The Bad news...
I have installed many Laminate floors, they are just a photo, with a very thin protective coating. Not much sanding allowed.
I will
call my flooring specialist if you want more of my help.

Well
no good news from the specialist. He and I discussed this problem. It is probably too late to recover.
FWIW, I have pushed my clients AWAY from laminate flooring for many reasons, since they first came out. Using the laminate flooring for WALL PANELING, is OK.
The flooring specialist (38 years) sent me to one of his major suppliers web site. I won't link it in this forum. I will tell you the YouTube "Do's and Don'ts" would drive me away from landlubber flooring even more.
The protective clear coat, may be Acrylic resin, if not Urethane.
His only suggestion was Vinegar, undiluted, and do circular motions with a damp cloth for the "foggy areas". The ideas is that that stain, might be "stubborn" type and
not an etching into the finish. Try at your own risk.
In you second picture, you can see the flooring delaminating all ready (upper left), which will expose the substate to possible water intrusion and swelling.
I am Surprised that more SBO'ers don't have similar problems or solutions!
The least costly method to protect our
non laminate flooring, which also serves as a work pad.....

We have 2, one for Galley and one for guest forward cabin floor. We use them to set large removable hatches, tools and doors during maintenance. Great floor and knee savers.
Sorry I didn't come bearing GOOD NEWS.
