Help with some floor stains

[DeSade]

We are doing a move-out clean and there are some large green stains on the vinyl floors
The floor is a rough (almost sandpaper) industrial vinyl and I suspect the green, is dye used in rodent poison or another ingredient. (one of the main reasons for moving)

Any idea how to tackle it?

Have used bleach and it goes some of the way but not all.

To get it perfect you would have to replace the vinyl.

Try some white spirits, or Brakleen (a CRC product), test first though because they may melt the vinyl.
