The Last Factory makes a vinyl preservative that prevents wear in the groove of an LP (an LP has only one continuous groove, not multiple grooves). It is used by The Library Of Congress and many record collectors & audiophiles. But you need to start with a clean groove before applying the preservative. That means a wet cleaning, either by means of a vacuum machine (VPI, Okki Nokki, Nitty Gritty, Record Doctor, etc.) or cavitation/ultrasonic.
Over time, with playing constant playing, do vinyl records wear out?
I am resurrecting my 60's, 70's & 80's LPs. None have a clean apart from the cursory anti-static brush. My question is do these circular vinyl music discs wear out. With a new cartridge needle, gunge or no gunge in the groves, the hard needle material must wear away the indentations in a vinyl record. So no amount of cleaning will save them over time. Friction will win out...
