I have just re grouted an area in my kitchen. It looks good BUT the area near the taps keeps getting wet and looks much darker. Should I be doing something extra to keep the grout white in this area? Rest of the grouting looks fine, presumably because it is dry.

You should get it dry and use a grout sealer this will keep it looking white and won't discolor you may have to apply a couple of coats
