Do I need a dvd cleaner and what kind

Hello
DVD cleaner is a kind of CD, which will have cleaning pads sticked on it. When we insert the disc in any disc player, this cleaning pad will come in contact with the lens of the reading head. As the cleaning CD spins at hing speed inside the disc player, it will wipe out all the dirt and dust, if accumulated on the lens. Thus cleaning of laser pickup lens occurs.
This cleaning disc can be boutght from most of the electronic spare part shops at your town. Even after using this disc, your DVD player does not reads any disc, its laser pickup assembly is faulty, and should be replaced. OK.
