Measure out 3 cups of baking soda, and pour it into a bowl. Combine this with 1 cup of warm water. Mix the two together until a paste forms.
Use your fingers or a putty knife to apply the paste to the grout. Be thorough, and work it into all the cracks. Spread the paste in small sections at a time. Clean the grout in one section before moving onto another section.
Use an old toothbrush, and scrub the grout with the paste. Add more paste to the grout as needed.
For badly stained areas, spray tile cleaner onto the grout. Allow it to soak for several minutes into the grout before scrubbing the area.
Rinse the baking soda paste and tile cleaner from the grout using clean water and a rag or sponge.
Dry the water from the grout with a towel to keep the tiles free of water spots.
