How to remove dark stains from laminate flooring

This is laminate flooring. Not planks. No idea what the stain is at all!

Any suggestions on how to get it out or what it is?

Response to answers below:
I have not tried steam cleaning. I heard water and laminate floors don't do well together?

Perfect wording Jack, I've been trying to explain this flooring for awhile, because it's not individual planks, it's all one piece, with a picture of wood on top. I do not know what the core is though.

It is mostly infront of the dish washer with a small dot over by the fridge and one dot to the side of the stove. There is also one near the trim on the wall which is no where near a water source (except the bathroom on the other side of the wall).

I have tried magic eraser in case it was a stain, and it did nothing. I have also tried acetone nail polish remover on a portion that was most hidden, and again nothing happened.

I live in apartments, and the manager had one of thier friends come "look" at it. He was saying it looked like I had split something which then stained the floor.(which doesn't make since for all the locations). I have been home while a whole dish washer cycle goes through and have not seen any sitting water. Would water even do this?
