In short, No, a CD/DVD player simply shines a laser at the disk.
They wont be damaged any more than a torch would be if you shined it at one.

Thank you for the replies and for informing us that residue does not damage the actual player.
I think what these questions come town to is how CDs and DVDs are protected from all types of products and whether that protective layer protects the contents from things like handwashing products.

I bought my first CDs in 1986, and I haven't noticed any failing yet. |
Neither have I, and I bought my first CDs in the early 90s. Yes the odd track on the odd disc doesn't play properly but it's very rare and from memory it's generally the last disc on the CD which has become corrupted over time.
