cant clean grout off porcelain tile

[Beckaj5]

Hi, I have just bought the infamous B & Q 60x60cm Porcelain tiles, yikes! How do I know whether or not they have this temporary wax that needs removing? What do people think of this sealant: Ultra Solv. I have read that its good. Also how many mls of this do you think you would need per sq metre?
Thanks
