You may be able to clean any disc and remove the scratches without consequences once or twice,
but it does not help with disc rot. I've had a lot of PlayStation 3 BluRay games get disc rot. More so then my DVD and CD's. And As long as my DVDs and CD games and music is well stored, and put in the case they usually stay in fine shape
I store my PlayStation 3 blurays in the same location as my other games and I've lost a lot of them, I going to try to run one of them anyway because I hate replacing my Call Of Duty PS3 games I've already had to replace 2 Call Of Duty Black Ops 1 and my 2nd Call Of Duty Modern Warfare 2 has a spot on it. that series of PS3 discs tends to get data holes in them
Please if your reading this it's a good time to check all your PlayStation 3 games, because according to the internet I'm not the only one suffering pin holes sized chunks of cover art and light shine through the disc.
in my PlayStation 3 games. I heard that and even some PS4 games can be found like that as well
