It is worth a try, Tom. WARNING, keep it far away from your cartridge!
The idea is to hold the magnet close to the lp without touching them. Move the eraser or the lp around to be sure the field gets everywhere. Then slowly remove the lp from the magnetic field so that "things" are left evenly dispersed.
Listen to an lp first. Then try the demag. If done correctly you should hear more low level detail and clarity.
Once you get the hang of it you can apply the same technique to your cables and tubes, if you have them. Just remove them from your system and do the demag'ing on the floor or a table.
