Playstation Help?

[brentrent2779]

Hi all just wondering if anyone can help me out!!! My playstation 3 is leaving marks around every disc i put in the system...I think its dust but not really sure. I have called playstation service number and talked to some people about it..Now i have been told either try one of those cleaning dvd's put it in the system and see what happens.....OR try compressed gas air thing..The one i have is called Dust-off professional..the original compressed gas duster...so I want to know if anyone knows what i should try??? The dvd cleaners that i have seen at stores don't say anything about blu-ray or PS3 so i'm kind of worried about trying that...and of course Compressed gas thing scares me too...I just don't feel like taking my whole system into the Sony store and having them send it away lol.Thanks alot for your help!!
