Challenger Pad Systems has developed a lightweight
brush for cleaning tile & grout. It attaches to the
existing pad driver on the Challenger via its own
velcro strips. In order to most effectively clean
down into the grout lines, the brush has 2 levels of bristles. The shorter ones work the tile surface,
while the longer ones scrub the grout. Price: $50 &
shipping. Contact me if you would like to order one.

To go the all-natural route, either just stay with
Outsolve, or try another Bioforce product, labelled
simply "Floor Cleaner". Home Depot also carries a
line (probably several lines) of products suitable
for scrubbing hard-surface floors. Theirs, of course,
would probably not be all-natural.
A slower, but possibly somewhat slower method of cleaning grout is with a steam vapor machine. I recently
replaced my aging $1100 Fogacci with a deLhongi, at
under $300, and it seems to clean grout just as well.
