Water damaged White under-finish stain removal tips?

428 Views 2 Replies 3 Participants Last post by  mark sr
I have multiple areas of white stains that appear to be under the Poly finish and I can’t get seem to find a good solution except for refinishing the floor.
Any advise to improve or remove the stains?

IF this is prefinished 3/4" hardwood, it appears wet boxes have been stacked on it and the moisture has eked down through the finish. I doubt it will be removable without refinishing the floor. How long has it dried? Sometimes over time, it clears up, but not often.
If time and dry air doesn't fix it I doubt there is anything other than refinishing that will remove the white spots.
