If you have a CD Player, you need to do this periodically...

Well, I ordered one, thanks to Jerryg123's post.

With so many recommendations, it was hard to resist for a paltry $20.

I just checked the link again and saw that they are sold out now.

Not to worry, there's a couple of sellers on eBay selling used ones for $50. 🥴

Also don't forget to protect your player from direct sunlight.

I suspect it’s not magnetism but static electricity that builds up on discs. What magnetic material is on a disc?

Ink used on the labels may contain metal particles.

I believe static can build up on the clear polycarbonate plastic layer

The green CD pens actually work by the way.

Derisive comments serve only to burnish reputation among those who find it easier to dismiss out of hand than do the work of finding out for themselves. Credit and props to those who do put a little more effort into doing audio than expounding on that which they do not know.

Agree 100%

I  use the Isotek System Tune Up Disc , it includes a demagnetization track amongst the other tuneup tracks
