Irresponsibly, I spilled milk on the PS3. It fell ON TOP of the PS3 so no damage or anything but really little milk went in the disk reader, I cleaned the parts that I could see and thought everything was fine. The next day, I ejected a CD and I had to eject it 3 times just for it to come out. I cleaned the reader using a stick with cotton and alcohol. The disk ejects properly now but it makes HUGE scratches on the disk, circular scratches. The scratches are like 5-6 layers of circular scratches. I don't know how to fix this. I don't want to damage my disks. Should I open my PS3? Please help, thanks.
