Don't whatever you do try bleach to clean the grout on marble tiles.
What's the issue?
I ask, because years ago, I had superb results using bleach to clean a Carrera marble overmantle* that had blue fountain pen ink spilled on it (someone knocked the bottle over on top!). The ink sank into the marble.
It is 30+ years ago, but IIRC, I made a pond using Plasticine and let a film of bleach sit on it for a few days - I didn't use very much, and I did test it first out of sight. I don't remember attempting to actually neutralise it, but just washing it off well afterwards. There was no damage from the bleach, and the piece was professionally polished afterwards: it came up beautifully.
But marble and acid - no way!

*I think it really was Carrera - it was an early Victorian overmantle and worth a tricky restoration as it looked gorgeous when it was done. Someone had also fixed a double socket box to the front surface of one pillar, using Rawlplugs to hold the screws!.
