How to clean/restore my tiles?

[Melo81]

Hello!
Any advise on how to effectively clean tile’s stains?
I have a 16 gl Salt pool. Stains are only present i the tiles around the spillover area (rocks).
Hopefully you can see my attached pics.

Thank you in advance!

Try this with a lot of "elbow grease." Get the large size.
