                        6. Cleaning the drive train
                        The most important part to clean is the chain. So, we
                        could call this chapter chain cleaning. You should have
                        a special rug only for this job, which is usually
                        really dirty.  
                          
                        Use the rug to wipe dry every chain link separately.
                        In this way the chain will shine bright and clean. You
                        can also deep clean the chain a few times a year with degreaser
                        or benzene. It is best to take the chain off the bike in
                        this case, or to use a special tool that you can get at
                        your local bike store. At the end it is very important
                        that after deep cleaning you also do a deep
                        lubricating!  
                          
                        You should always clean also the rear derailleur
                        jockeys. They are usually very much filled with dirt. A
                        smaller screwdriver is helpful at this job.  
                          
                        And there are also chain rings and rear sprockets
                        left to clean. If you want to do it perfectly you should
                        take them apart. But this is seldom done. The usual
                        way is just to rub the chain rings with the rug every
                        time the chain is being cleaned. You can get a special
                        brush for doing this. The brush is especially helpful at
                        cleaning the rear sprockets, which have tight deep
                        spaces between them.
