Was washing my C350 when I noticed.....
There are discolorations in the paint running down from the rear license plate. It looks like soap residue, but no amount of scrubbing & rinsing will remove it.
Could this be from salty water running down from the license plate over the winter?
Any ideas on a solution? A polishing compound perhaps?
Thanks.
(Hard to see in the pic......too much sun right now.)

Here's a few more pics. It's hard to get the camera to pick up the discoloration. In the angled pic you can see how underneath the license plate the paint is dulled (foggy), but shiny (normal) beside to the plate.
As for paintwork cleanser, do you have any specific suggestions? I know little of such things........
Thanks

Yes, it really is hard to tell from your pictures. Paint cleansers of Klasse All In One (KAIO) or P21S should be a good first try. I know for a fact that the P21S is fairly easy to work with the hand, if you do not have a machine.

yes I use it by hand, but I can't compare to P21s ( never used it )
here's some results I got

here is another Pro-detailer's results

so IMHO, the OP will be happier with werkstat prime strong than other cleanser on the martket.

It turns out that when I removed my plate there was some calcium/lime build-up crusted on the back. I do live in the middle of nowhere and there's a lot of rock so perhaps there is a high mineral content in my water.
I assume this caused the problem because the fogging of the clear coat appeared like drip marks directly beneath the plate and nowhere else on the car.
I ended up using Maguiar's Ultimate Compound (none of anyone's suggestions were available in my small town). A little dab and some elbow grease brought back the shine. I also used CLR on the plate to remove the calcium/lime build-up. Hopefully, this doesn't become a recurrent problem......otherwise I may have to start taking my car to the big city for washing.
Thanks everyone.

In detailing, if available, you always want to start with the least abbrasive product, therefore our recommendations at first.
Enjoy your results
