How can I change the grout colour of my ceramic floor tiles Help, advice, information, answers and tips on all types of flooring from laminate and carpet to timber and vinyl

When I laid my ceramic floor tiles in the kitchen, I used a white grout. Big mistake as its always dirty. Not sure if I should have sealed it. Is there an easy way of dying it black/dark grey as to remove the grout would not be an easy task!
