Hey guys, what do you all use to clean the dial faces on the Mk5 GTi, I have seen a number for sale in dealers and on the web that have NASTY smudges and smears on the dial faces. I can see they have that pearly blue / purple coating and have never had a fingerprint on mine, however there are some rain spots I want to remove but don't know what product to use without damaging the coating or putting mucky fingerprints all over it - any suggestions ?
