How to remove this type of "stain" (picture included)

[nokidding]

Hi,
I was wondering if anyone could help me with how to remove this darkening on the tiles? I have tried bleach, Vinegar + Baking Soda , Grout cleaner, mold cleaner , stone cleaner (all with scrubbing) with literally minor to no impact at all. Big thanks to any suggestions.

I'm leaning towards stone (I'm just there to clean that area not a tiler of any sort), the tile is fairly rough when you touch it by hand.

Sadly no they were there before I was employed at the place but I have a feeling that it occurs in places on the stairs where more water sits in a small puddle when it rains. They just appear randomly at different places (stay permanently) while the rest of the stair tiles are clean without them. I'm not sure if it's a "stain" (was not sure what else to put in title) as in something was dropped, it could have just appeared cause of possible other reasons cause it's on random different places/tiles.

It is dirty water staining that sits on the tile and not walked off by foot traffic.

Try using a white Scotch-Brite pad or similar. If this cleans up, try and source a tile impregnator/sealer to help keep the tiles clean.

Thank you I will try this as soon as possible and let you know, do you recommend any type of cleaner (e.g vinegar) to do it with?

Would a similar alkaline product be ok? I'm not in the UK and it would be hard for me to get, for example something like Tricleanium 1kg All Purpose All Purpose - https://www.bunnings.com.au/tricleanium-1kg-all-purpose-all-purpose_p1670019

By the way thanks everyone who took the time to respond.

Hey guy I'm solved the issue someone on another forum suggested professional strength brick and tile cleaner (i used a similar product from the same company which did not work but this one did) which i got and scrubbed with a steel wire brush and it got rid of the stains.

Thanks all who replied
