Smartening up a shower

[ChrisR]

Customer has I think marble tiles. A cleaning person used something too acidic which has taken the surface dull. You can see in the pic the whitish runs coming off the shower mixer.
Is there some sort of paste/polish treatment, probably with a machine, which can be used to get them smart again? Something like T-Cut on cars!

Secondly, the waste is horrible. It's the wrong type, in that it's a McAlpine one designed for sheet floor covering, but it's working, and apparently not leaking, probably due to the liberally glooped-on silicone.
Without removing it from the floor, which would be difficult because of the plumbing, does anyone have suggestions for again, smartening it up?
Do the parts from the "correct" tile-waste fitting fit the centre part - I think it's stainless??

I wondered about getting a disc of satin stainless cit with holes at the right fixing centres, not exactly trivial though.
The pics might be a bit large..:

hi,1st off were the tiles sealed by the tiler after installation,if not wipe down with a dry cloth to remove the residue,then get the right tile sealant to suit that type of tiles as there are many different types of sealants.seal the tiles twice.i use a small roller to put sealants on,then wipe off any residue after it has dried.
if the tiles were sealed by the tiler after installation,then they probably need a restorer putting on them and then a sealant,matt or glossy your choice.hope this helps. see your local tile shop specialist.
