6. Scratches on CDs or DVDs
DVDs and CDs are no longer as popular as they used to be a few years ago. However, if you still have them and you know a few of them have scratches on their surface, you can try and restore the things. The method we are offering might sound odd. Luckily, it is effective. Rub the underside of the CD or DVD with the white part of the banana peel in circular motions. Do it for 1 minute, then wipe the substance with a clean and dry cloth. Finally, buff the disc with a glass cleaner.
