Once you've identified the center and baseline from which you will work, snap a pair of perpendicular chalk lines. These will divide the room into roughly equal quadrants. You'll want to work outward from the center point in each of the four sections.
How to Remove Water Spots From Ceramic Tile: As hard water dries on your ceramic tile, it leaves a film or buildup of minerals behind. Harsh cleaners or scouring substances can scratch or scuff ceramic tile, but mild household items can dissolve water spots without damaging the surface. The acid content of vinegar breaks up the alkaline mineral deposits, and the gentle scouring properties of baking soda help remove the water stains and any soap scum to leave your tiles sparkly clean. The longer that water spots remain on your tile, the harder they can become to remove, so tackle them as soon as you notice them.
