I have a permanent pee spot on the far side of my dining room table, on the laminate flooring

I didn't see it until it was dried up, so it must have been there for a while

It won't go away

Unfortunately, the damage is done once any liquid has been allowed to sit for too long
When I can afford it, I'm having REAL wood floors installed. At least they can be refinished if something happens.
Good luck to you
