Not on my LP's, like they said ^^^
Optimal LP playback is achieved when the playback stylus traces the identical path as was traced by the cutting stylus. Gunking up the groove surfaces with *anything* necessarily interferes with that goal. One good look at LP grooves and a modern stylus at 200X magnification or better will convince you that *nothing* is too fine to interfere with that interface.
No Sound Guard. No Groove Glide (yuck). No Last. Just use the best available cleaning regimen, which Rushton already described, and a well made, well maintained RCM.
P.S. Don't even save the brush. It's already contaminated with old Sound Guard. Toss the lot.
