Something new about floor cleaning

I just bought a bottle of Rejuvenate. I read all of the things of how to prepare the floor. I still felt I was missing something. So I called the company and got customer service. Boy did I get a ear full. They told one of the reasons the floor dulls is the things I had used to clean. hey told me to use only 409, fantasik and would you beleave this ( blue dawn) it removes all scume left on the floor. So today I spent steaming my floor, then tomarrow wash it with dawn then rinse it. This sealer taked a hour to dry. I will try and take pics if it works.
