I'm sure many people have had the same issue, but need some advice regarding cleaning my speedlines. Basically, the steel outer rim is a pain in the **** to get clean, and often looks pitted and dirty. At the moment the only way of getting them clean, is to apply some serious pressure with a non abrasive brush, although this is not ideal as I'm worried about scratching the surface. Someone out there must know of a suitable split rim cleaner that brings them up well without costing me the skin on my knuckles and the danger of damaging the wheel through excessive scrubbing. Any help would be appreciated!
