That first guy either is a know-nothing asshat or he sells chains and sprockets. I usually go 300-600, depending on conditions (i.e., if its dirty, I clean it sooner). The stuff is dirt cheap and it doesn't take all that long. As a side, I don't clean every time I wax. If the chain is pretty black and gunked up - I clean. If its fairly clean & I'm about to take a 100 -200 mile scoot, I shot a coat on her.
