To preserve the value of your bicycle and to avoid unnecessary repairs, you should maintain it regularly. For cleaning your bike, it is recommended to use tenside or phosphate cleaners, because they do not harm the sensitive rubber parts of your bike. The chain is cleaned best with an old rag and then oiled anew sparingly. All joints and movable parts of a bike should be maintained with oil as well. In order to take care of the frame, you may use a preserving wax layer.
