Hi!

Have your friend hide the magnets from the kids. The internal
degauss should take care of the remaining spots provided it
works.

Sometimes it isn't stout enough to do the job. Some years back, my
younger brothers managed to put a faint "blob" on a MAG Innovision 17"
CRT. No amount of degaussing with the monitor's built in coil would do
the job. Even though the coil came on at every power up, it just
didn't seem to have the oomph. Operating it manually through the
monitor's menu did not help.

Being busy at the time, I took a quick look and decided that they'd
damaged the monitor's picture tube. And then, after a while, I managed
to acquire a large electric bulk eraser, which I eventually decided to
try using as a degaussing wand for this monitor.

It worked brilliantly. I started from several feet away by turning it
on and moved very slowly toward the CRT itself. Then I ran it slowly
around the CRT face, maintaining several inches worth of distance.
When I was satisfied, I moved away the same several feet and shut the
coil off.

I have successfully degaussed CRT monitors using an old magnetron magnet
suspended from a stout rubber band fastened to a bent wire in the a hole in
the center of the magnet.

I would wind up the magnet/rubber band combo and let it spin rapidly
Holding it near the monitor and slowly moving it away as it spun.

Any strong and rapidly spinning magnet that is aligned so that the magnetic
field alternates directions should work.

Some 'bulk erasers' spin a magnet using an electric motor.
