[O.P. posted:]

I'm a do-it-yourself newbie who's trying to clean the stained grout
(used to be white) between the tiles over the bathtub in my
bathroom.

The stains appear to be a combination of soap scum and rust stain.

I've tried several products that claim to be "grout cleaners," but
they haven't worked.

Is there any alternative at this point to stripping all the grout
and regrouting (quite a long job)?

Even some way of staining the grout white again?

*Comet or Ajax cleanser with a toothbrush. The bleach in the cleansers help
with the whitening.

Amen to that. Exactly the ingredients I was going to suggest: abrasive
cleanser and elbow grease.
