On advice from some other members I ordered some Billbury wheel cleaner to help clean the wheels on my S-line. Valet PRO Bilberry Wheel Cleaner 5L - Buy online from i4detailing.co.uk It arrived today.... sort of..... Royal Mail are clearly employing elephants in their sorting offices, because despite the bottle being packed inside a SEALED plastic bag, then cushioned in lots of polystyrene foam, and then placed in a cardboard box, they managed to handle the box so badly that everything exploded. It looked like something out of a horror movie, or some forensic evidence bag - I wasn't entirely sure which bit of body I was going to find in the box.... Anyway, once I'd wiped the blood off the bottle and examined the instructions it says 'Not suitable for un-laquered polished rims' - my question is: Is this ok to use on the S-line wheels? It was my understanding that they are polished rather than fully painted / laquered. In the mean time i'm waiting for a replacement bottle!
