I started on the top 3 clips, then the 2 sides. For the bottom clips I was able to stick my hand from the top while slightly bending the grill towards you and work your way from 1st clip towards the center of the bumper then work your way out. See the arrow in the picture regarding the 1st bottom clip (having a hook tool would make it easier since you know where clipping points are to apply pressure to release them):
