I was once the guy who thought there had to be a product that would clean faster and better. I can't tell you how many things I ruined when I was growing up. (How do you think I knew that you were in a rush?)
So please don't think of yourself as a dummy. It's all in the recovery.
Learn to do what the rest of us do when visitors come over, bring them over to the tile, and with a big smile say, Isn't this haze Great! I was not sure if I could really do it! It was not as hard as I thought it would be!
That should get you off the hook with your remodeling skills. Of course your taste me be questionable after that but, I could live with that!
Keep on trying and we will try to be here to lift your spirits.
