Commonly, if your CDs and DVDs cannot be read by your computer, video or audio player the disc has been over-used or scratched. Finger prints or other smudges can also make your disc unreadable. Cleaning your Blu-ray disc once a week or month is necessary.
Cleaning your Blu-ray disc:
- Water and Micro-fiber towel. Cleaning your Blu-ray with water can remove fingerprints from your disc. First, rinse the bottom part of your Blu-ray with clean water. Then gently remove the water on your Blu-ray disc using the Micro-fiber towel. The Micro-fiber towel is important, because the fabric used in the towel is alpine micro-fiber yarn. The yarn is made from natural materials that remove fingerprints and lessen scratches from an optical disc. You can also purchase other optical disc cleaning products over the Internet. Just type a query on any search engine, and you'll get a variety of stores to choose from.
