I have cleaned a CD in an ultrasonic bath before.

It sounded much better after so I decided to do it again and put the heater on. Big mistake, the bloody top label came off and now it wont play. Well it will but it sounds like Norman Collier and nothing like Sheryl Crow.

I wont be doing it again.

Pssst, Nick, you missed out the extra 2% where I need help with the maths.

giggles!

Well, we all know that 1 + 1 = 3 for large values of 1

One could almost say 'pregnant' or 'generous 1s.

You brutes! I've been reading Merlin Blencowe's latest tome and trying to get my head around imaginary numbers and phase relationships an' now you's lot are telling me theres 'generous' and 'pregnant' 1's too.

Ah, but you're ignoring the multiplacative identity

Thanks Stu for details of your experience.

When you say it sounded much better after the first (cold) clean can you expand on that at all ?

Oh I spect so our DtB.

Always best to do that I find.

I did mean multiplicative identity..but you can ignore either I don't think I care much anymore....

I experienced more atmosphere of the recording. The cd was fairly grubby and so i was not surprised it got better. It skipped on one track and this was much improved after the first clean. There must have been more information coming through..

As things in an ultrasonic bath vibrate along with it, i think it is important to rest the cd on something that will protect it.

I've just ordered a 2.5 Ltr ultrasonic cleaner.

Not specifically for CD cleaning but I will give CDs a go.
