Last stylus preservative...anyone still use it?

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.

I have used the Lyra SPT for a few years now- excellent product imo!

daveyf. I'm not telling anyone not to buy this product. Just a problem I had. If you or the other posters use it regularly with no problems, by all means, keep using it. Did I put too much on my stylus or use it too often? Possibly. For me it was a costly situation. I just responded to the OP with a cautionary statement. I use Last's stylus cleaner religiously.A fine product to remove the crud off your stylus tip. It too, has a cautionary tale from cartridge makers warning against its use because it MAY soften the cement that holds the diamond to the cantilever causing the diamond to fall out. I never had this happen and have used it for years. Of course, I brush the stylus from back to front. no quicker way to destroy a fixed stylus cartridge than to brush it the wrong way....

I have used both the Last Stylus Preservative and Last Record Preservative since they came out.  I use Last Stylus Cleaner perhaps every three times I play a disk.  Have been doing this since the products were introduced (I am an OLD audiophile) with results as described above .... same cartridge with no stylus wear (Accuphase AC-2) and records that often sound like new.  The products are expensive but I recommend them.

I can only remark on my experience...

For years, I read the positive reviews of SPT..could not for the life of me believe that a stylus cleaner could actually make one’s lps sound better...

Fast forward to now...I got my first (bottle) in the other day. For years I’ve been mostly an ONZOW after each side and occasionally a Record Research stylus cleaner. Throw in an occasional use of the Magic Eraser. I’m still going the ONZOW way but having now used this SPT for several lp sides, I can say the sound is smoother, more relaxed and somewhat quieter. Even after my normal cleaning methods, I noticed some black stuff on the supplied brush that came with the SPT. A sign to me that my previous methods weren’t good enough.

I can steam of the brush. BTW, the supplied brush is miles away better than the other stylus fluid brushes. It allows an easier, more accurate way of getting to just the stylus.
