Best Answer

Concrete is usually alkaline and porous. Thus it may be attacked by acids - even mild ones such as milk!

The porosity means that materials such as motor oil will be absorbed.

Sealing the surface with an impermeable coating will help in avoiding these problems. This approach will work even better if the concrete surface has been made more dense and smooth by surface working before it has set.
