A super fast and super easy way to clean metal components, Finish Line Speed Clean is the bicycling equivalent of those spray-it-on wipe-it-off no-scrubbing-required household cleaners. Finish Line Speed Clean has the power to instantly dissolve and remove grease and grime from disc brake rotors, chains, cogs, chainrings and any other part that needs a through cleaning. Finish Line Speed Clean leaves no oily residue. Safe to use on disc brake rotors. Also excellent for flash-cleaning chainsets, cogs and chains. Melts away grease and grime. Fast evaporating - no water rinsing required. Speed Clean's extremely low surface tension will displace moisture from nooks and crannies, making it good to use after a wet ride to take care of your bike. Making the component as clean as possible ensures you get maximum benefit from the lubricant you then apply to it. (Oiling mucky components doesn't do your bike any favours.) 558ml spray can. The Aerosol is CFC free, and exceeds the Californian Clean Air Resource Board VOC standards.
