White Grout gone blue

[Lukemac]

Hey guys and gals

I have just tiled a bathroom floor to ceiling(30m2) with granfix maxi white grout. The grout has dried and is a patchy blue and white!!! It looks horrible. some places are white some are a bluey colour. It is only the surface of the grout though, if I scratch away a bit of the blue it is white underneath. Does anyone no the cause of this??????

thanks in advance

Just what I was thinking Neale. I've turned White grout pink before with a red polishing cloth.
