I use a PTFE based "lubricant" applied with a fine-haired brush / sponge thing. It used to be marketed as "Soundguard" and most of my vinyl collection from the 60s-80s had been previously treated with it. On retiring and moving here, I resurrected the vinyl player and subsequently discovered "Permostat" marketed by Milty products. It seems to be the same stuff so I use it always. It works by leaving a thin layer of PTFE in the groove, which lubricates the stylus' passage, allowing it to push aside bits of muck and to maintain a better contact with the groove walls. The sonic improvement is quite noticeable and the listening experience much improved. It can't get rid of recorded backgrounds like tape hiss, vent noise or rumble, but it has the added benefit that antiskating compensation is much reduced, demonstrating that reduction in friction between stylus and groove. An internet search should find a supplier for you if you want to try it.
It is NOT a wet playing system.
