I would like to clean up.

The floor is only a few years old, and has a very nice troweled surface.
So, I don't want to use anything that will etch or damage the concrete. I
just want to clean up the stains and dirt.

Any recommendations other than the basic soap and water?

Thanks,

Not for everyone- heat the oils spots with a propane torch.
Not too hot or it'll flake off, sometimes with quite a pop!

Really not for everyone- soak the spots with flammable solvent for a
while, when it has wicked down add more, add a bit more and light that
sucker up. It won't get hot enough to spall the concrete, but it will
get hot enough to wick the oil-solvent mix up from a little below the
surface, and it'll burn right off.

Apply these methods at your own, um, risk!
