A lot fo the result will depend upon the surface of the conrete. Some is much more porous than other. If the stain is deep in the concrete, it obviously will be much harder to remove no matter what cleaning agent you use.
Acid cleaners work by removing a thin top layer of the concrete. This may be alright if you want a rough surface, but it can mess up slick finished concrete. I would stick with the alkaline degreasers.
