Hi I've just laid 26m2 of wood effect polished porcelain tiles (quite high end from Italy. Fioronese urban wood)
After laying them I cleaned then with ltp grimex to remove factory wax, then sealed using ltp sealer impregnator left for 20 mins then buffed them up. I left them for 24 hrs to cure then grouted in black (nightmare I know) then I washed them off then polished only to find that the grout had stained the tiles.

My question is is there a realistic way of removing these stains. My feeling is no but if anyone out there can advise I would greatly appreciate it.
I just can't see where I went wrong. I'm totally gutted.

I would start off with a porcelain specific cement residue remover, testvonly 1-2 tiles in a descreet area. dilute 1-3 or as stated, pre wet your joints, ( you don't want to burn your black grout joints grey) flash clean 1-2 min with brush or white pad. Rinse , dry , re test a stronger dilution if req.

What make of grout is it.?

Did they advise to remove the wax first? This could have protected you

Shot in the dark but I had some cheap ceramic white tiles stain when I used Bal Ash grout. The staining was on every tile and no cleaning product could sort it. Bal Technical had no idea. I crapped my pants if I am honest as i would have had to pay for them to be replaced.

The only thing that worked an absolute treat were Flash Magic Sponges. Saved my bacon. Had to raid the local asda but they were well worth it.
I always keep a few boxes in the van just incase.
