Using this chain cleaner kit is easy. First, make sure your bike has a rear derailleur as this cleaner is designed for such bikes. Attach the cleaner to your bike chain. Fill it up with Finish Line® Citrus or EcoTech™ Degreasers. The three rotating brushes, two side - plate scrubber pads, and the particle - grabbing magnet will do their job in less than a minute to clean the chain. When it comes to lubrication, use the included 60ml lube. This cleaner helps reduce mess and waste, and makes your lube last longer. As for maintenance, keep the cleaner in a dry place. After use, empty any remaining degreaser. If it accidentally drops, don't worry as it's made of strong plastic resin and can withstand such impacts.
