What is the best way to clean DVD's? I have tried plain water and that doesn't work very well. What about those cleaning kits that you can buy that has some pads and a cleaning solution? Do they work well? And what is the best procedure about cleaning dvd's? Do you go straight from the center to the outside or what? What kind of cloth do you use dry them off with? I am thinking about doing "spring cleaning" and wish to clean all my dvd's. Any help is appreaciated.
