    Commercial grade bleach and a scrub brush on the end of a paint extension pole. It's going to take elbow grease, but once you've gotten it clean, reseal the grout with a grout sealer. Good luck.

    Clean it up good and rub white enamel paint into the grout lines.

    Use a solution of white vinegar and baking soda , a brush and lots of elbow grease.

    1. Make a paste.
    2. Apply the paste with a nylon bristled brush.
    3. Let the mixture sit on the grout for 15 minutes.
    4. Rinse the grout with warm or hot water to remove all of the solution.
    5. Use a rag to wipe the grout to remove any leftover residue or dirt.
    Mop the floor with clean water.

    Making a paste with OxyClean ans scrubbing works well too.

    Once it's clean, SEAL!

    I use Oxyclean on most all my cleaning, however I just discovered that even the store brands of "The Magic Eraser" works GREAT ! Cleans not only the soapy - mildewy scum but even the Rust that may accumulate and I agree that once you get it white again, seal it with a grout sealer.

    Make a paste of baking soda and peroxide then apply it to your grout with a toothbrush. Let it sit a little and then remove with a clean cloth.
