Agree with the above, and I've heard the sonic improvements and noted a lessening of stylus residues when playing new LPs cleaned vs. uncleaned.
Like it or not, pressing plants do not clean new LPs before sliding them into the jacket for sale. Trace contaminants are almost inevitable. If you play the LP without cleaning it, these will be dragged against the groovewalls, potentially damaging the new vinyl you just paid for, and/or build up on the stylus. There's no reason to take those risks when preventing them is so easy.
