As the title suggests , the raw alloy is starting to stain on my wheels . I know of most of the alloy cleaning products available , but what have those that have  these rims used to clean the raw alloy outside rim and spoke accents ?

Eagle One Never Dull wadding polish.  The old wadding polish in a can. Has been around as long as I remeber but under a few different names. Picked this can up a couple of years ago.  Takes about 3 stubbies per wheel with a bit of elbow grease but just do it about twice a year. Bike stand,old office chair and a six pack. done.

Was at dealer today and they confirmed no clear coat . So alloy polish it is .

Problem solved mate?

Well done Lofty , they look great mate .
