Using this Tru - Tension Cycle Drivetrain Cleaner is a breeze. First, pick the right nozzle for the job - the fan nozzle for larger areas and the pin nozzle for tight spots. Then, simply spray the cleaner onto the drivetrain. You'll see the dirt and grime start to drip away in seconds. After that, you can wipe off the loosened dirt. When it comes to maintenance, keep the cleaner in a cool, dry place. And don't forget, before using it on any paint or plastic part of your bike, test it in a small, hidden area to make sure there's no bad reaction.
