HI,
I started this as a reponse to a thread started by ejman. When I finished I realized it may be of more general interest.
I have been using Last Record Preservative and Stylast since around 1980. I do not use their cleaning products though they are probably excellent. I have developed my own which work well.
The products must be used correctly. The Preservative and Stylast are designed to work together as a system. You will not get the full benefit unless you use both. And, you need a good RCM with a strong motor and a horizontal platter, such as the VPI models, to apply Last. This will really fill out the tool set.
If used correctly, I believe the claims made by the Last Company. If not done right, you get less benefit, or maybe, none at all. Read their web site. I know it seems like snake oil but it's not. I have been promoting Last for years but folks don't seem to believe me. I really don’t blame folks because the claimed benefits are pretty amazing. The only way to know is to try it.
I have run a careful, disciplined, long term experiment to either confirm or deny their claim of extended stylus life. I started with a brand new line contact stylus (a Monster Alpha Genesis 1000 cartridge). Without Last, one could expect about 1000 hours of life before wear forced replacement. This was my second cartridge of this type. So, I knew what to expect. Also, long experience told me 1000 hours is about the typical life span of all styli no matter what their shape. It does not vary much. After all, a diamond is a diamond.
I checked for wear both by ear and, periodically, with my Shure stylus microscope. It reveals the truth. I set up an hour’s counter to keep track of playing time. The experiment was simple but required some determination and discipline. With an experiment like this, it is very important to be totally consistent. Here is how I did it.
I NEVER played a record unless it had been thoroughly cleaned on my VPI 17 RCM and then treated with the preservative. I NEVER played a side without first treating the stylus with Stylast. There were no exceptions. Even if a friend brought a favorite record over to my listening room for a listen, I would not play it unless I first washed and Lasted it. Once, a friend got pissed but calmed down when I explained the experiment. I Lasted his record then played it. It was good!
Cleaning (washing) the record is very important. The mold release residue that clings to all records must be removed in order to allow Last to form a chemical bond with the vinyl. Cleaning solutions should contain alcohol which is the only solvent I have found that will remove the mold release and not harm the vinyl.
I deep clean the stylus with an electronic stylus cleaner and isopropyl alcohol…about every 20 records. This removes a varnish-like residue that builds up on the stylus. I’m not sure of its origin. It may be Stylast baked onto the stylus surface by the heat build-up due to friction when playing a record. It is easily removed with a stylus cleaning brush and alcohol. Be careful!
The result? After 4000 hours the stylus still sounded new and the microscope revealed no wear at all. The experiment is still under way. From all indications, the stylus will last indefinitely. Probably, the stylus suspension will fail before the diamond wears out.
I think Last products are fantastic. They do what the manufacturer says they do. They have other benefits that I can confirm. Rather than repeat them here, check out Last's website at:

I realize that one experiment on one cartridge does not constitute a statistical truth. However, my long experience (over 45 years) with cartridges and my long term use of the Shure stylus microscope adds to the body of evidence that lends credibility to Last products and my experiment. I will continue the experiment because I am convinced that my records and styli are better off with Last than without. The experiment has become my normal record playing practice.
