Dampen a sponge with water. Scrub the area to work the baking soda into the stains like a scouring powder. Rinse the baking soda and vinegar off the tile with clean water. If water spots remain, repeat the process. When the tile is clean, dry it with a towel to prevent minerals in the rinse water from leaving new spots.
Lay out the tiles: After you've found the center point and squared the room for floor installations (or determined the top line level for walls), lay the tiles out to see how they will appear. Do it dry, before you mix the adhesive or mortar, within each quadrant of the grid.
