Hi all - use my zed all year round and seem to spend ages each week trying to get my csl’s clean . Dont know whether its the style of the wheels but they seem to collect loads of road grime in the corners where the spoke meets the rim. Have tried a number of spray on wheel protectants eg armour all/autoglym / simoniz along with normal body wax but dont seem to make much difference. Wondered what others are using on their alloys - anyone recommend any decent wheel waxes/ protectors - cheers
