How do you clean the lens on your PS3?

The lens cleaner may be helpful for poor performance and not cases of a total absence of performance where the disc can not be read. Some people use a Maxell Blu-ray Lens Cleaner. The $24.99 disc sells at Amazon.com for $14.13 and the Maxell Br-Game Blu-ray Game Lens Cleaner sells for $17.44
