Do you mean the grout haze?

Little bit of haze remover in the washboy water helps, wash off excess grout with cross cut sponge, then rinse sponge.

One wipe over in a verticle line, rinse sponge then repeat on next bit working across the wall / floor let it dry then buff it off with cloth, usually on old t shirt or t towel, thats dry and clean.
