Your Record Preservative evaporates differently now. What changed? -T.H.

The Record Preservative I bought some time ago (and still have some bottles) has a volatile carrier which when applied evaporates in a flash. The bottle I just bought apparently uses a water-based carrier and stays around longer. What happened??? T.H.

The original carrier was Freon TF 113 which contained small amounts of Chlorine as part of its chemistry.  Because free Chlorine has been implicated as an ozone depleting substance, we began a process of finding a similar carrier that was Chlorine free more than 10 years ago. The new carrier replaces Chlorine with Fluorine which does not have an ozone depleting potential. There is no water at all in LAST Record Preservative only the preservation components and the carrier. 
Hope this helps, Walter Davies
