Concrete slab cleaning

asop

It's an interior slab aprox. 2,000 sq. ft.  that has alot of oil  staining.  I have an electric heavy duty floor scrubber.  Scrubber discs are about 2' in diameter.  One disc has "steel bristles" & the other has heavy duty "synthetic type bristles".  Any suggestions as to the "cleaning product" I should use would be appreciated.  Thanks

Charlie-Ya, viewed that and maybe 6 others.  Many options out there! Looking for someone that maybe has some experience with this.  Thanks

Outside I've used muratic acid inside I've never done.

I think solvents drive the oil deeper.  The "oil eater bugs" is what I would try.

The problem is, unless the concrete has been sealed, a lot of the stains have probably penetrated a good ways into the concrete. You can clean it so that it looks great today, and then in the morning the stains are back because they worked their way up. I had this problem with an old garage floor that a lot of oil had dripped on. After several days of cleaning, I finally sealed the worst of the oil stained areas with shellac then coated the entire floor with epoxy floor paint. Worked great and still looks new.

I wonder how the solvent cleaner Spray NIne would work?  It works great on everything else I tried it on.  Its one of the best Ive ever used.  Kinda like the WD40 of cleaners.  It even works great on carpet spots.
