                        If cleaning of the frame is a matter of carefulness,
                        then cleaning of the chain is a matter of necessity.  
                        No kidding! 
                          
                        1. Introduction
                        Cleaning the
                        bike, but not only the bike, is for sure the least
                        amusing task. Some bikers do not clean their bikes at
                        all. They let dirt to pile up until the gravity gets it
                        off. Well, there are quite some reasons why this is not
                        good: 
                        
                          - 
                            
dirt,
                            which remains on the bike, slowly finds its way into
                            the bike components' interior - bearings, etc. 
                            because of which the wear is more rapid and the life
                            span is thus shorter

the
                            bike works worse: gear shifting is not that smooth,
                            breaks are difficult to apply, etc.

damage
                            is hidden, for example cracks in the frame can not
                            be noticed on time  
                          - 
                            
clean
                            bike is nice to ride  
                         
                          
                        In summer, when it's dry, dust from macadam roads and
                        cart tracks gathers in thin layers on frame and other parts of your mountain bike. After rain and in wet periods dust on
                        pathways changes into mud, which is even more annoying. In
                        any case no one can avoid regular and  frequent cleaning. This is especially true for the chain. 
                         
                        If you experience a close encounter with a bigger amount
                        of mud, then you have to do a complete general cleaning (chapters
                        1 - 7), which usually occurs a few times a season.
                        Otherwise you have to perform a basic drive train
                        cleaning every couple of dozen kilometers, which is
                        basically every trip
                        (chapters 6 and 7). If you don't, the drive train wear
                        will be much faster.
