I had the foundation repaired in my basement a while back and the dust from the cement is still there, I've washed the floor about 5 times since and it still hasn't come off, got any suggestions about what I should do?
You should flush the roof and all side walls.
The cement is doing what it should. A previous questioner had trouble with the concrete floor in his garage. He spilt some vinegar on the floor and found it had eaten the surface the next day. If you can convince your wife to let you have some for an experiment ??? Beware vinyl stained by vinegar and swapping one problem for another. GL>
