Leave the grout to fully dry after a few days then try and clean with Mapei keranet with a 17inch rotary buffer, try white pads at first if they dont move it got to black ones ,

you have to impose. in these colored grouts.
It prohibited. and stop.

otherwise you needed to do a test.
Now problems .....
(I must not say. These things. You good you are !!!)
you have to try with special detergents.
other solutions. I do not know sorry

Thanks Gary,at the moment we stop,I grout just few tiles and now we wait the decision,too many architects,designers,project managers here in airport!Maybe if apply some good product before grout the problem is sorted but need wait...

Would test a suitable impregnator , but still may contaminate the face , worth testing on a spare tile first. , let it cure before grouting over it, as Gary ,let it harden , rotary and poss may need a cleaner
