STYLAST Stylus Treatment is effective through the entire play of one side of an LP record. A bottle typically lasts 3-4 years for most users.
Two characteristics determine stylus lifetime: physical wear of the stylus contact faces, and the condition of the stylus suspension system. Stylast addresses both of these failure types.
Over time, wear of the contact faces becomes apparent as noise and distortion, and as seen with microscopic examination. To prevent wear to the stylus, Stylast behaves similar to a microscopic gas bearing. As the record plays, Stylast transforms into a gas at the point of contact, reducing friction and also dissipating heat.
Hardening of the elastomeric components through oxidation and loss of plasticizers causes stylus suspension failure. In the worst cases this results in collapse of the suspension. STYLAST Stylus Treatment addresses these failure types. Although Stylast is applied to the stylus tip, its extraordinarily low surface tension allows it to work its way upward over time along the stylus cantilever towards the suspension. Stylast absorbs into the elastomeric suspension and prevents it from hardening due to age, heat, atmospheric pollutants, dry air, or harsh cleaners.
