Red Faction Guerrilla Not Working! (PS3)

Hey! So i bought Red Faction Guerrilla today (2nd hand) for my ps3. I put it in, watched the first cutscene, it says loading Parker, and then i'm left in a desert abyss! I can't see my character only a glitched abyss. (this may be someone who can help on xbox 360 or pc, so ill take help from them aswell) How can i give the disc a good clean?

Thanks!
