Everybody knows that CDs are not robust at all. I even do not want to lend it to someone. Whenever I lend CD, it never comes back to me safely. I don’t know why they do not manufacture it with casing like 3.5 diskettes. I think “Blu-ray Disc” will be in casing like that.
Anyway, if you have scratched CDs, here is the treatment. The treatment
is polishing the CD with toothpaste using cotton swab. After clearing
the scratches, wash the CD in water. Be careful when you polish. rub in
radial direction (going from the center outward).
