    I would not use that inside my house. Try Clorox spray bleach.

  • My vote is to not chance it. Swimming pool acid could make the grout crumble. Wiping down with vinegar will kill the mold spores. Then take a toothbrush and start brushing. Once you do get clean, I would seal the grout to make future cleaning easier.

    no too toxic and not good to use in a closed in space - I have seen folks using clorox toilet bowl cleaner on grout

    I would just replace the grout thats obviously had mould issues for awhile. Scrape it out and put new silicon caulk in and besure it says it has a mildewcide in it. Muriatic acid can permanently mar the tile and the tub.

    You cannot use pool cleaners inside.....Try cleaning them with a paste of baking soda and hydrogen peroxide.If it still dean not come clean ,you can paint the grout

    I would use a commercial mold removal product like TileX first. If that doesn't work, try a paste of peroxide and baking soda. Finally, use bleach. Be careful and use eye protection and open all of the windows for all of these methods.
