Because they are non-polar compounds.  Water is a polar compound.  Since Oxygen is much more electronegative than H it gets a partial negative charge and H gets a partial positive charge.  This cannot interact with grease, which has almost no partial charge since it is non-polar.  Instead you need a non-polar compound, like dry cleaning fluids, to interact with and remove non-polar grease.
