Using this Finish Line bike cleaning kit is easy. First, take the degreaser and apply it to the chain and other components you want to clean. Then, use the compact - bristled end of the Grunge Brush to scrub the chain on all four sides. For parts like sprockets, derailleurs, crankset, brakes, and pedals, use the long - bristled end of the brush. After cleaning, dry the components well. Once dry, apply the lube to the chain for smooth operation. When using the degreaser, make sure to work in a well - ventilated area. Store the kit in a cool, dry place to keep the products in good condition. Also, don't forget to clean the brush after each use to maintain its effectiveness.
