it depends what CD, but its a roll of the dice to use isopropyl alcohol.

I used it to get the “Blockbuster (Do not remove)” sticker off a ps1 game that i bought at a retro game store. It covered the entire disc. I thought I was going to ruin it. but I decided I had no choice as it was getting caught in my PS2 and would potentially break both if I left it alone.

It worked out, but it was a scary and calculated risk.
