Cleeds, I was simply responding to your comments which seem rather odd. At any rate your previous comments were a perversion of the subject at hand thus misleading.
Antinn, CFCs were banned in certain high use applications such as air conditioners. The worry was that they were breaking down the Oxone layer. They are readily available in various forms used for other purposes. This is the one I use https://www.grainger.com/product/5YK77?gclid=CjwKCAiAq8f-BRBtEiwAGr3DgW8iLDfylpAiijn-6L6umNg4_a4W971...
CRC also makes a CFC free formulation (green bottle) This one might damage PVC I do not know but rest assured the CFC version does no immediate harm to PVC even if you soak the record for a week because unlike several commentators here I have done it. As you note there are various CFCs with varying boiling points. The ones in use now have relatively high boiling points.
