Doesn't the white film mean acid was left over (not enough pressure washing) and that would keep stuff from adhering to it? I also wonder if one can fix it if it did dry and some wasn't washed enough. I figure if there are some areas that seem not to have been washed enough, one could grind that off to clean it off.

thank you for this information
Did you end up using 100% concentration? I noticed if I don’t dilute the solution it works better.
Yes I did use 100% concentrate.
It appears like a dusty film, but it’s not. It doesn’t come off on your hands or anything.
Too much work
