Non-polished marble floors - Tile Advice

[IE00]

Hello, our cleaner used something on our floor, we are not sure what, could be an acid cleaner or bleach cleaner. It's caused an etching on the tiles. I've seen forum responses for restoring polished marble, but what do we do with non-polished marble to restore it? Photo attached.

Also just confirmed that it was a bleaching product that dripped from the grouting into the floor. The stain goes away when wet but returns when dried out. Any ideas of how to fix it?

Hey
If the stain goes when wet, you could try a sealing product. test it on a single tile. If good seal the whole floor.

Thanks, I already tried an impregnating sealing product and the stain reduced but didn't go aeay. Which one would you recommend?

Hi
Any of the sealants should have worked, but if you have already tried one and it didn't solve your problem then it sounds like the damage is not repairable.
It is really a matter of experimenting with different products to see which one gives the best result. If it was damage from bleach it will be difficult to remove.
You say it goes when the tiles are wet? It might be worth trying treating a small area with a Danish oil rather than a sealant.
