Query: Cleaning Mode Does Damage!

I must agree with the other shopper who found this unit damaging his discs. In cleaning mode, the Optifix Pro leaves a hazy film on the disc, with radial swirl patterns, that I have not been able to remove. An effective cleaner should leave a disc shiny and bright, free of haze. According to Memorex, this haze is caused by the pads and solution and can be wiped off -- but I wasn't able to wipe it off. I would have to call this product UNACCEPTABLE, and I am returning it for a refund. I guess I'll have to pick up one of the Maxell cleaners; they're poorly made of cheap plastic, but at least they clean a disc effectively and feature reusable pads...
