How to clean concrete stains!

Well as you all may be well aware of, working on your car, makes messes, stains floors! I personally don't care to much but my land lord threw a fit when he saw some of my floor lol

So he want it cleaned up! Heres what I have... Garage floor is concrete and the backyard has concrete pavers. The stains I have on there are, transmission fluid, pb blaster, grease, just car gunk/grease/grime stuff that fell of suspension and other parts of the drivetrain during removal. Heres the big one! I got a bucket and filled it with white vinegar to drop some suspension parts in, well after about a week it turned kinda orange and I took it out into the backyard and took out the parts layed them on the floor and sprayed them with my pressure washer. Left that orange tint residue on the floor, and that the one I cant remove!

I have tried the simple green purple heavy duty cleaner, the purple power cleaner, I do have some of that kitty litter oil stuff, not sure if Im using it right because it doesnt exactly make it look like nothing was ever there, and thats if it even lifts some of the stain, dawn liquid soap.

Any recommendation on how to clean this stuff? A wire brush will work but it leaves it looking whiteish like its just removing some of the concrete.
