Yes I read it all. My comment stands.

I've never cleaned a CD apart from wiping finger marks off.
I do have a few early ones with the 'rust' syndrome, where the cellulose lacquer has oxidised causing discolouration, but they play OK.
When in the cd juke box game we had to clean scratched cd's a lot. we found the best thing in the day was liquid brasso. But the cds had a better coating than they have now. Its easy to go too deep and totally screw the cd.
As said you go in one direction centre to outside. then wash and buff. If you look after your cd's you shouldnt need to do anything bar as Geoff says buff the odd fingermark or dust off.
I lived on a farm years ago, if we had any CD's that wouldn't cooperate we used to tie them to the shrubs around the garden to stop the deer from eating the plants, worked a treat.
You have a source for this? I would have thought they are still made on the same machines. It was a million quid to buy a CD 'pressing' machine back in the 1990s, can't see them being replaced with machines that do a worse job. Can't see why they would need to replace them.
The older stuff can be a bit of a crap shoot.
Recently I've been getting a good number of CDs from Music Magpie, and I've had a few problems with CDs classed as being "very good".
Closer inspection of the reflective side of the disc quite often reveals indentations from poor handling by the original owner.
When I get one like this I look to see if they have another, and order that, and so far the 2nd copy has always ripped perfectly.
The faulty copy is always sent back, and I've always been refunded.
Because of this I always give Music Magpie top feedback ratings.
Dirty discs get a wipe over with optical cleaning wipes, which I buy at Lidl.
Most of the wipes get used on my specs, and because they're non scratching they do superbly well on CDs.
the lacquer coatings have changed a fair bit, but in general they are pretty similar otherwise. some old ones the lacquer goes golden. think they were from a British plant. No-one is saying yet just how long they are going to last on average but they wont, as once thought last for centuries. Vinyl will outlast it
Probably PDO in Blackburn.
The plant was set up in 1980, on the old Mullard site, to manufacture laser video discs.
