    If the dark stains are from black mold you must scrub the grout with a mildew remover. first. Vinegar and an old toothbrush work well. After the grout is dry , give it a day to dry out, you can buy grout paint. I comes in a small can. you paint the grout with a brush and as you work you wipe off the grout paint from the tile with a damp rag as you go.

    Everytime I get out of the shower, I spray my tile/grout with a mixture of half n half vinegar and water.

    Now if your grout is looking dingy, spray with the mixture of vinegar and water, and let sit for about 5 minutes. Then you scrub the grout with a scrub brush or toothbrush. Rinse with warm water.

    Next, in a small bowl, you are going to make a paste using some baking soda and water.

    Then you dip your toothbrush or scrub brush into the paste and work it into the grout.

    Then you spray the area with your vinegar/ water solution. The vinegar will cause the baking soda to bubble up and will start to work away that nasty soap scum. Use your brush and get all the way into the grout lines to remove buildup. Rinse with warm water.

    I don't know if you have mold or mildew, but if you do, try using Hydrogen Peroxide. Spray some on and let it stand for about 5 minutes. Then rinse with warm water.
