How often to demagnetize mc cartridges?


Just bought a used sumiko fluxbuster and demagnetized my Lyra Etna for the first time.  Pretty nice improvements in sound!  How often should cartridges be demagnetized?

I use the Cardas Sweep Record every few months and find that it is
worthwhile to do. But my limited understanding is that this is a very
different (and probably more lightweight) process than the demagnetization provided by the Sumiko Fluxbuster and that kind of direct demagnetization, particularly if overdone, can be harmful. 

AJ Van den Hul, for example, strongly recommends against 
demagnetization with stuff like the fluxbuster. 

There are some interesting comments below from JCarr of 
Lyra from a post at Audioasylum.
