LAST - then and now?

Have been enjoying hauling records out of storage and listening to stuff I haven't heard in years. One thing I have noticed is that the records treated with LAST (probably a good 15 years or more ago) have held up really well.I know part of this is the cleaning on a Keith Monks machine they got before applying LAST - and possibly more importantly - I only went to the trouble with stuff I really liked.
At any rate - my question is this - has the base of the LAST product changed over the years? So many cleaning products were Freon based and are no longer made or made with different chemicals - does anyone know if LAST today is chemically identical to what it was 15 years ago?

With a properly aligned cartridge and clean records products like LAST are completely unnecessary. I have records from the 1950's forward that are dead quiet, many of which have thousands of playings.

7000 albums and 50 years is proof enough.

Maybe those meager (your words not mine) components need a supplementative product to sound right.

Good luck to you.

Chemicals similiar to "Freon" (Dupont's trade name for trichlorotriflouroethane) leave no residue.

In the case of LAST it's use was strictly as a carrier and had no efficacy of its' own. Much like solvent or water in paint, it served as a vehicle to carry the active ingredient(s).

In any case, there are other chemicals that have replaced halogentated (i.e. chlorine, flourine, and bromine based) products so there should be no difference in performance in LAST which is a useless product by any standard.

>>Last has been and still is a valuable help with keeping my collection alive. After 30 years in high end and with a $30K analog rig<<

That's nice.

When you get to 50 years and $150K in analog gear, we can talk.

Good luck to you.
