[Rant] I am too dumb to be left alive. I just tried to clean a CD with Isopropyl Alcohol...

It waited 31 years just for me to do this.
Does this damage the label or data side?
The damage was done from label side, however with CDs there's just a thin lacquer layer below the label and that's it.

Which is why you also shouldn't write onto CDs with permanent markers.
DVDs on the other hand have a relatively thick plastic layer on top, offering fairly good protection.

Can’t CDs also have two layers of plastic? I thought it was just cheap CDs that printed the label directly onto the data layer.
