Is anyone else getting this discoloration on the upper lip of the bumper fascia?

It doesn't seem to wash off or buff out, so thought I would ask around before getting more aggressive with it.

Just looks like lime scale to me? I'd see if the smaller spots will come up with a clay bar before using an aggressive descaler.

So far no joy removing this with CLR or a magic eraser.

What might I try next?

I would inspect it really closely to see if you can determine if it is something on the plastic, or if the plastic itself is changing color.

If the plastic is just turning white then no amount of cleaning will ever remove it (because there isn't anything to remove) and you may find something helpful here: https://www.rivianforums.com/forum/threads/keeping-black-plastic-trim-black.26071/

Thanks.

I have used a Ceracoat ceramic product on all of the cladding and it looks great.

This is actually the fascia just below the grill, which seems to be of a different material.
