Why the white haze is chemical
Rock salt is abrasive and scratches. The chloride salts are worse, because they are hygroscopic, meaning they pull moisture out of the air and hold it against the finish in a damp film.
Calcium chloride and magnesium chloride are the aggressive ones. They leave a white crystalline bloom, and if that film sits at a seam long enough the moisture gets into the wood underneath.

Where the damage lands, and how to undo it
The damage runs in a predictable pattern: the first six feet inside every exterior door, worst at the threshold, and concentrated where people stop to take boots off.
Fresh residue comes off with a neutral pH wood floor cleaner. Vinegar and water is the folk remedy and it is a bad one, because acid on a waterborne finish dulls it permanently.
Once the haze is etched into the coating rather than sitting on it, cleaning will not bring it back and the area needs a screen and recoat. If it has reached the wood there is grey staining and that means sanding.
The mat that prevents all of it
The failure is not the salt itself. It is the absence of a mat. A commercial-grade absorbent runner covering the first six feet of every entry, taken up and washed weekly through February, prevents essentially all of this.

Questions we get asked about ice melt damage to wood floors
How do I get white marks off my wood floor?
A neutral pH wood floor cleaner while the residue is fresh. Not vinegar, which etches a waterborne finish.
Does ice melt actually damage wood floors?
Yes. It scratches, and the chloride salts hold moisture against the finish and eventually get into the seams.
What is the best prevention?
An absorbent runner over the first six feet inside every door, washed weekly in winter.
