Lens Cleaner in DVD-Rom Drive

[Headly]

Not really a question just something I just realized. I have been having problems backing up one scratch game. It wasn't terribly scratch, I've backed up worse, but at 64% I would get a Pxengine error. Happened about 8 times. Finally, since i had backed up worse before, I decided to try and run my DVD lense cleaner through my drive. Next try it made a perfect copy. Just thought this might be a good tip for those who put as many hours as I do on your drives. I have noticed that my lense cleaner disc is actually getting greasy looking behind the bristles from all the grime.
