here in the UK, a DVD/CD Cleaner kit can be purchased for £1 in the cheapo shops. (99p Shop/£1 Store etc.)
It is important DVD/CD is stated on them as a CD kit alone may not be good enough for a DVD drive.
They come with a cleaning disc and a container of cleaning fluid (isopropyl alcohol). Again important the kit contains this fluid, as some have no fluid and rely on air pressure to clean when disk rotates. These are not as good.
Surely you know someone over here due to return home soon who could bring some kits, or who could post some kits to you.
Not sure about the note on the CD (should this be DVD?) spindle concerning unreadable DVD's.
Might be something to do with region code.
Does the User Manual advise on this?
Maybe if you advised Laptop Make and Model it might help.
Please advise back on progress.
Good Luck - Keep us posted.
