes it off and all a buffer does does is push it around. Now we have to hire a professional to come fix this problem.
