FWIW I have never had any luck with cleaning the grey on my 1200N.
Maybe S100 will work?
(I have tried many other products, including most listed above, to no avail)
I can add, if you drop oil, wax or any fluid onto the grey color, remove it right away.
I also believe Harley sells a spray can of textured grey paint for a color match/ repaint if need be.
Good luck.

I was a Big Fan of S100, reg & gel, for years, should have bought stock in the German Co.! I have custom Sun Spoke Aluminum Wheels, everything stains them! Then I discovered Simple Green, my wheels shine, spray & rinse, I couldn't believe it, as Good, if not better than S100, for 1/10 the money!

I used to clean the cases on a BMW boxer with muratic acid. Absolutely nothing worked better. You have to be very careful. The acid must be thoroughly rinsed immediately after application or it will streak.
