unsightly grout

we had a mildew/mold issue with parts of our bathroom shower grout. My wife has tried:
10% chlorine bleach with 90% water
Vinegar and water 50/50
1/2 cup baking soda 1/4 cup hydrogen peroxide
At this point she feels the mildew/mold is gone but the grout is just stained and she can't seem to get it out

Any suggestions?

I'd try a stronger bleach solution - maybe 30-40% bleach [assuming it's not a dark grout]
Sometimes it's best to use a grout saw to remove the top portion of the grout and then re grout.

Unless the grout is white, I would limit the use of bleach. They have some enzymatic grout cleaners, but if the grout is heavily stained. re-grouting and then sealing may be needed.
