Hi, i was just looking at bike stores and online bike stores and when i see a section for lubs i also see cleaners but not alot, i was wondering if alot of these big bottle lubricants act as a cleaning agent also. for example could i lub the chain then rinse it off then lub it? or what? the main thing im trying to get here is im just trying to keep my crank and chain and derailers clean, does anyone have any advice. THANK YOU.
