[vw754]

I grouted my kitchen floor tiles , but I have some dried grout left on the surface of some tiles ,now when the Mrs mops the floor the edges of the tiles look dirty as the grout has thinly dried , makes the tiles look as if there dirty , even tried using Brillo !......still won't shift it.....any more help please?

It's extremely difficult because grout dries like cement.

Posting some pics might help with suggestions.

You can try some ‘Grout remover/cleaner’ from any of the tile shops. This is in effect a very mild etch, so be sure to wear gloves. If first attempt doesn’t work, then change the concentration for the second attempt.

Assuming they are Porcelain tiles, another way, though much slower, is just to scrape it away with a brand new Stanley blade.

It's that thin I can't scrape it , I have tried , it just looks like dirt but it's definitely grout , will try the cleaner , if that doesn't work someone suggested cement remover

I think it’s much the same stuff, just in different bottles

If the tile surface is uneven, it's not going to be at all easy.

You might consider using paint to camouflage the grout, although how easy this would be I'm not sure.

Those tiles are notoriously hard to clean. ( if not done at time of grouting )
It'll definately need to be one of the etch treatments as above.
Don't even consider putting paint on them !

On reflection, attempting to use paint would be exceedingly difficult to get right, as you wouldn't be able to get the right reflective quality, so I wouldn't.

It doesn't actually look that bad to me, and maybe natural wear over time will improve it.
