Grout stains on the tiles?

[wonky1]

Good morning everyone,

I've recently tiled my kitchen floor, 22sq mtrs, and have just finished grouting. I cleaned up as much of the surface grout as I went along. However, after 4-5 washes on the floor and leaving it to dry overnight, I have a white residue on a lot of the tiles. I've tried washing them with some detergents and boiling water, but as soon as it dries- it's still there. :roll:

Can anyone help me and know how to remove this grout residue?

Many thanks in advance.
:)

most DIY shops sell tile/grout cleaner, I have tried one from homebase called ceramic tile cleaner, cleaning dark grey grout from buff coloured tiles and it worked a treat !
