What Is Grout Haze:

It's a semi-white haze left on the surface of tile after grouting. Even if you have diligently wiped down the surface with a wet sponge, haze will remain and will not come off until you take special measures; it will not come off through normal floor-cleaning methods.

What Causes Grout Haze:

Have you ever seen a ring on pool tile? These are residual minerals left after water has dried. It's much the same way with grout. Grout is made of minerals and cement mixed with water. When the water dries, minerals remains.

Residual grout haze is a normal part of tiling. Because grouting involves smearing grout across the tile with a rubber float, the tile is entirely covered with grout at some point.

Two Steps Before Using Haze Cleaner:

You want to physically pull off as much grout as possible with a rubber float and then with a sponge.

The rubber float is your best friend, because it's soft enough to drag the grout off but hard enough that its edge will not dig into your grouted seams. Use the edge of the rubber float to pull it towards you and off the tile.

Second, with a big tiling sponge--they are dense and about the size of a big paperback book--lightly dampen the sponge and wipe off remaining grout. Be careful not to dig into the seams.

Caution: at first, it seems like the wet sponge will take off the grout haze. But that is only because the surface of the tile is wet. As the tile dries, the haze will appear. Wet-sponge it again, let it dry--and more haze. The stuff is impossible to remove.

How to Use It:

Grout haze remover is widely available at any tile store, home improvement store, or hardware store, or online. Be careful not to confuse grout cleaner with grout haze cleaner. Two different things.

First, start cleaning after the grout has cured. If you try to clean prior to curing, you risk dislodging the grout and creating a mess whose only solution is to re-grout the tile. However, don't wait more than 10 days.

Clean the tile similar to the way you would wet-mop a floor, the only difference being that you'll be on your hands and knees with a sponge, rather than wielding a mop. Add about 3 oz. grout haze cleaner per 1 gallon of lukewarm water. Dampen the sponge and pull diagonally across the tile. Repeat as needed. Change out water/cleaner solution when water is murky.

Did you wait more than 10 days? Simply use the cleaner at full strength. If you encounter areas that have much haze, let the full-strength solution sit on the hazed areas for ten or fifteen minutes before wiping off.

Alternative, Organic Methods:

Some people recommend a solution of 1/2 cup white vinegar, 1/2 cup ammonia, 1 cup baking soda, and 2 quarts of water.

My take on the matter is that grout haze cleaner is cheap and you use it in small quantities. So just buy the actual grout haze cleaner and be done with it.
