cartridge demagnetization

Thanks for all the input; Czbbcl: I did watch that video on UTube. Does anyone not agree that method is safe and effective?

In that YouTube video, it really isn't a demag, it's a deflux. Not the same thing, but I'm sure it won't harm anything and could be worth a try.

If it was a real demag, the MM cartridges he claims also benefit from this treatment, would be ruined.

And what demag devices do folks recommend?
