Last stylus preservative...anyone still use it?

I used Stylast preservative back in the early 80's. I don't disagree that it can help preserve a stylus, but what happened to me was the stuff migrated up the boron tube cantilever and gummed up the fragile coils in my high output moving coil cartridge, causing one channel to go dead completely. This equaled one dead cartridge and a lot of expense. Not saying this will happen to everyone, but I had heard similar stories back then.

I use Onzow followed by Stylast before each side.  Never had any issues with cantilever creep.

Mr. M, was the Last migration confirmed as the cause of the coils going bad, or just assumed? A single swipe of the Last applicator brush doesn't contain much liquid, not enough to migrate all the way up the cantilever to the coils, I would think. Last creator Walter Davies did a lot of research before bringing the product to market. Knowing Walt as a hi-fi retailer before he started Last, that doesn't seem like a thing he would not have discovered.

A single swipe of the applicator brush has enough fluid on it to submerse the tip of the cantilever and stylus tip. I used a stylus magnifier to examine the tip to confirm this. The cartridge was broken apart to examine the inside. There were dried traces of Stylast on the coils.

mr_m, this is such an odd situation......not that we are not believing you, but so many of us have used Stylast for years/decades and had no such problem. Yet, there are similar reports such as yours all over the web??
Personally, I now use Onzow followed by the Stylast and am pretty sure that the Stylast ( which I have used for more than two decades) is a big factor in the continued life of my cartridge. OTOH, my single swipe of the applicator brush doesn’t immerse the tip of the cantilever and the stylus in enough fluid to coat the whole affair...far from it. I would therefore question if you applied far too much of the liquid??? Plus, you were applying the brush just once from back to front of the stylus and only at the tip??...as related in the Stylast instructions.
