The tide may work well-when I was a kid I worked for a trucking company .
The boss used to have me wash all the trucks with buckets and a brush with tide and bleach.
Worked really well. We delivered bricks and concrete to construction sites in new York so the trucks were always filthy at the end of a week.
We do a lot of travertine floors up here-extraction makes it easy.
If you don't have portables hire a truck mount guy for the day.(if he can access)

Try using some Tide with Bleach...Scrub with a floor machine and work into a paste.
