I have this really irritating problem.

White spots/marks keep re-appearing on my black slate kitchen flooring. It usually looks ok after mopping/when wet, but when it dries up, the white spots keep re-appearing.

Any advise on how to solve this problem?

You can try touch up using black paint marker and apply a layer of thin lacquer over it.

You can clean with good cleaner.
