Phono cartridges use an elastomer (rubbery stuff) to mount the stylus in a compliant manner. All elastomers harden up with age. Sometimes (often) they can be softened up again by treatment with a fluid. This is how the car automatic transmission "tune up" products work. They soften the seals that have become hard and leaky with age.
So there is good technical reason to believe that Stylast would work. Auto transmission "tune up" stuff would probably work just as well, at a fraction of the cost. Put a drop in your cartridge and the rest in your car.
