Turntable Maintainance

How often do you clean or replace the drive belt.
Wouldn't alcohol dry out and eventually crack a belt and boiling it stretch it out and weaken it? I am surprised VPI recommended that; as a former TNT own we I don't remember that one! Talc I do remember and used it often.
Nope. They weren't rubber, so no worries with the alcohol. And the boiling process actually seemed to shrink the belts. In any event, they lasted close to forever. I replaced mine once in approx. 12 years and the new ones were no more stretched or damaged than the original ones.
