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
Use an in home steam cleaner on it...
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.
