I'm a newbie that's just bought an '07 A3 Sportback, which has got the silver roof rails.
The problem is that they look waterstained and sort of flat and patchy. I gave one of them a quick polish with some Zymol I had in the garage, but it didn't really do much. I also asked at Audi and they said they didn't have anything special to clean them with.
Does anyone know if these are lacquered or anything? I've got some Autosol metal polish, but I haven't been brave enough to use it in case I ruin them.
Is there anything safe I can use to get these looking less patchy. I'm not even sure if they should be shiny or a more dull aluminium finish. The last photo below shows the end I gave a quick polish with the Zymol.
Any advice would be gratefully received.
Hopefully you can see what I mean from these pics:
