Hello,
Sorry in advance for my ignorance. After moving in, I noticed that the floor has a “black tint” which I think because the moving company guys used their shoes.

I tried using some cleaning products that I bought from the supermarkt, but the tint didn´t go away. Any tips please?
Thank you very much in advance!
