A PlayStation 2 game disc can be adequately cleaned without a commercially available disc cleaner by using rubbing alcohol or window cleaner solution, a soft cloth, and cotton swabs. Dirty PlayStation game discs can affect the performance of the game and might cause skips and freezes while playing.
There are two main steps to clean a PlayStation 2 game disc using simple household items.
Examine the game disc for any fingerprint smudges. Fingerprints can be easily cleaned off by rotating the game disc counterclockwise while holding a soft cloth to the disc.
For more stubborn dirt, dab alcohol or window cleaning solution on a small part of the cloth and then clean the disc as discussed in step 1. Repeat the process if necessary.
