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?

Is the primary question not about ''coil core''? Iron core is used
in order to increase the output.'' Coreless'' kinds as the expression
suggest have no ''core''. It is this ''iron core'' which get ''magnetic
saturated'' and may need demagnetisation?
