Stylus cleaner

Which have you found to be very effective...?
Funny, I just found on ZYX's site that they have a liquid cleaner UC-1 and a vibrating brush UP-1.
Last products for 40 years and excellent results.

Stylus cleaner, Stylast preservative, and Last stylus brush.

Sometimes the ZYX brush to remove dust collecting on the cantilever.
Hello everyone,I have some older last sylus cleaner my question is can it go bad over the years.THANK YOU
@g11657 -   I've been using the same bottle of Stylast, purchased circa 1990 (my second).    Still works, as well as day one.      Close tightly/use sparingly.
