Get rid of mold on travertine

My shower is travertine and I have a serious mold problem. The grout is affected too. There may be water behind the tile so hoping not to have retile to solve the problem. Help!

    The grout may not have been sealed. You will need to allow the shower to dry completely for a minimum of 48 hours. Dry scrub the mold (wear a mask), no water, and remove as much as possible. Use a paste of baking soda and water and leave for 24 hours. Dry remove with a brush (don't use water) then scrub with hydrogen peroxide. Let dry for 24 hours. If the mold is still not removed, you will need to remove the tiles to see what the problem is behind. If the mold is removed, seal the grout and the travertine with a stone sealer. Let completely dry.

    Try Clorox spray cleaner with bleach.
