Grout mould and mildew removal

Remove mold and mildew by cleaning with a dilute solution of chlorine bleach in water (one cup bleach to 3 cups water, increasing the bleach as necessary). Spray or sponge it on, wait a few minutes, then rinse well with clean water. Commercial mildew remover sprays can also be used. Be sure to wear rubber gloves and rinse the area well after cleaning.
