Cleaning a DVD is a relatively simple process. You will need a soft, lint-free cloth, and a gentle cleaner or rubbing alcohol.
To clean the DVD, first use the cloth to wipe off any surface dirt or dust. Then, using a gentle circular motion, apply the cleaner or alcohol to the cloth and wipe the DVD. Be sure to avoid getting the cleaner or alcohol on the edges of the DVD, as this could cause it to become unplayable.
It is important to clean a DVD regularly, as dust and dirt can cause it to become scratched and unplayable.
