Good Product or Nonsense?

A friend loaned me his CD cleaner. I have a photo to upload but there seems no accommodation for this.
'OPTRIX" is the name. Label says it is a clarifier, cleanser for CDs and also stops "Skipping". Cures cancer?
Comments from those who have used this please?

I used it on all my cds. There is an improvement. Careful with gold cds, there might be some haze left, does no damage as far as I can tell and they sound better too. Follow the directions precisely.
No idea if that product works, there are a lot of snake oil cleaning products.
But LAST offers a CD cleaner which is pretty popular. And they have a good track record with their vinyl preservative.

There has been a boatload of CD cleaners/clarifiers/improvers over the years, Optrix was one of the first, what 20 years ago, maybe 25. The best in terms of sound quality were auric Illuminator, the shark oil stuff from Nanotech, and Liquid Resolution. Positive Feedback has an article reviewing a bunch of them, Lotions Eleven.😄
