That was post washing with soap and water. It looked much improved, however if you look in the second pic you can see little black spots/pits where I imagine debris has peppered the grille (mostly on the lower portions). Also, it appeared to me that the spots became more prominent by using the grey compound. It was as if the little pits were filled in with compound.

So...I decide that perhaps I should scrub ther grille at this point with a mild abrasive. I used Bar Keepers Friend, which is used to clean stainless, and a sponge and cleaned up the whole grille with small circular motions. Doing this actually created a kind of brushed aluminum look and effectively diminished the appearance of the tiny pitting.

In the first pic, in order to show the difference pre and post scrub, I left one portion of the grille unscrubbed. I think the difference it is fairly clear in the pic.
