Of course, for collectors you just have to keep the center label dry.
It hardly ever failed & didnt scratch the LP. We didnt clean them till they skipped from crud in the grooves.
That's is exactly what we did when I worked as a DJ in radio. Get them wet, then gently wipe with dish soap and a clean cloth. Then rinse and dry. Got rid of pops and crackles. Not good for a collectable record label, but we only cared about the sound on the air.
Back in my FM days we had a couple with seed burns. We had just received Styx II in the mail and was tracking it on air. The feature was short by one track.
